Bowers & Wilkins CM Series - Tweeter on top

Tweeter on top

Every CM Series speaker now features Decoupled Double Dome tweeters. The top-of-the range CM10 S2 and CM6 S2 also get a tweeter-on-top, a feature taken from our most advanced reference speaker range, the 800 Series Diamond. Isolating the tweeter in this way aids imaging and dispersion, creating a more lifelike sound and an improved sense of space.

Nautilus tube


Not all sound is good. Sound from the rear of a tweeter can bounce around a cabinet and undermine the sound coming from the front. Nautilus Tapering Tubes, filled with absorbent wadding, reduce unwanted sound to a minimum.

Decoupled Double Dome tweeter


CM Series tweeters use a thin, light aluminium dome bonded to a thicker ring, to prevent distortion, for purer high notes. They are then 'decoupled' from the cabinets with a ring of synthetic gel, to cushion and remove vibration.

The properties that let Kevlar stop a bullet also make it ideal for stopping distorting resonances in a speaker cone. It delivers a cleaner, more precise sound, to a wider group of listeners. The combination of Kevlar and Fixed Suspension Transducer maximises the effect. This 'surroundless' suspension minimises distortion by converting unwanted energy into heat, not sound.

Anti-Resonance Plugs

The bass/mid drivers in CM Series feature Anti-Resonance Plugs, as seen in PM1. These mushroom-shaped devices fit inside the voice coils and reduce high-frequency break-up by ensuring better pistonic movement and damping resonances.

Decoupling

Tweeter on top isn’t the only thing the new CM10 S2 shares with 800 Series Diamond. It also features a midrange drive unit decoupled from the cabinet. Which helps isolate it from any resonance, delivering purer, cleaner sound.

Cabinet construction

All CM Series cabinets are made from real wood and are extensively braced. This not only leads to an aesthetically-pleasing, furniture-like finish, it also provides a solid platform for the high-quality drive units to work at their best. From this solid bass drive units are capable of delivering a more detailing, room filling performance.

Simple crossovers

The crossover sends the audio signal to the correct driver, depending on frequency. The simpler this component is, the better. The high-quality crossovers in CM Series use superior Mundorf capacitors for simply better audio.

Flowport

Great bass depends on smooth airflow. The dimples on the Flowport venting system aid flow much like the dimples on a golf ball. Noise is reduced to a minimum – and even with the volume right up, bass sounds smooth and tight.
