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.

Phenominal, crisp, clean, smooth, can hit every note I throw at it. It is a great subwoofer and I womt get anything else but Fi now, it took a month to get it too me. But it was DEFINITLEY worth the wait. Not a single complaint or con that I can give this sub. I was looking at jl audio, kicker, sundown, mtx, orion, lanzar. When all an all came down to it. I new I made the right the decision and I'm blown away by this subwoofer. Just buy it.

I have saw the reviews, watched the vids on YouTube. So I had to try one. I have a fi q 12 dual 2 ohm powered by a Rf T 10001bd in a 2 cu ft ported box tuned to 33 hz in reg cab gmc sierra. The lows are killer and the SQ of this sub is amazing! By far the best sounding sub I have ever heard. I'm a big fan of the lows....and this sub put them out!!!! Fi, this is a great product!

With my fi Q 12(d2ohm, cooling, p camfer, heat ring) i hit every low note there is. Not only it hits every note but even in a ported box(mine is 2.0cu.ft.) it gives tight bass. Sound quality is much better than pioneer kicker alpine mtx and other mainstream products with the proper settings on the amp and radio so you wont have gaps in frequency response. Wait time was 1 month but as many said and i didn't believe, it's really worth it. Since i live in Canada i was worried that the surround material would freeze but not with this one. Amazing loud sound, i love it!!
On the down part, i expected some screws with the sub.

I just bought 2 fi Q's with D1, high qts, and heat ring because I already had a sealed box I designed for my trunk. I am using a Rockford Fosgate T2500-1bd.I was impressed by the SQ but not as loud as I wanted. So I built a custom box. 2.1 cu. ft. tuned @33Hz. I was unsure how they would work being high Qts designed for sealed but they work wonderfully! The roof on my 2012 Dodge Charger flexes over an inch and you can feel it in your bones. I would recommend fi to anybody. These subs are quality built and I love the flat wound coil design the subs never smell or feel hot. So worth the money.

Hands down the best subwoofer I have owned so far. The Q12 has such tight bass, but gets rowdy as well. Hats off to Fi Car audio, bravo!

Sounds very clean. Comparing it to a Jl w3, its in a different ballpark in terms of SQ. I would recommend this product.

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!
