Full Description
"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."
The Q B12 is an ultra-powerful subwoofer from Q Acoustics. Its purpose is to fit in with and complement Q Acoustics’ award-winning 3000i and Concept 5.1 speaker ranges. It adds deep bass performance to these ranges in a home cinema configuration or any other system you have.
This is the largest and most powerful subwoofer that Q Acoustics offers, making it an excellent choice to upgrade your existing home cinema system. It features proprietary PurePath Ultra-HD technology which thoroughly minimises unwanted distortion, resulting in a tight but strong and convincing sound.
Contributing to the delivery of this sound is a 12-inch long-throw driver, with great sensitivity and dynamic range across the low-end frequencies. This is powered by an ultra-low distortion 220W Texas Instruments TPA3255 Class D amplifier.
The Q B12 is available in two colour options: black or white, with both available in either a high gloss or matte vinyl finish to perfectly complement your existing system and home aesthetic.
Powerful Plus-Size Sub
The Q B12 Subwoofer has been designed for those ultimate cinematic lows, like the explosions and crashes in an action film. The Class D amplifier, capable of 220 Watts continuous power and 440 peak power, provides every bit of floor-shaking bass expected of a moderately-sized subwoofer like this. It is loud and proud so make sure your neighbours are ready for this addition to your cinema system! While capable of magnificent power and deep sound, it will comfortably stay calm and controlled in delicate moments, ensuring your speakers stay in the spotlight.
Big, Braced, and Baffled
Despite being one of the largest subwoofers produced by Q Acoustics, with its 12-inch driver and hefty power capabilities, the Q B12 is still precise, detailed and dynamic. Yet, when the time comes for serious sonic intensity, it's ready to rock! Thanks to the integration of 'Dart Bracing' and a 36mm thick baffle, the MDF cabinet is sufficiently reinforced to suppress distortion. The ‘Infinite Baffle’ enclosure also ensures maximum stiffness to the motor system, meaning you can enjoy all the power without distracting resonance or rattling.
Connection and Control
Beyond its power, sound quality, and design, the Q B12 Subwoofer is lauded for its ease of use and flexibility. The subwoofer's rear terminal panel has been recessed and hidden to add to the clean aesthetic while offering straightforward connectivity. In the recess, you’ll find a 0/180-degree phase switch as well as RCA connections. The subwoofer also features dials for crossover and level adjustments. For best results with this subwoofer, make sure you have sufficient space to let the sound flourish and consider adding an AV receiver (if you haven’t already) for better overall control.
