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.

Have one BL 12. It sounds very good and really gets down for one 12. Couldn't be happier. Customer service was excellent as well. Thanks Nick.

I bought a 12" BL fully loaded and I have to say WoW! Just one, when I told my friends they thought I had 4 12's. I got it with a RF 1200.1D @1 ohm. You will not be disappointed! Fi 4 life. Lol

I have (1) Fi BL 12 (no options) pushed by a Planet Audio BB4000.1 in my crew cab Silverado. I am assuming the amp is providing around 2000 - 2200 watts at one ohm to the sub in a 2.2 ft^3 box @ 33 hz (under the seat.. barely!). This thing absolutely SLAMS and is very musical! Great job Fi, you'll get my money again!

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.

Very surprised on how stiff suspension was sub hits clean and hard just took long time to received sub would like to see better updates on status of shipment said sub just shipped 2 weeks after sub was delivered
