Q Acoustics QB12 Active sub

The Q B12 is the first Q Acoustics subwoofer to feature a 12inch 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
No Hollywood blockbuster soundtrack features explosions too loud, too deep or too powerful for Q B12 to handle
Q B12’s sealed, ‘infinite baffle’ cabinet is cleverly braced to deliver maximum stiffness to its motor system and, as a consequence, minimum influence on those deep bass sounds
