Focal ISUB TWIN

The pair of ultra-compact ISUB TWIN passive subwoofers is an innovative solution that considerably increases the bass impact of an in-car audio system, all this without any loss of space in the interior or trunk.  These boxes simply slide under the seats of almost any vehicle and can be fixed directly with the velcros provided or screwed into the floor. We recommend to power these boxes with the Impulse 4.320 amplifier, whose two front channels will remain available to connect a pair of speakers in the front doors for example.

When developing the ISUB TWIN, the Focal engineers focused on compactness without compromising high-performance. Measuring only 3 1/8” (8cm) high, the subwoofers can be comfortably slid under a seat. They are therefore extremely easy to install, without taking up any space in the cabin or boot. As for performance, the speaker drivers have been specially designed for these subwoofers, delivering high-fidelity sound and incredible power handling.

In order to get the best of your ISUB TWIN speakers, a running-in period must be respected to ensure they are ready for this. We recommend that, once the system is ready for listening, the drive units should be run-in with medium volume setting, with music that has the full bandwidth of frequencies (sub-bass through treble). This running-in period should last for a few weeks, to gain the full potential. After which the excellent performance of your ISUB TWIN kit can be fully appreciated.

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.
