Most people know the B&W brand of loudspeakers by their once-unique
yellow color midrange cones and the odd-looking yet attractive
protruding tweeter assembly. B&W, which stands for John Bowers and Roy Wilkins, is a
British company that has been making great sounding loudspeakers since 1966.
Most recently, the company established their leadership in high performance
speakers in developing their famous $40,000 Nautilus loudspeaker. Ever
since that groundbreaking design, B&W has been introducing more practical and more affordable
loudspeaker systems based on the same technologies spearheaded in the
development of the Nautilus loudspeaker.
The first loudspeaker series to benefit is the high-end Nautilus 800
series ($1000 - $4000+ each). In 2000, the
company updated their popular CDM SE loudspeaker series with the re-designed
series as the second loudspeaker series to benefit from the technology developed
in the Nautilus loudspeaker. In fact the designation "NT" stands for
"Nautilus Technology". In my opinion, B&W has
successfully pushed their best Nautilus technology to this mid-range CDM NT
series, and as you shall see, this is particular true for the CDM 9NT.
As a testament to the appeal of B&W speakers in general, the company
claims that 80% of classical recordings are monitored using B&W speakers.
The latest example is the selection of the
B&W Nautilus 802 loudspeakers by world-renowned Skywalker Sound as
their in-studio mid-field monitors.
The CDM NT series consists of a number of different types
of speakers. Most are bass reflex in design and incorporate
various measures of B&W's unique technologies. The table below summarizes the entire CDM NT line with
some basic features and specifications.

For this review, I evaluated the flagship CDM 9NT and the center
channel CDM CNT. I chose the flagship CDM 9NT floorstanding
loudspeaker, since it features
the most technology from the reference-quality Nautilus 800 series (more on
this in the next section). I actually reviewed four CDM 9NT full-range
part of a high performance multi-channel audio system with a Super Audio CD
player as source equipment. The CDM CNT center channel
served as the obvious choice
as the fifth speaker for this setup, which I also use as my primary home theater. The total
loudspeaker system price? $5800. Though the price just
broaches the low range of audiophile territory, it's far from affordable for most "everyday consumers".
Yes, this is a loudspeaker system for serious enthusiasts (and those with a
The CDM 9NT: three-way vented
floorstanding flagship model
First, let's talk about the CDM 9NT and see what's unique
about this floorstanding loudspeaker. As the flagship speaker in the
CDM NT line, this 3-way loudspeaker sports the following features (for
pictures of these features, be sure to check out our photo
FST™ midrange driver: "FST"
stands for Fixed Suspension Transducer, a technology used in all of the
floorstanding loudspeakers from B&W in the award-winning Nautilus
800 series. The technology essentially allows the surroundless
(meaning there is no rubber surround) midrange cone to act as a "perfect piston" up to
2 kHz, which serves to maintain effective control over cone excursions.
Above this frequency, the radiating area effectively decreases to keep
both output and directivity virtually constant, while the outer region
of the cone encourages random vibrations that effectively cancel out any
undesirable sound colorations. The result is midrange performance with incredible detail, unsurpassed
clarity, and minimal sound coloration. Of the entire CDM NT series, only the flagship 9NT
loudspeaker includes this feature. The performance of this FST midrange
driver is one of the primary
reasons why I think the CDM 9NT is especially noteworthy.
Kevlar® midrange cone: This
yellow material used in bullet-proof vests provides a stiff material
ideal for midrange cones. The criss-cross weave of the Kevlar
fibers allows random vibrations to effectively cancel out undesirable
standing waves and resonances that typically plague cones made with
conventional materials. The benefit is midrange sound that is more neutral and less colored.
Nautilus™ technology tapered-tube tweeter:
This unique technology ensures far greater absorption of undesired radiation from the rear of
the diaphragm. The result is a more focused and natural high
frequency sound reproduction.
Tweeter pod & sloping top: This design
feature permits time-correct alignment of the treble frequencies in
relation to the midrange and bass frequencies by setting the dome tweeter back about
1/2 of an inch so
that it lines up longitudinally with the midrange and bass cones.
This allows the high frequency sounds reproduced by the alloy dome
tweeter to arrive at the listener's ears at the same time as those reproduced by the midrange
and woofer cones. Additionally, the tweeter pod works in
conjunction with the
sloping top to encourage better dispersion of high frequency sounds,
producing superb imaging
and a very life-like three-dimensional soundstage.
Beveled cabinet edges:
Designed to minimize diffraction of midrange frequencies that would be
caused by sharp 90-degree cabinet corners. The benefit is improved
imaging in the midrange frequencies. Observant audiophiles would
note that this benefit can only be fully realized if the protective dust
grilles are removed. So be sure to remove them during reference
listening sessions. Aesthetically speaking, the beveled cabinet
edges and the sloping top add visual appeal to what would have been another boring
boxy loudspeaker cabinet.
Large bass driver dustcap: The
woofer voice coil is
directly bonded to the back of a large "mushroom" dustcap to increase
rigidity and achieve greater control of bass cone excursions. The
advantage of this design is tighter bass response and lower distortion at higher volume
Flowport™ vent: This
unique vent port design uses dimpled surfaces to keep the airflow smooth over
its flaring port. This is the same aerodynamics technique used in golf balls to
minimize turbulence and maintain smooth airflow over the rear of the
ball (so that drag is minimized). B&W uses the Flowport design
in all of its vented loudspeakers to avoid the "chugging"
sound resulting from air compression and turbulence when the airflow
separates as it tries to navigate the flared opening. The acoustic benefit
of the Flowport design is tighter and more accurate bass response.
The two Kevlar/paper woofer cones are housed
together in their own
separate chamber and vent to a single Flowport vent that opens to the front
baffle. The 9NT's sensitivity is 90 dB, so it won't require a lot of
Its nominal impedance is 8 ohms and never drops below 3.0
ohms, so just about any decent quality receiver or amplifier can drive this
loudspeaker load. Of course, better receivers are more likely to bring
out the 9NT's full potential. For the serious audio enthusiast, there are two
pairs of high quality gold-plated binding posts. These permit the loudspeaker to
be bi-wired for improved resolution of low frequency detail and performance.
Alternatively, you can bi-amplify. If you don't want to bi-wire or
bi-amp, simply leave the gold-plated link in place and use one set of the
The CDM CNT: two-way vented
The CDM CNT is a
2-way center channel loudspeaker and shares a number of the CDM 9NT's features:
The CDM CNT doesn't have the FST midrange, but
features a Kevlar cone in a midrange-woofer configuration. The
midrange-bass driver vents to dual Flowport vents located on either side of the
driver. The CNT uses a single midrange-woofer driver for greater
midrange imaging accuracy. Many center channel speakers that use a side-by-side dual midrange-woofer
driver layout suffer from
uneven off-axis response due to sound wave mutual interference. This is also known as the "lobing
effect" and affects center channel clarity in some areas of the primary listening
The CNT's sensitivity is 91 dB. Like the 9NT, the CNT's nominal impedance is 8 ohms and never
drops below 4.6 ohms, so any decent quality
receiver or amplifier can drive this loudspeaker. For a
center channel speaker, I was pleasantly surprised to find two pairs
of high quality gold-plated binding posts, for bi-wiring or bi-amping.
Very few center channel loudspeakers offer this option.
This is one of many examples where B&W did not take shortcuts.
The CDM CNT struck
me as being large and quite heavy. It measures 11.8 inches high x 18.1 inches wide x 11.4
inches deep (300mm x 460 mm x 290 mm) and weighs a hefty 30 pounds (13.5 kg).
Its larger size and mass are justified when you realize that its frequency
response extends down to 50 Hz. Though its size and weight pay dividends in
acoustic performance, make sure the top of your TV or shelf is deep, wide,
and strong enough to accommodate the size and weight of this large
center speaker. If you have a large rear projection TV, make
sure to aim the speaker slightly downward towards the
listening area (ear level) for the best dialog and center channel
performance. The cabinet's height of nearly one foot can bring
the tweeter way above the plane of most listener's ears. The CDM CNT is magnetically shielded so that placement
near or on top of a TV would not interfere with the TV.
Finish, Cabinet Construction,
and Build Quality
The entire CDM NT series is available in three
real wood veneer finishes: black ash, red-stained
cherry, and natural cherrywood. Take a look at our photo
gallery for close-up pictures of each type of finish. I
the red-stained cherry and natural cherrywood finishes, and had some difficulty choosing between
the two. The natural cherrywood is nicely grained and its
natural wood color goes well with many wood furnishings you may
have in your listening/home theater room. The red-stained
cherry is rich and satiny looking. In the end, I chose the
natural cherrywood. This finish makes the loudspeakers look
more like fine furniture than some electronic gadget or black
box. Its natural wood finish looks great in my listening/home
theater room and adds warmth to a room that pulls double duty as the
family room. The wood veneer panels are thoughtfully and
aesthetically applied. The grain continues its run as the same sheet of veneer is
used on adjacent surfaces (front, top, back, and bottom
surfaces). The side panels are chosen such that the wood grain
pattern serves as a "fingerprint" for each loudspeaker
cabinet, each unique but with similar patterns.
Under the beautiful natural cherry real wood veneer finish,
(medium density fiberboard) forms the structure of the cabinet. MDF is frequently chosen by
loudspeaker manufacturers due to its inert acoustic properties. For
extra rigidity, three-quarter inch thick MDF boards are used and internally reinforced for extra
rigidity. In the CDM 9NT, the cabinet is separated into two chambers,
one for the midrange and the other for the two bass drivers. A solid cabinet construction is
critical to sonic performance, as it provides a solid enclosure that
minimizes vibrations and resonances that can significantly color the
sound. Rap on the outside of cabinet and all you'll hear is a
dull thud. Solid. As another indicator of cabinet build quality, the CDM 9NT
weighs 58 pounds (26.5 kg), while the CDM CNT weighs 30 pounds (13.5 kg).
The speaker grilles are sturdily
constructed of high-grade plastic and acoustically transparent fabric. They
pressure fit onto the
front baffle using grille holes and fully enclose all but the tweeter pod.
craftsmanship is first class all-around.
The large binding posts can accommodate any sort
of termination: spade lug, banana plug, pin connector, or bare
wire. They are gold-plated for maximum signal
integrity. The crossover networks are audiophile quality, using
separate circuit boards for treble, midrange, and bass, for maximum
clarity and minimal distortion.
Overall, the finish, cabinet construction, and build quality are top notch
across the board.
Set Up & Burn-In
B&W calls it "running-in", but otherwise
it's known as the burn-in period. This is when the mechanical parts
start to work with each other smoothly as a system to produce the designed
sound quality. I basically gave these speakers an extended
break-in period, playing stereo
music, movie surround sound tracks, and multi-channel music for two to three
hours a day for three weeks
before conducting any serious listening sessions for our review.
Though I did not make any notes during this period, I remembered that the
sonic performance became more open and smooth, especially in treble and
critical midrange frequencies.
After the burn-in period, I
fine tuned the loudspeakers' placement. As each manufacturer recommends proper placement guidelines for their speakers, I
followed B&W's guidance of placing the CDM 9NTs such that the
angle subtended by the left and right stereo pair is more or less 60
degrees in front of the primary listening position. For home
theater and multi-channel music, I placed the CDM CNT center
channel on top of my rear projection TV. The other pair
of 9NTs serve as surround speakers and were relegated near the rear
corners of the room, per the ITU loudspeaker
setup guideline for multi-channel music. During reference or review listening
sessions, I removed the grille covers for the most precise imaging
Listening Test: Stereo
I started my listening tests with a pair of CDM
9NTs playing stereo programs from audio
CDs. Immediately, I
was bowled over with the CDM 9NT's incredible imaging. The
soundstage was incredibly
three-dimensional. It extended far wider
than the physical placement of the speakers and far higher than the height of the speaker cabinet. A soundstage this
three-dimensional must be heard to believed. B&W's tag line
appropriately says, "listen and you'll see". I first heard the CDM
9NTs in a showroom that was wider than it was deep (approximately 30
feet wide by 20 feet deep). I put on Celine Dion's
"Hero" (from her album "The Colour of My Love",
Epic BK-57555) and closed my eyes. To my
astonishment, I heard a soundstage that extended far to the
periphery of my vision. Yes, I heard music coming from
about 150 degrees in front of me, while the pair of CDM 9NTs were
physically placed only 60 degrees apart! The absence of side
wall reflections in this wide listening room and B&W's superb
treble and midrange dispersion made this extraordinarily wide soundstage
possible. This experience was quite an epiphany for me. I've listen
to this recording many, many times before, but ignorant of its
superb imaging until now. It was this way with every quality
recording. As good as it was, the source was only audio CD.
really hear what these B&Ws can do, I turned to one of the new
high resolution audio formats, Super
Audio CD, to hopefully drive these loudspeakers to their fullest
potential. I started with Gloria
Estefan's "Alma Caribeńa" (stereo, Epic ES-62163).
Listening to the Cuban music at
reference volume was a mesmerizing experience. The 9NTs gave a thrilling
performance of "Dame Otra Oportunidad (Give Me Another Chance)".
The loudspeaker's tweeter, midrange, and woofer worked seamlessly
together to produce a sonic experience rich in musical texture and rhythm.
Gloria's strong and beautiful voice came across clearly even while the
mesmerizing beats of the percussion instruments pounded on. The stereo imaging
was exceptionally defined, depicting
each instrumental sound clearly its proper three-dimensional space.
Musical details of the acoustic guitars, horns, and percussion
instruments were accurately rendered. Treble was crystal clear
with no hint of harshness. Midrange was smooth, open, and
Bass was strong and tight, with a well behaved response that is more
typical of acoustic suspension cabinet designs than with vented
enclosures. I simply closed my eyes and bathed in the sonic
delight. By the end of the song, no words came to my
mind. Just emotions. A testament
to the incredible performances by the artists and the B&Ws.
Listening to Tchaikovsky's
Symphony No. 4 as performed by Lorin Maazel and the Cleveland
Telarc SACD-60563) (track #3), I felt as though the horn section was
listening room. The strings were holographic as they volleyed
between the left and right sides of the soundstage. The bass
was exhilarating, with clean definition and deeper extension into
the lower octaves than its specification response of 38 Hz would indicate. The entire wide range of orchestral instruments in
this marvelous recording was breathtakingly reproduced by the B&W,
in a performance that was spine-tingling. The 9NTs rendered the
full orchestral weight without overlooking any
subtle nuances of this fine recording. Everything, from the
lush sweeping violins to the immediacy of the percussion section,
was rendered with an incredible sense of realism and palpability
that only loudspeakers this sonically pure can offer.
I listened to quite a
few other stereo SACDs and audio CDs, and came to similar conclusions. The only shortcoming was a very slight
emphasis (richness) in certain treble frequencies. I emphasize
"very slight" since I wouldn't go as far as characterizing
the sound as "bright". It became immediately clear
to me that where the CDM 9NTs really shine is during playback of Super
Audio CDs. Reference quality recordings in this new high resolution
format played back on a high performance system and these CDM 9NTs
bring out a level of
transparency, openness, musicality, and imaging that undeniably will raise
every listener's reference level and expectations.
Listening Test: Multi-Channel Music
I turned to multi-channel SACDs. Listening to the multi-channel DSD track of Telarc's "The
Film Music of Jerry Goldsmith" SACD (SACD-60433) was a remarkable
experience. It was clearly the best audio experience this reviewer has
experienced. "Wow!" doesn't begin to describe the emotions I
felt. I am completely sold on multi-channel audio, particularly in the
SACD format. Stereo SACD is excellent,
but multi-channel SACD is even more so. The entire room is
transformed into one big
soundstage and the best way to describe the experience:
"virtual reality for sound". I was astonished and my
jaw dropped in disbelief. As you can imagine, the four 9NTs worked incredibly well
together as the front left and right mains and as the surround
speakers. The CNT center channel followed suit and pretty much
with the larger 9NTs to provide a virtually seamless front soundstage.
The presentation was certainly free from any sonic "holes" in the frequency spectrum.
The CNT performed exceptionally well thanks to superior
design features that it shares with the 9NT. And as I
suspected, the CNT's
larger form factor paid large dividends, allowing it to easily reach down
to 50 Hz and keep up with the 9NT's superb bass definition.
The realism was so incredible that all I had to do
was put in my favorite multi-channel SACD, close my
eyes, turn up the volume, and press play. Immediately, I was transported into the acoustic space of the recording studio or the venue of
the recording. The experience is completely and utterly
Listening Test: Movie Surround Sound
movie soundtracks, I configured the bass management of my receiver for
"large" speakers all around, including the
output to the CDM CNT center channel. I set the
subwoofer to "none" so that the low frequency effects
(LFE) in the ".1" channel would be re-directed to the
front main left and right speakers. Basically, I tested the CDM NT
loudspeaker system in 5.0-channel mode. So how good did demanding DVD-Video movie soundtracks sound? In short,
numerous demanding soundtracks such as "Star Wars: Episode 1,
The Phantom Menace", "Gladiator",
and "Toy Story 2",
the CDM NTs exhibited strong dynamics while simultaneously
demonstrating the capability to resolve low level details. The treble and midrange were
liquidity smooth, presenting a totally immersive and seamless
soundfield. The slight brightness
that I mentioned before was equalized out with my A/V receiver's
digital equalizer in home theater mode. The bass was strong, tight, and articulate.
Never mushy. Never floundered when pushed hard. Though the
CDM 9NTs' -3 dB point is 38 Hz, it seemed to have pushed much
lower. Having a pair of CDM 9NTs as surround speakers was
an enlightening experience. I've never realized how aggressive
and how much bass material sound designers put into the surround
Surely, some home theater purists may squawk at
the thought of using direct-radiating speakers (not to mention large
floorstanders) in surround channel applications. Admittedly,
direct firing speakers may not provide that diffuse surround effect
that is preferred by some for movie soundtracks. But this
configuration actually did quite well with my Sony ES A/V receiver's
"virtual 6.1-channel" mode for THX
Surround EX and DTS-ES
soundtracks, taking advantage of the precise imaging afforded by direct radiating speakers
to re-create that virtual surround back speaker. For me, the
full-range performance of the 9NTs more than compensated for the
"less than diffuse" surround effect. As
an example, every time the Yamaha grand piano DTS trailer plays, I
can feel the back of my sofa vibrating. Few bipole/dipole
surround speakers can reproduce that kind of visceral impact.
Given the importance of the center channel for
movie soundtracks, the CNT gave a strong performance.
Dialog was articulate and clear, with absolutely no signs of sibilance.
The Kevlar midrange-bass driver rendered every nuance of human speech
and song with utter precision. And the relatively deep bass response
projected most of the visceral impact of on-screen explosions. The
CNT center channel's single midrange-bass driver design fostered an even
sound dispersion across the primary seating areas, unlike some
horizontal dual midrange driver designs that are fraught with lobing
effects that can penalize off-axis performance.
Auditioning Tips - What to listen
for when you shop
Loudspeaker purchases are one of the more daunting
tasks of putting together a home audio or home theater system.
Here are some tips for best results
when auditioning the B&W CDM NT speakers in the showroom, to
make sure you're listening to them at the fullest potential:
Correct speaker placement: When
listening in a showroom, make sure the speakers are properly
placed for optimal stereo imaging. Place them at least 3 feet (1.5
meters) from the back wall and side walls, and about eight feet apart from
each other. Place your chair such that you and the two
speakers form an equilateral triangle. The speakers should
be spaced 60 degrees apart and symmetrically in front of
you. Then "toe in" the speakers about 20 to 35
degrees so that the speaker cones are somewhat pointed towards
you. Play with the toe-in angle to get the best stereo imaging.
Listen to stereo sources: The best and
most practical way to audition speakers is in 2-channel stereo
mode. Listen to the entire song and resist from
doing too many "A-B tests" (switching between speakers
frequently in the middle of the song).
With these tips, some time and patience,
you'll be able to hear these wonderful loudspeakers at their
best. Even if you're not seriously contemplating these
speakers, try them out anyways as a point of reference.
Competitive Models & Value - How does this model
After auditioning a number of loudspeakers in this
general price range from various manufacturers, I found that
comparisons are more appropriate to other loudspeakers from
B&W. And more specifically, I was compelled at how well the CDM 9NTs
performed in comparison to more expensive speakers from B&W.
The CDM 9NT is definitely a better value than the Nautilus 803s, 804s, and 805s.
They easily beat the acoustic performance of the Nautilus 805 bookshelf speakers
($1000 each) any
day. And in some ways, the CDM 9NTs outperform the more
expensive Nautilus 804s (the most affordable floorstanding speaker in the Nautilus 800
series at $1750 each). And dare I say the CDM 9NTs approached the performance of the
($2500 each). Certainly from this regard, the CDM 9NT is a very good value.
Compared to the less expensive CDM 7NT floorstanding
speakers ($1000 each), the CDM 9NT blows it away, with its 3-way
design. The two dedicated woofer drivers and the FST midrange driver
elevate the 9NT's performance closer to that of the Nautilus
800 series. Compared to the CDM 7NT, the CDM 9NT is a far better
loudspeaker and for the $300 price difference the 9NT is also a far better
Availability & Price - Where
can I buy this model & for how much?
The B&W lines of loudspeakers are sold worldwide in
over 65 countries. Look for these B&W CDM 9NT and CNT loudspeakers at your nearest
B&W authorized specialty electronics
retailer. As far as I know, there are no B&W authorized internet
I absolutely love the CDM 9NTs, as a stereo
pair and as a
quadruplet in a multi-channel audio / home theater system. The CDM CNT center channel
speaker nicely completes the set and is a
better-than-usual match. The CNT's
size and weight contribute to its great performance, but its unusually large
dimensions can make placement atop large rear projection TVs a little
difficult. But if you have room for it, the CDM CNT is a worthy
loudspeaker that provides a good measure of center channel
performance for home theater enthusiasts who are also serious multi-channel music connoisseurs.
All the technologies I discussed above boil down to a sonic performance
that leaves me in a state of bliss as a serious music listener, and in a state of
awe as a home
theater enthusiast. I'm talking about goose bumps all the way! The imaging is incredibly precise and detailed.
The resulting soundstage is incredibly three-dimensional, far exceeding the physical placement
of the speakers in both the horizontal and vertical axes.
This is a classical music listener's loudspeaker. Not that it can't handle
rock, jazz, country, rap, or other genres of music and home theater soundtracks.
In fact, there are
many and more affordable speakers that can reproduce those programs
well. But few can reproduce classical music and the new high-resolution audio
formats like SACD and DVD-Audio to the high level that the CDM 9NTs can.
that list gets a lot shorter when you limit the price to about $1300 each.
From this perspective, the CDM 9NT proves to be quite a value.
I suppose if you had the means, you could buy a pair of high performance loudspeakers that go
for $6000 or more. But why, when you can attain the high level of sonic performance
that these CDM 9NTs provide for a more reasonable $2600/pair. Better
yet, buy five of these B&W CDM 9NTs (or four with a CDM CNT center channel) and
experience what high-resolution multi-channel audio is all about. In fact,
the CDM 9NT's closest competitor aren't from competing loudspeaker
manufacturers, but rather B&W's own (and more expensive) Nautilus 800
series, specifically the Nautilus 804 ($3500/pair) and the Nautilus 803
($5000/pair). Oops! Maybe this is a secret that B&W doesn't want its
customers to know.
Overall the CDM 9NTs and CDM CNT make an awesome
combination for any serious home theater or audio enthusiast. I like these
speakers so much, I purchased these loudspeakers for my
reference system. That's just about the highest and most sincere
reviewer can give. I've had this CDM 9NT/CNT loudspeaker system for
about five months now, and I absolutely love them!
