Description

Q Acoustics QB12 Subwoofer

The Q Acoustics QB12 Subwoofer is the first Q Acoustics subwoofer to feature a 12-inch 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.

From the subtlest nuance to all-action volcano

220 watts of Class D power driving a long-throw 12-inch 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.
