Focal Inside ISUB TWIN Ultra-Compact Passive Subwoofer

This is the Focal Inside ISUB TWIN Ultra-Compact Passive Subwoofer,

The pair of ISUB TWIN passive subwoofers considerably increases the bass impact of an on-board audio installation, in particular thanks to the heavy and robust double ferrite and aluminum diaphragm speakers. The front grilles promote optimized sound dispersion in the passenger compartment. The installation of these ultra-compact boxes is simple and quick, without modification to the vehicle. They slide easily under the seats* and attach very simply, without tools, using the hook-and-loop straps provided. However, it is very easy to screw them into the floor if you wish. We recommend powering the ISUB TWIN with the Impulse 4.320 amplifier, two channels of which will remain available to connect a pair of speakers in the front doors for example.
