The subwoofers that moves the masses while taking home championships for the demanding user.
From being our entry level back in 2012, the IS subwoofers have now left their teens behind and are now fully grown up drivers with a proud heritage.
On the third revision of the IS series, they now offer more of all. Apart from same type of cone material, this generation of IS series is a completely new woofer with features found in High End drivers, regardless of SQ or SPL. The cast aluminum basket offers great airflow, ensuring the newly designed voicecoil is kept cooler than before.
The new motor now has a ventilated pole which features XD flow, (X-Drilled) which cools the voice coils from the inside of the bobbin which will increase the powerhandling.
A total proven increase of 25% (now 750 watts) compared to earlier models, they are now catering to both bassheads with the urge to demo for long periods of time,
but also to the audiophile purists that need premium components in their systems.

*It is essential that our subwoofers are given time to allow the suspension to soften up. Depending on use, this may take several weeks. While this process is undergoing, it is not recommended to apply full amplification power according to the subwoofers specs. Once the moving parts have been broken in, the performance of your subwoofer will increase.
