Focal ISUB TWIN, passive subwoofers (pair)

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.
