The QB 12 is the first Q Acoustics subwoofer to feature a 12in driver. The big long-throw driver is 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, Q B12 is designed to be equally adept at reproducing big Hollywood action moments as it is the deep, subtle textures of bass instruments.
