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 27mm 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 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.

I love this thing I've got it in a ext cab ranger being pushed by a crescendo amp and it slams but it also has a huge range for being such a big sub thinking about getting two very pleased don't think just buy it!!!

I got mine a few weeks ago with all options but High QTS and Heat ring.
It is running on 700wrms in a tiny 2cuft sealed box right now, and while it is being broken in I can still feel the lower HZ. Playing heavy black/grind metal the thing doesnt miss a note.
Sounding better than any others I've heard in person so far.

This sub is one of the loudest low hitting subs that I have heard I have it in a box tuned to 30hz and the lows make my trunk go crazy I love this
