Active sub cabinet with 8" (20cm) reinforced driver and internal amplifier with active filter circuit.

Inputs are on twin RCA or from a stereo amplifier on spring terminals (between amp and mid-top speakers).

Cutoff frequency and Gain rotary controls can be adjusted as required. "Auto Off" function deactivates the amplifier when no incoming signal is detected to conserve energy.


  • Integral amplifier with variable crossover
  • Auto off function conserves energy
  • Speaker level or line level inputs 


As most of our systems do not feature a pre-out or subwoofer out it's previously not been possible to connect the majority of subwoofers available on the market.

For the first time you can now add deep bass to your installed home audio system with our 8" active subwoofer!

Simply connect the subwoofer via speaker cable in line with your ceiling speakers to completely transform your system with deep lows and richer sounding music.

The subwoofer is completely adjustable in volume and frequency so you can tune it to your preferences, whether you want to add a bit of subtle depth, or if you want room shuddering bass!

This low cost add-on will help create the ultimate installed home audio system without breaking the bank!
