POWER8.2 8" 20cm 400w RMS Compact Subwoofer Unit With Integrated 12v 180w RMS Power Amplifier

World RRP: £171.99


Product code: POWER8.2

If you need to add bottom end bass performance but lack the necessary space then an under-seat enclosure is an excellent option. Just like our last under seat subwoofer unit, this carries the hallmarks of a quality product in this product market. A solid extruded and machine solid aluminium chassis and metal coned driver unit.The POWER8.2 is identical form factor to the POWER8.1 predecessor, but features the addition of 2 passive radiators mounted on the long sides. These help to extend the low frequency output and increase the overall efficiency of the cabinet. Which, in turn leads to a modest increase in overall system output.The unit features a bass remote on a 5M cable so you can make adjustments to the subwoofer output on the fly for those tune that deserve an extra whomp! The amp section features a LPF low pass filter, a subsonic filter and bass boost.This active speaker also has an auto turn on function which is used with the high level (speaker level) audio inputs. This enables you to integrate it into OEM systems much easier as the unit turns on with audio signal and back off when the signal stops, without the need for a 12v remote feed from an aftermarket head unit.

Version History

Prototype – We were initially going to make this the POWER8.1 V2 but so many significant differences led us to make it a new product entirely. V1 – Redesigned Power8.1 with more output and better amplifier from completely new facilty. Current model. V2 – We have found that we can shoe horn an event more powerful class D amp in that little chassis. This might also feature different passive radiators. Not built yet.
