Need an affordable subwoofer which matches the expensive standards?

Q Acoustics is an independent British company established in 2006 which manufactures loudspeakers. They are known to design and produce high quality speakers at a very affordable rate. Their range of products has had outstanding success and has a genuine appealing sound.  The Q Acoustics 2070Si subwoofer has been designed to match the award winning 2000i series; hence reviewers and users alike had high hopes from this piece.

The Q Acoustics 2070Si has two 17cm drivers, each driven by a highly efficient mono class D amplifier. It has a power output of 140 watts, enabling it to produce powerful songs. With the improvements from its previous award winning versions which include a 25mm tweeter, new crossovers and a different cone material; carbon fibre and ceramic coated paper cone, its bass extension is precise and highly effective. Weighing about 15kgs, the 2070Si is available in a tall, slender design in black, walnut, gloss white or black.

As a part of the new ‘i’ range this speaker is a fully Digital Signal Processing (DSP) driven system which ensures highly optimised sound results. It is rare for a subwoofer of a price of £275 to offer this feature. The Q Acoustics 2070Si Subwoofer features power, volume and a crossover control. The crossover control allows the subwoofer to alter its frequency response (50 Hz – 150 Hz) and optimises it to function with ported speakers like the Q Acoustic range or other models.

The 2070Si has a 2 years warranty which can be redeemed at any authorised Q Acoustics retailer. With its precise bass extension, the new Q Acoustics 2070Si is a valuable addition to a home theatre system as well as two-channel music. The device can be used with Q Acoustic 2010i, Q Acoustics 2020i, Q Acoustics 2050i, Q Acoustics 2000Ci or any other high quality speakers.

 

2070Si is a powerful subwoofer which will add extra low-frequency weight to your movies and music, making them hugely entertaining and more realistic.


Well made and sounds perfect. doesnt exaggerate any part of the frequency range.


Best Q Accoustic sonic performance ever.


Completed my home cinema system with the superb Q Acoustics 2070Si subwoofer and really felt the difference in both films and music.

    Very nice subwoofer for the price. Sounds like it goes down to like 25-30hz but it says 50hz here.
