Low in fireworks, good in supporting your overall sound
4 Stars
Low in fireworks, good in supporting your overall sound
Out of the box this wasn't nearly as present as an old 8" Definitive this replaced, BUT it immediately made the rest of my system sound so much better, and has improved over the last several weeks. That's the big selling point of the Q B12. My center sounds amazing now and the overall sound is fuller and more fleshed out. You'll likely have to run it hotter than a more powerful sub but there's still plenty of headroom. With the volume at half on the sub, I have my Yamaha receiver sending it a level of +3 (with the rest of the speakers around 0). It's a big, sturdy speaker, and I've found that I achieve a satisfying, bass-heavy sound without the rest of the house having to hear (or feel) it. So if chest-shattering, house-shaking bass is your top priority there are probably better options. The Q B12 will handle that assignment, but somewhat reluctantly. It would rather be the quiet kid in the corner acing every exam, only raising its voice when absolutely necessary.

5.0 out of 5 stars Outstanding subwoofer
Reviewed in the United Kingdom on September 3, 2023
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, the Q B 12 was 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 Denon X6400 in a 5.2.4 setup) beyond 50% of its maximum volume. Impressively, the Q B 12 blends seamlessly with my existing Q Acoustic speakers, 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

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.
