## Description

The Q B12 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. A choice of elegant, understated finishes. Crossover frequency range: 70 Hz - 225 Hz Frequency range: 28 Hz - 300 Hz

Review: The Q Acoustics Q B 12 subwoofer is a stellar addition to any audio setup. With "subtlety" and "integration" at its core, this product truly stands out. Having already invested in the Q Acoustics 3050i Home Cinema Plus, which came with the Q 3060S subwoofer, I sought to enhance the bass depth. Naturally, two Q B 12's were my top choice. Though my lounge is compact, and I'm conscious of not overwhelming my neighbors, I rarely need to push my sound system (powered by a Cinema 50 in a 5.4.4 setup) beyond 50% of its maximum volume. Impressively, the two Q B 12 blend seamlessly with my existing Q Acoustic speakers, (including 2 Q 3060S for the rear subwoofers) handling bass output and the LFE channel without producing any distracting “double bass” effects. The bass augmentation is truly exceptional, melding with other speakers to avoid any unnecessary “booming” or distortions. Some enthusiasts have observed heightened performance from their surround speakers with the QB12 taking charge. While I lean towards agreeing, a bit more experimentation on my part is warranted. The Q B 12's output is nuanced and balanced, adjusting effortlessly based on the demands of the soundtrack. For music enthusiasts, I set my subwoofers to LFE + main during a two-channel stereo output. The SB 12, once again, showcases its adeptness by adding depth to any music genre. It manages its output beautifully, ensuring the genuine richness of the track shines through. Bear in mind, the Q B 12 is sizable, necessitating ample space. I've opted for the carbon black finish across all my speakers, which exudes a sophisticated aesthetic. If you're willing to invest both financially and in the fine-tuning process, and have the space to accommodate, the Q B 12 is undoubtedly a wise acquisition
Review: Got this as a replacement for my old home theatre sub. Deep and punchy bass, doesnt really go sub sonic but works very well for both movies and music. Overall build quality and finish is very good.

### ⭐⭐⭐⭐⭐ Review
*by C***J on 6 October 2024*

I damaged my Mission subwoofer of 15 years. When in use watching a film everything shook. Just as well we have no connected neighbours. But music was a bass mess. But we only used it for action films. I came upon Q B12 by chance. Its won a few awards and Amazon had it an attractive price with 30 days free return. I took 5 mins to install where the Mission once stood. Same cables everything. Its very good with music, its suggested that you adjust the volume till you just about hear it when the front speakers are in use. Then down a touch. Films are a different experience. But one thing is for sure. Its not going back. .
