About Q Acoustics:

  • Q Acoustics is a multi-award winning hi-fi brand, which was founded by experts in the audio industry with the sole aim of developing a highly successful loudspeaker brand.
  • It has been 10 years since Q Acoustics was founded, and in every year since we have continued to drive innovation and develop multi-award winning products.

Q Acoustics Story

  • Q Acoustics is not like most other loudspeaker companies.
  • Q Acoustics is a young brand. No heritage. No tradition. No old black and white photographs. We believe that to be the secret of our success.
  • Q Acoustics was established in 2006; but not by a wealthy music lover, hobbyist designer or retired rock musician.
  • No. Q Acoustics was founded by professional engineers and businessmen whose sole aim was to develop a highly successful best in class loudspeaker brand based on outstanding audio performance.
  • It’s that simple, a completely focussed understanding of acoustic engineering and inspirational design has driven our remarkable success.
  • We recognised that the only way Q Acoustics could possibly enjoy commercial success was to design and produce loudspeaker products that were, without question, superior to their similarly priced competitors.
  • So, with that aim in mind, for the last ten years with have enabled audiophiles around the world to enjoy Q Acoustics for its innovative and high performance loudspeakers.

Feature

  • Unusually at its price level, the Model 2070Si subwoofer is a completely DSP (Digital Signal Processing) driven system with highly efficient class D amplification.
  • However this has meant we have been able to achieve an advanced level of functionality, as well as optimising the sonic performance, by undertaking all filtering and limiting completely in the digital domain.
  • An example is the Speaker Type function switch, which alters the characteristic of the subwoofer's frequency response at the crossover point.
  • This allows the subwoofer to be optimised for use with either ported speakers, like the rest of the Q Acoustics range, or infinite baffle models.

The Powerful Bottom-End Performance

  • Unusually at its price level, the 2070Si subwoofer is a completely DSP (Digital Signal Processing) driven system with highly efficient Class D amplification.
  • This has meant we have been able to achieve an advanced level of functionality, as well as optimising the sonic performance, by undertaking all filtering and limiting completely in the digital domain.
  • An example is the 'Speaker Type' function switch, which alters the characteristic of the subwoofer's frequency response at the crossover point.
  • This allows the subwoofer to be optimised for use with either 'ported' speakers, like the rest of the Q Acoustics range, or infinite baffle models.

Twin Cones for Added Punch

  • Rather than using a single larger cone, the 2070Si Subwoofer uses two smaller ones, giving improved depth, delivering a punchier sound with more accurate timing.
  • The 2070Si is a ported, powered subwoofer with 2 x 170mm bass units driven by 140-watt amplifier.

Finishes & Installation

  • Available in Graphite, Walnut, Gloss Black and Gloss White, the 2070Si comes with carpet spikes for a solid stance or rubber feet for wooden or tiled floors, this clever Subwoofer is easily integrated into a new or existing HiFi systems.
  • It also boasts flush-mounted drive units curved edges for beautiful aesthetics and reduced diffraction.
