The QB 12 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-action220 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 controlQ 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 performanceA 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.

Purchased this subwoofer in December and honestly I love it so much. First of all the sales team were amazing like they always are here!At first of course the subwoofer needs some time to wear in but when it does it transforms music and movies to the next level. I use it for all types of music whether it be R&B, New Jack Swing, Rap, Hip Hop, Bhangra, Reggae, Rock, Soul, Jungle, House, Latin, Grime, Garage and Drill and it performs on every genre. If you want to feel it in your chest no problem just turn it up and it can do it no problem. When it comes to movies this thing always performs and my mum tells me to turn it down when we watch a movie because i have it loud and she begins to feel sick due to the bass shaking her body.Trust me this thing is loud and is ... MorePurchased this subwoofer in December and honestly I love it so much.

I bought this week ago and I am very happy, Sound is amazing from the speakers
Wow! Make sure you have everything nailed down. It packs a punch! Looks so smart as well.
Awesome quality, sound quality is exceptional and doesn't distort at any volume I've played it at. Shakes the loose items of the house the way it should do, and I love it!
I bought this a couple of weeks ago and I'm delighted with the purchase. The build and sound quality from this subwoofer is amazing. It was the finishing touch to my home cinema set up. The bass quality is first class.
