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

Killer non ported sub… Fantastic articulate bass.. Needs little space to express itself but blends brilliantly with my other q acoustics speakers and even the 4 Atmos Mission modules… Lastly wonderful seller service.. Very impressive indeed…. Thanks.

I’ve been using the Q Acoustics QB12 SEALED Subwoofer from hifimart and it has completely changed the way I enjoy movies and music at home. What I appreciate most is how clean and steady it sounds even when I push the volume higher. The amplification feels smooth and effortless. I also like the simple rear panel control which makes it easy to adjust the settings to match the rest of my system. For its size and performance it offers outstanding value.
