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 had gotten my second FI BL 12 in the mail and I had gotten it in three weeks. I have them running off an alpine mrx m240 @ 2800 RMS and I must say that it was above my expectations, I get about a 1-1.5" flex off my roof and a free vibrating chair. If you are on the edge of getting one, do it. It is worth it and you get what you pay for in this type of game. thanks a lot FI I recommend you to everyone

When I got my fully loaded Fi BL 12" Dual 2ohm in the mail, I could not stop grinning. The new carbon fiber dust caps looked amazing on an already amazing looking product! Once installed I was immediately impressed with the SQ and it's accuracy to each bass note especially the bass notes in quick succession. This driver has brought out all kinds of bass hits that I never knew existed in the songs I'm most used to!!! After I had it warmed up a bit I kicked in some lows and my car started flexing like a crazed body builder! ALL in ALL this BL from Fi is AMAZING! I will be back for more!
Thank You Fi Audio!

Ordered two FI BL fully load and I am loving them.

Ordering had a little trouble but understandable because of the holidays they even got back to me over the holidays and they came right in time for my wife's birthday they were for her. These subs take anything i need bigger amps to power them. They are beautifully made clean love the look. Hit hard and they are only half way powered and the whole neighborhood hears em. lol. will definitely buying more for all other vehicles including mine and i know others just from hearing these will be buying them too.

Got this in the mail after a month wait for shipping, but once I go it I already had my ported box tuned to 32hz ready. Screwed it strait to the box and hooked it up to my Hinfonics brutus 1600.1 and Ran my dvc 2 ohm bl 12" to 1 ohm and set my gain at 3/4. So I was probably giving the sub straight out the box new a solid 1300RMS and it held every bit of it very well. I noticed the flex is very nice and it keeps a variety of music quality. This thing can probably take more then 1,500RMS but I wouldn't risk it. All in All, this is the best 12" sub I've ever had, worth every penny!

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
