About the Focal Sub 12 Slim

Bob Bihlmayer

Easy to fit

Focal has long been renowned for the quality of their speakers, and our customers agree — they consistently give their subs excellent ratings. Now they've brought their expertise to the popular shallow-mount category of subs. The Sub 12 Slim subwoofer delivers the solid performance you expect from Focal while fitting smaller enclosures to give you more installation options.

Bulit to deliver

The Sub 12 Slim's polypropylene cone and butyl rubber surround handle up to 280 watts RMS with ease, with a vented steel basket that helps dissipate heat buildup when things are running hot. This sub is designed for use with sealed enclosures, and its 4-ohm impedance makes it a good match for most systems. You can add stylish protection to your sub with Focal's specially-designed 12" grille (sold separately).
