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've had my Bl12 for a few months now in a 2.5cuft box tuned to 30hz with only 1200w rms going to it and this thing POUNDS the lows. I never thought a single 12 could do what this thing does every day. My fully dynamat'd trunk stands no chance against the rumbles this thing makes. Fi customer for life!

Best sub I have ever paid for so far. I was a little skeptical at first. Now I realize why it takes so long to ship. You can't have subs like that on standby. It really slams. We'll worth the wait. I will be buying 2 more later.

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!
