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 sub. It was either this or going with JL. Im so happy I went with fi. I was getting tired of my old sub shaking everything and hurting my ears. I put this sub in and all i drive around smiling like a school girl who just got laid for the first time. This sub plays notes i didnt know were there. It plays everthing. I wish i could just put the feeling i get from this sub in this space instead of words. This sub is amazing. I have it in a sealed box and compared to the last one, its all the noise and power with out shaking my eyeballs. If i had the room in my car, I would buy another one right now.

Got the loaded Q 12s and have them eating 2400 watts without issue. Incredibly clean, clear bass. Powerful woofers, not spl applications but definitely high Sq. No regrets whatsoever!!! Thank you Fi!

I told my friend to find me some subs. He found me the Fi Q12s. I could not be more happy!

this is by far the most impressive speaker i have ever seen. the construction is amazing, and completely solid. sound is amazing. so glad i found the guys at FI, the build and ship time was worth the wait. I will be buying more. And the guys at FI and shawn, high five men, hands down best customer service. quick email responses, very helpful

I've had some good woofers in the past but the Q is phenomenal! I've got a single wired 1 ohm with a Sun Down SAZ-1500D V3 and absolutely love it!

While the mainstream brands are cranking out subs that cost of similar prices that are cheap junk made and in china, FI Audio keeps the dreams of affordable audio (relatively speaking of course). I had a Fi Q 12 for almost 2 years before selling it, the amp pushing it wasn't superpowerful but the sub is very efficient being able to bang even under lower power settings, I wish I could have seen what it could have done when powered by a proper amp. Don't give corporate America your money for cheap junk, go independent and support those who truly care and are enthusiastic about car audio.

Just one of these things broke my rearview mirror in my single cab dodge on a 2000 watt mono block.. I'll never buy another sub again!

I own 4 Fi Qs (cooling option and internal leads) in a sealed box 1.5 cubic feet for each chamber, in my 2002 Honda accord. on 2 crescendo BC2000D and let me tell you every where i go i make people head turn. whenever i go to my girlfriends apartment she lives on the 3 floor and she tells me i make the glass stuff in her kitchen and the picture on the walls vibrate. that's how she can tell that I'm outside. even though these are SQ subwoofers they still pack a punch in the SPL department. i love my Qs and i wouldn't give them up for anything. check me out on youtube: 954cityofdahood i haven't upload any new videos yet but i will soon

I currently have this sub running on a 1700 watt RMS amplifier in a ported box that is way too small (dual 12 custom box on the way) and it is amazing! Right out of the box, i knew i had a quality product on my hands - heck, the thing weighs almost 50lbs! i listen to all types of music from jazz to hip hop to rock n roll to reggae and let me tell you, this thing has NEVER missed a beat - i now hear kick drums and bass guitar lines in my tracks that make me think im listening to it live! The sound quality is truly amazing! Ive had mine for about a year and it has never gotten too hot or smelled - even during extended periods of full power operation from hours of demos. Now, i added the cooling and spider options so those probably helped... By the way, if you are worried about it "not being loud cause its a SQ woofer" dont be! Mine has held its own in a competition with two 15s. (granted they were low end models, but still!) All in all, if you buy this woofer, you will not be disappointed!
