Focal ISUB TWIN Ultra-compact, passive bass enclosures

POWERFUL, HIGH-IMPACT BASS

Ultra-compact, passive bass enclosures

The pair of ISUB TWIN passive subwoofers drastically improves the impact of the bass in an in-car audio installation, specifically thanks to the double ferrite speaker drivers and heavy-duty, tough aluminium cone. The front grilles promote optimum sound dispersion throughout the cabin.
These ultra-compact subwoofers are quick and easy to install too, without any car modifications required. They slide comfortably underneath the seats* and are super easy to attach, with no tools required, using the self-adhesive strips provided. However, it is also very easy to screw them to the floor if you so wish.
We recommend powering the ISUB TWIN with amplifier Impulse 4.320, its two front channels will remain available to connect a pair of speaker drivers in the front doors, for example.

For powerful, high-impact in-car bass, Focal has developed the ultra-compact, twin subwoofers ISUB TWIN. Easy to install under a seat and delivers outstanding performance, the twin subwoofers complement any on-board installation.
