Play nice

Music should be felt, not just heard. Our engineers have optimized the acoustic design to render stunning dynamics, deep bass and acoustic pressure in abundance.
Power at the tip of your fingertips,
so be nice.

Lyd & Bilde, Norway

"This is an excellent speaker system that doesn’t take up too much space and is easy to use and always sounds great. What more can you ask for?"
Verdict: Best Buy

Bass in our blood

Our focus since the beginning in 1978 has been better bass from small enclosures. The Addon Sub is no exception.

No nonsense design

Addon Sub follows our design ideals with a purist and simple approach.
The downfiring woofer makes this power cube subtle, yet outstanding.

Control the power

Power is nothing without control. The Addon Sub has variable crossover and you can shift phase for easier placement and adjustment to your room.

Initially there was a lot of power supply noise (50Hz) from the amplifier but after changing to the provided cable it is not so disturbing but you would expect the noise to be at zero level from such a well recognized manufacurer.


Tyylikäs ja hyvin soiva subbari. Subbarissa myös säätö namiskat josta pystyy säätämään subbarin äänentasoa ja volyymiä mieluisakseen.

Links in C10 by cable, suddenly all the hidden base comes to front.

Superb sound quality compliments T14’s really well. Knocks spots off my Bose speakers.
