CM10 First Impression
Bowers and Wilkins CM10 speakers breathes new life into the CM series. The new CM10s take the top spot formerly held by the venerable CM9 speakers.
Bowers and Wilkins releases the CM10 speakers in August. For now, we give you our first impressions of what these speakers have to offer.
Bowers and Wilkins CM10 pre-review
Right off the bat, you’ll notice the CM10’s tweeter placement bears striking resemblance to its bigger siblings, the 800 Diamond series speakers. The top-mounted tweeter technology utilized by 800 Diamond speakers gives you two distinct advantages over normal speaker cabinet construction:
- Top mounting prevents sound waves from re-radiating along sharp cabinet edges which interfere with the original timing of the sound waves you actually want to hear.
- Top mounting also allows fine adjustment of the time-alignment with the midrange driver for perfect phasing through the crossover region.
This is huge! Again, this is technology previously unavailable below the 800 series.
Another benefit to the top-mounted tweeter gives room for a third bass driver in the CM10 without making the cabinet significantly larger than the CM9. In fact, without the tweeter on top, the CM10’s cabinet is the same height as the CM9’s at 990mm. The third bass driver allows for extended bass response and less distortion at any volume level.
Of course, the CM10 speakers contain Bowers and Wilkins signature woven Kevlar® midrange driver. The same material that stops bullets also produces better sound compared to its counterparts. Since 1974, Bowers and Wilkins pioneered the use of Kevlar® in its speakers. Kevlar® benefits your speakers by producing more constant sound dispersion at all frequencies and less time-smearing.

In addition, the CM10 features Bowers and Wilkins’ FST mid range driver technology, allowing for greater cone response times and sound integrity. You’ll find FST mid ranges in 800 Diamond series, CM9, and 683 speakers. However, the CM10 is the first speaker outside of the 800 Diamond series to feature decoupled FST driver with gel mountings compressed via a tensioning rod to the back panel.

A Bowers and Wilkins Flowport reduces air flow turbulance in the CM10 for less compression at high volumes.

Bowers and Wilkins has outdone themselves with the CM10 speaker. It steps perfectly between the CM9 and the 800 Diamond Series. The blending of technology between the CM and 800 Diamond series in the CM10 further cements its solid position.
In Hi-Fi News’ Bowers and Wilkins CM10 review, Steve Harris writes:
“Thanks to its pod-mounted tweeter and FST mid driver, the CM10 offers a beautifully clean, detailed midrange and treble, with a big, open and impressive soundstage. I would have liked to discover a more organic quality in the bass, though, and it needs a capable amp to give of its best. But, while facing stiff competition at this price point, the CM10 is a worthy stepping-stone to B&W’s fl agship 800 Series.”
Bowers and Wilkins’ CM10 speaker simply sounds amazing. August can’t come soon enough!
