Bowers & Wilkins B&W ASW 10 CM

Details for this product are shown below.

This versatile subwoofer compliments the rest of the CM range with the powerful, deep bass that has come to be expected from B&W's range of subwoofers.

Wrapped in an exquisitely veneered cabinet, the 10 inch dual voice coil paper/Kevlar® driver is driven and controlled by the mega efficient 500W audiophile standard Class D amplifier and switch mode power supply, delivering immense power when the signal demands.

This combination can move vast amounts of air yet not lose any of the control that is necessary for accurate low-frequency output.

At a live gig, a truly powerful, clean PA system will deliver bass with a drive and ‘punch’ that gets the blood pumping and sets the senses on fire. It’s hard to get that same excitement from a home hi-fi, but ensuring the mechanical integrity of the bass driver is essential to the pursuit. B&W’s bass drivers use a ‘mushroom’ type diaphragm construction, maximising rigidity by bonding the cone, dust cap and extended voice coil bobbin into a stiffening girder-like unit.
