Q Acoustics QB12 Subwoofer

The Q B12 is the first in a new range of ultra powerful subwoofers. Designed to integrate and complement the award-winning Q Acoustics’ 3000i and Concept 5.1 speaker ranges, enabling ‘Plus’ packages of three existing home cinema packs. The Q B12 is finished in black or white, high gloss or vinyl to fit seamlessly into a new or existing home cinema set up.


The Q B12 Subwoofer has been specifically designed to deliver the ultimate cinematic highs and lows, all the floor-shaking bass you would expect from a plus-sized Subwoofer from Q Acoustics. Despite its magnificent size, it is precise, detailed and dynamic. With the integration of internal ‘Dart bracing’ providing additional cabinet rigidity and a reinforced MDF cabinet with a 36mm thick baffle, both work together to suppress cabinet resonance for a more controlled bass response and a more realistic cinematic experience.


The Q B12 has been designed to fit seamlessly within one of our multi-award winning home cinema packs including the Q Concept 5.1, Q 3050i 5.1 and the Q 3010i 5.1 available in a black and white, both vinyl and gloss, for the perfect match. Each has its merits with regards to the sound and setup and each can be sonically enhanced and upgraded creating a truly ‘Plus-Size’ cinema package with the addition of this 12inch subwoofer. The Q B12 is also perfect for those aiming to upgrade the low-end response in an existing home cinema set-up.


With its recessed and hidden rear terminal panel, hiding all plugs and cables neatly out through the base of the subwoofer, the Q B12 can be easily and discreetly positioned. Custom designed, adjustable spiked feet give firm support on carpeted floor and reinforced rubber caps supplied for use with wooden floors ensuring integral stability for your subwoofer.
