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 Acousticsโ Concept and 3000i range of stereo and centre speakers, QB12 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 volcano all-action
220 watts of Class D power driving a long throw 12-inch drive unit sounds like a recipe for action. And thatโs exactly what it is – no Hollywood blockbuster soundtrack features explosions too loud, too deep or too powerful for QB12 to handle. But power is nothing without control, and QB12 is just as comfortable describing the nuances of a double bass or an electronic kick-drum.
Strength and control
The QB12 subwooferโs sealed, โinfinite baffleโ cabinet is cleverly braced to deliver maximum stiffness to its motor system and, consequently, minimum influence on those deep bass sounds. Mechanical stability equals 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. The QB12 subwoofer is a simple and easy to position and set up as it is invigorating to listen to.
