The ASW CM is technically similar to the ASW675, but is designed in classic CM 
Series style, with its aluminium front and choice of real wood veneers.
This versatile subwoofer is compact enough not to physically dominate the smaller 
room, but powerful enough to fill the larger room with powerful, deep bass from 
either music or movie based sources.
 
The rugged 250mm (10 in) driver, with its composite paper-Kevlar®-aluminium cone, 
large magnet and high-power voice coil, can move large volumes of air with exquisite 
control for accurate low-frequency output.
 
To ensure the driver can perform in the relatively compact cabinet, the subwoofer 
features a powerful 500W amplifier to apply the necessary equalisation. Equipped 
with audiophile full-range Class-D circuitry and a switch mode power supply, the 
amplifier is extremely efficient and operates reliably cool.
