Q Acoustics Q B12 Subwoofer Active Home Cinema 12 Inch Sub Arctic White QA8702

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.

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.

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.

What Hi-Fi?, 5 Stars

"If you love the sound of Q Acoustics’ speaker packages but covet more power, the QB12 is as good a solution as we could hope for... this is the kind of performance that should slot easily into any comparably talented speaker set-up...As long as you have the space, budget and amiable enough neighbours, we say go for it. Just be prepared to host movie nights from now on."

"The new subwoofer sounds bigger and deeper than previous efforts from Q Acoustics, but it’s also more effortless in its delivery. The Q B12 integrates perfectly with the 3010i speakers, creating a balanced low frequency foundation. It’s also a very responsive design, revealing plenty of speed that ensures both music and movies sound equally as good."
