Focal introduces CMS Sub at 127th AES

At 127th AES, Focal launched its CMS SUB, an active subwoofer designed to complement the frequency response of the CMS studio monitors for a smooth integration with the CMS50 and 65 monitors.
The 11” Polyglass cone woofer used in the CMS SUB is both very light and extremely rigid for a neutral and distortion-free response. This weight-to-rigidity ratio is obtained by applying a thin layer of hollow glass spheres on top of a cellulose-based cone. The high excursion capabilities of the CMS SUB woofer offer tight and controlled bass. The CMS SUB woofer was designed to be highly efficient to make sure that you can hear the slightest changes to compression settings.
BASH technology was selected by Focal's team of engineers for the output stage of the CMS SUB amplifier (300 W rms). After extensive listening sessions, this hybrid design was chosen for its sound quality combined with high efficiency. The rest of the amplifier is custom built and fine-tuned especially for the CMS SUB.
The CMS SUB features stereo inputs and outputs to facilitate the connection of a pair of CMS monitors. A dedicated LFE input allows the use of the CMS SUB in a multi-channel system. The subwoofer’s LO PASS settings have been optimised for quick and easy setup with CMS50 and 65 models. Phase inversion, phase adjustment and a mute switch can be remotely controlled by a standard foot pedal.
The high SPL of the CMS SUB (113 dB) can generate enormous internal pressure within the cabinet. To maximize rigidity and to eliminate cabinet resonance, the MDF used in its construction is almost one inch thick (22mm). The CMS SUB is equipped with a large front laminar port to facilitate its positioning in smaller studios or near a back wall.
