Less than 20 days remaining to qualify for the Fi Audio Q18 Giveaway!

Don't miss this opportunity to win one of two customized Q18 drivers?

The Q Series of subwoofers is Fi Audio's sound quality reference line. Featuring a hefty double stack motor structure with a heavily bumped t-yoke, the 27mm of Xmax allows for incredibly detailed, tight, and powerful bass. Dual progressive spiders keep the incredible linear excursion of this sub under control, while the extra heavy lead wire feeds the giant voice coil. Working well in several different applications, the Q18 is the new bottom octave benchmark.
