Q Acoustics 2070Si Subwoofer Gloss White. This dynamic, twin driver, active subwoofer boasts a powerful 140 watt amplifier driving 2x 170mm long throw bass unit. It provides a solid and compelling low frequency performance.
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 subwoofer's twin 170mm bespoke drive units are driven by two matched mono power amplifiers, producing a combined 140 watts.
However the switched mode power supply consumes a mere 2 watts when in 'Standby' mode.
