Q Acoustics Q B12 subwoofer: a powerful new option for immersive home cinema sound

Q Acoustics today introduces the Q B12, the first in a new range of powerful subwoofers. Designed to work with the award-winning Q Acoustics’ 3000i and Concept 5.1 speaker range – and arriving in a matching finish – the Q B12 will be available alongside speakers in three home cinema packages for those seeking a bigger blockbuster sound to their home entertainment experience. The Q B12 is also available to purchase individually for movie fans wanting to boost the low-end audio on their existing set-up.

At the heart of the Q B12 sits a long-throw 12-inch driver with high sensitivity and superb dynamics, powered by an ultra-low distortion 220W Texas Instruments TPA3255 Class D amplifier. It’s the largest and most powerful subwoofer from Q Acoustics so far, with an active limiter and the amplifier’s proprietary PurePath Ultra-HD technology ensuring unwanted distortion is minimised across the board, resulting in a taut but forceful sound.

To help maintain performance levels a subtly engineered, custom die-cast aluminium heat sink on rear panel supports and cools the ultra-low distortion power amplifier and power supply. Elsewhere a 0º/180º phase switch, allows the user to optimise integration with left and right speakers for a seamless and balanced fidelity.

Given the powerful nature of the large driver unit, effective cabinet and driver bracing is crucial for a smooth low-end sonic performance. Q Acoustics has fitted a ‘dart brace’ internal design inside the subwoofer’s reinforced MDF cabinet. Not only does this provide superior mechanical stability to the driver but the reinforced rigidity reduces resonance and vibrations for an improved accurate bass response.

Adjustable spiked feet provide additional support when the Q B12 is placed on carpeted floors, with optional rubber caps for wooden and other hard surfaces also provided. The rear terminal panel has been cleverly designed to keep interior spaces free of unsightly wires. Recessed and hidden, it allows all plugs to be concealed and channel cables passed cleanly out through the subwoofer’s base.

The Q B12 is available now and included in the following 5.1 speaker packages:

  • Q Acoustics 3010i 5.1 PLUS (£1,250 / $1,695 / €1,545)
  • Q Acoustics 3050i 5.1 PLUS (£1,750 / $2,365 / €2,195)

  • Q Acoustics Concept 30 5.1 (£3,125 / $4,595 / €4,095)

It can also be purchased on its own in a matching finish (Black and White vinyl) to the Q Acoustics 3000i range for £579 / €699 / $749, or in a matching finish (Black and White gloss) to the Q Acoustics Concept range for £679 / €849 / $999
