Q Acoustics 2070Si Active Subwoofer (Graphite)

Great product, awesome design to me but a great price here in Belgium. I searched the web for reviews and a decent price for a quality subwoofer. 499 euros was a lot for a first sub for an entry range but decent first home cinema. And then there was Amazon.uk, : 2.38 times less price despite an amount for handling and shipping (well, its a 18 kilos sub). It works just perfect, an excellent bass: not too shaky, not to strong if you set it right. My set in a 18m² room: STR-DH790 and Eltax speakers. It adds the coherence to the whole, coherence I was looking for. I hope it will last long.

I had the choice between a pricy subwoofer here in Austria at a local store and this nice subwoofer sold by Amazon UK. All I can say - it was a great grab. In comparison with the other subwoofer, this one has a warm and hearty sound - nearly the English one from the 80s. It has a high level input and a line in for the sub out of an AV receiver as well, enough settings to adapt it to your room. Not cheap but worthy. Strongly recommended.

This is a definite improvement over my previous passive subwoofer. It seems to work well with my Onkyo AV receiver. It does take a little tweaking to get right but the controls allow for most people to maximise it's potential in whatever set-up it is part of. It is quite a long unit so it may not fit in easily in some home set-ups. It does produce good tight bass sounds and has enough rumble for movies. I don't really use this for music, mainly for movie soundtracks, so can't really comment on its performance, though I suspect it would do very well for music too.

Quality product, bought to replace another well known brand sub. Significant improvement - tighter more controlled & musical bass on musical soundtrack parts but also plenty of percussive attack & rumble when the action starts. It’s also a fairly slim and relatively discreet unit (we have ours tucked underneath a side table) No hesitation in recommending to other potential buyers.

excellent sub for the money,very responsive,keep up with the fastest of action and excellent for music.The range of base is superb down to deep enough to vibrate the floor to a nice rolling base from highs to lows.

Would of been a good product if it worked !

I've had the Q Acoustics 3020i bookshelf speakers for almost three years and am still very impressed with the sound quality. I purchased this sub to add a bit more bass to music and improve the low frequency end of my Hi-Fi setup. The difference in sound is incredible! Once set up properly (easy to do), the sub drastically improved the sound from my setup. Music has much more depth and movies have more punch. Highly recommended.

Larger in the flesh than in photos but given time does produce the extension to the frequency range on my Hi Fi I was looking for as domestic considerations dictate smaller main speakers than in the past. Setting the levels for the optimum took some time and listening to a variety of music types and source (I still use vinyl as well as CD). I found less was better and had the volume setting lower than the suggested startpoint with the crossover at slightly lower than the -3dB lower frequency of my speakers worked for me. Properly set up I really do not know the unit is there and can listen to the music BUT it did take a week of tweaking to get to this. I would guess that home cinema set up would be less demanding than a Hi Fi set up and I was partnering it with a different make of amplifier.
