The subtlest nuance to volcano all-action

The Q B12 Subwoofer from Q Acoustics is their first subwoofer to feature a 12 inch driver powered by an ultra low-distortion 220-watt Class D amplifier for tight, powerful bass response and features a 50mm voice coil for minimal thermal compression. Equally at home with Q Acoustics’ Concept and 3000i range of stereo and centre speakers, the Q B12 is equally adept at reproducing big Hollywood action moments as it is the deep, subtle textures of bass instruments.

A stunningly beautiful subwoofer

Designed with ease, simplicity and performance in mind, the stunningly beautiful B12A Subwoofer has a reinforced MDF cabinet with a 36mm-thick baffle, a recessed and hidden terminal panel and adjustable spiked feet with rubber caps. It is as simple and easy to position and set up as it is invigorating to listen to.
