Fi Car Audio

The Q Series of subwoofers is our sound quality reference line. Featuring a hefty high strength single magnet motor structure with a heavily bumped t-yoke, the 28mm of Xmax allows for incredibly detailed, tight, and powerful bass. Triple progressive spiders keep the incredible linear excursion of this sub under control, while the extra heavy lead wire feeds the giant voice coil with a massive power rating of 1500 wrms. With technology pulled from the larger BTL line the new Q has more options than ever before. Hyper chamfer, full cooling, high or low Qts topologies, as well as the ability to add an inductance ring in the high Qts design, there is now even more flexibility within the Q platform. Working well in both small ported and sealed enclosures, you do not have to give up your trunk to have strong bottom octave foundation for the rest of your system.

The Q series is the new bottom octave benchmark for both Auto and Domestic applications.
