The QB 12 is the inaugural Q Acoustics subwoofer boasting a 12in driver. It is equipped with a 220-watt Class D amp for driving the extended-throw driver, furnishing tight, dynamic bass response, while the 50mm voice coil mitigates thermal compression. Matching perfectly with the Concept and 3000i series of Q Acoustics stereo and center speakers, Q B12 is prepared to accurately recreate both blockbuster movie special effects and the delicate details of bass instruments.
From the subtlest nuance to volcano all-action
220 watts of Class D power driving a long-throw 12in drive unit sounds like a recipe for action. And that’s exactly what it is - no Hollywood blockbuster soundtrack features explosions too loud, too deep or too powerful for Q B12 to handle. But power is nothing without control, and Q B12 is just as comfortable describing the nuances of a double bass or an electronic kick-drum.
Strength and control
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. Mechanical stability = aural satisfaction.
Ease, simplicity and performance
A reinforced MDF cabinet with a 36mm-thick baffle, a recessed and hidden terminal panel. Adjustable spiked feet with rubber caps. A choice of elegant, understated finishes. Q B12 is a simple and easy to position and set up as it is invigorating to listen to.
