Focal RSB300 Auditor Series 12" 600w dual 4-ohm voice coil component subwoofer

Affordable quality

Focal has built a reputation for building great speakers for home, car, or recording studio, and our customers definitely give their subs high marks. Their Auditor Series RSB-300 12" subwoofer delivers impressive bass, maintaining accuracy even when you're pushing your system hard. The sub's two voice coils allow you to wire it for 2- or 8-ohm impedance, giving you more flexibility when you expand your bass setup.

Built to take it

The RSB-300 features a polypropylene cone with a butyl rubber surround that's made to handle up to 300 watts RMS. Large vents in the sub's steel basket help dissipate the heat generated by extended bass sessions. This Focal fits into just about any kind of system, whether you prefer tight bass from a sealed box or fatter bass from a ported enclosure.

To drive this single subwoofer, we recommend a mono amplifier rated between 225 and 450 watts RMS at 2 ohms. For more information.
