SUB12 ACTIVE SUBWOOFER

The Image sub10 and sub12 active subwoofers are both optimised to reproduce the lowest octaves accurately and blend seamlessly with Image floor standing and bookshelf models. With more than 200 watts RMS available in both models there is more than enough power for any domestic application.

Both systems employ a passive radiator (opposite the motorised driver) that has a critical mass to control driver movement at resonance and then extend the bass response below audibility.

The unique characteristics of both Image subwoofer drivers allow them to be used in small enclosures, producing controlled extension in your listening room to 25Hz and below. They will fulfil every demand for deep clean bass reproduction from the latest digital surround sound sources and will also be totally at home in the most demanding High-end audio system.

For small to medium rooms we recommend the sub10 and for larger rooms we recommend the sub12. For the ultimate system, consider using one sub10 each channel to partner your main speakers.

Wiring either subwoofer to your system is very easy and you can choose high level (speaker) or low level (RCA) inputs.

Facilities include:

  • Active and variable Low pass crossover from 50-100Hz to add the lowest octaves seamlessly to your main speakers
  • Variable subwoofer amplifier gain (volume) control to match the subwoofer output to your main speakers
  • Crossover on/off switch so you can choose to use the crossover within a surround sound processor rather than the crossover within the Image sub10 or sub12
  • Phase reverse switch to align your main speaker phase with the subwoofer driver
  • Auto Standby that deactivates the amplifier to save power when no signal is present
  • Thermal overload protection to prevent the subwoofer amplifier overheating if overpowered
  • Gold plated input and output connectors for perfect signal transfer.
