The BL Series fills the gap between the all out SPL monster and a solid daily driver. Featuring a chamfered solid pole piece and standard double stack motor structure with 8.660" magnets as the foundation for a truly tough subwoofer, you can choose from a variety of options to custom tailor the sub for your exact application. With the addition of the hyper chamfer, or our patent pending heli-cooling channels along with the Daily option, you can bump up the subs thermal capacity for long term daily driving abuse. Looking for an ultra tough SPL sub? Choose the SPL option, one of the 8 layer aluminum flatwind voicecoils, add power, and let it rip. With head cracking upper bass and brutal low end, the BL handles the extremes with ease.

I was exceptionally pleased with the customer service and FI audio did a phenomenal job getting my 12" bl out as quickly as they could and it was at my house within a week. Thank you guys for the superior quality and exceptional customer service.

Wow. I installed this in a center console sub box i made in my truck, and its wired at 1ohm, getting only 1100w rms and within the first 5 minutes my door could barely close. The back of my cab flexes, and everything in my truck is shaking. Can't even imagine 1500rms in my truck. Mind=Blown

I had gotten an Fi bl 12 and I must say it is everything every one writes about. The sq is superb and the spl is unreal. It shakes everything in my 03 vue and the roof dances on 30hz like I've never seen before. Loudest single 12 I've ever heard. beats the alpine type r, kicker l7 15, rockford ect. Thanks for everything Fi. :D

went from 2 12" rockford p3's (loud as fuck for only paying 250) on my t1500 rockford amp to one of these and i will say on some songs, not many at all, the p3's hit the mid 40 hz's a little louder( due to box tuning). but that is two subs with the same power vs one. but man.. on the lows, this subs does some work. everything flexes in my taurus. windsheild had a crack in it.. now multiple cracks lol. waited only a month for the sub and that was with the 4th of july going on. would defiantly buy again. love this subs and sounds amazing..

These subs can take the heat. Literally! What separates Fi from other subs I've owned is that they can really stand up to high heat (around 175 degrees est.) They don't alway get hot but when they do, don't worry too much they can handle it. I've got mine on a Rockford T1500bd @ 1ohm roughly 1700w RMS. My windshield on my 06 GLI is slowly but surly shattering... no joke.

Purchased one may 20the received June 20the the wait will kill you but man it's worth it looking to order a second one this weekend. Sub isn't broken in yet but damn it gets loud. I recently had two Cvx 12s CDs play bass on plus 1 the Fi shits on them good. Fi is on negative 16 on my pioneer deck got windshield fkex bumper flex door flex so alkaline I can say is buy one. Running the sub on a Rockford 1500.1bdcp I have two of them amps just waiting on a second sub. Amps birth sheets are around 1900 both. So Yea 3600 to 3800 rms should be perfect in a small civic!

I had an IDmax 12" sub and it blew.
This sub is way louder and deeper.

The subwoofer is loud and is clear sounding quality. The problem i have with the sub is that it doesn't have enough suspension travel. I think the speaker would be much louder if it did have more travel. One other thing, and its not that nig of a deal, is the spider needs to have at least one more layer. Other than that it holds power well and sounds good awesome speaker for the money.

I thought i would try fi audio after years of name shopping. I tried the dc audio subwoofers but they dont have nothing on fi audio. My two 12" bl's are the best subs i have ever owned. Purely amazing sound and quality with mind blowning spl....thanks you fi audio
