Belle finition et tenue des basses bonne.J'ai retiré 1 étoile car, je n'entends pas beaucoup la super basse, j'ai déjà une excellente installation avec des haut-parleurs de 115cm de haut et 2 woofers de 20 cm.J'ai acheté quand même un sub en pensant améliorer les basses d'un concert en blu-ray avec le son en DTS HD 7.1.Il n'y a pas beaucoup de différence seule les films catastrophe ou présentant beaucoup de percution sont quand même audible avec le sub.

I’ve had two Wharfedale SPC12 subwoofers in my home theatre setup for years and really liked their solid delivery. A lightning strike on the overhead power lines sadly killed them both and I looked to What HiFi for replacements. I bought these two subs on that recommendation, but was surprised at the difference in delivery, these are so much tighter and deliver more sub bass and less bass: I had to totally recalibrate my system. These most definitely are very refined, hifi subwoofers that whilst they can deliver massive punch, also deliver subtle sub bass to gently back up your main speakers. Very impressed, What HiFi were spot on.

This sub is matched with small floor standing Q40 mini tower (powered) speakers. The audio quality is excellent. I wish this big woofer came in Mahogany (for this location) but the gloss white is quite nice.

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..

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.

The sub works clean and powerful. There is no hesitation that if you are WATCHING a movie, adds a lot to the soundstage. On the contrary, at least I cannot figure it out, degrades a little the soundstage of a very good set of stereo speakers as the Opticon 6 that I have. It is my first day of listening. Time will tell if I will end using it just for LFE while I watch a movie. Even being this sub quite musical. Regards.

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.
