Amazon.com: Customer reviews: Q Acoustics Q B12 Subwoofer Carbon Black - Featuring Infinite Baffle Enclosure, 12" Driver, 220 Watt Class D Amplifier, 1.97" Voice Coil - Active Subwoofer for Home Theater Sound System

Reviewed in the United States on February 27, 2021

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.

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.

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

Powerful and tight bass

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.

These people at Q definitely don't disappoint! I originally bought the cheapest speakers, which are really good. I had a small - about half the size of this - sub, which at about the same price was admirably capable, but always worked very hard. This one doesn't work very hard, and produces great bass, and has enough control to blend in - with a gurt kick! The newer surround speakers (3020i) are also comparatively awesome. For a modern open plan home, with a well set-up array of speakers, this speaker definitely gets you where it's needed.

Crisp clear base

I bought this to complement my Q acoustics M20 speakers and it is amazing. No need to make a smiley face on an equaliser as you can just adjust the sub to the amount of base you like. Although, if you want your house to shake you can crank it up and ithe sub handles it no problem. Drum and base hasn't sounded this good for a long time. Super crisp base, nice looking box, would recommend.

Awsome... once broken in correctly

Reviewed in the United Kingdom on May 2, 2020

Color: Carbon BlackVerified Purchase

I was apprehensive about this subwoofer, although I have q acoustics 3020i fronts and love them but this is the first large size sub by Q acoustics and only 220w and my previous BK sub was 300w. Firstly the build quality is fantastic and matches the finish of my speakers, no nonsense controls and tidy hide away cables. Only thing I dislike is unlike the q acoustics speakers the front grille isnt removable mainly want that for cleaning purposes. When I first installed and powered on the sub I wanted to break in but on 30% gain with 80hz crossover couldnt even hear it, that much so the pioneer amp calibration software couldnt pick it up! I though great buy....not. However I think amplifiers in subs need a few hours to charge capacitors and for the sub to start flexing it muscles. After left on music for 2hrs I then slowly increased to 60% gain and it sprung to life and could be configured by amp software. A few days in and this sub is now awsome and can really push out some bass and worth at this price point of the what hifi 5 star review. For the price this is an excellent forward firing sub IF you give it time and break in for a few hours

Great sub for movies. It really pumps out the bass, I'm lucky I don't have close by neighbours. It's pretty big and heavy but delivery was still fast.

Superb Sub Bass

I bought this on the strength of online reviews, not something I would normally do without listening first, I held back on commenting, until the speaker had properly broken in, and I must say, I am not disappointed, blends in seamlessly with my KEF speakers, rich deep tone, no sudden "wham" and unlike some I have used, it did not take long to get the balance right, highly recommended and for the price out paces several for twice the money, if it has a down side, it is the size, its quite large, suits my room perfectly, but I can imagine it would not be as easy to accommodate for some people
