Focal

Focal's Auditor Series R-250S subwoofer is an excellent choice if you're upgrading your system on a budget. Paired with Auditor Series coaxial or component speakers, you won't spend too much cash, but your new listening experience will make you feel like a millionaire. This sub's durable polypropylene cone and butyl rubber surround will endure the ravages of heavy bass output, while delivering powerfully precise low notes, thump after thickety-thump. Focal used a special design that maximizes ventilation inside the sub so that heat is properly dispersed during extended use. Match this sub with a sealed or ported enclosure, feed it up to 250 watts RMS, and you'll be bass rich for years to come.
