Fi had this cutsheet for the stock BL18. A lot of cut sheets are available for the old drivers on the SSA forum under the Fi section! I pretty much just used this design and tweaked the layout for sub up port back and to only use 1 common wall for the port. Thoughts? The reason I used 7.0 cubes instead of 7.6 is because I'm going to invert my driver

I got my Fi custom 4inch BL18 recone kit in and installed!!! The new coil looks so much better than the old. The old coil was hanging way out of the top of the motor gap at rest. The new one is centered nicely in the motor. The spider pack looks awesome! My first time using CA glue sucked but hey got to start somewhere. ***Looking for input here or advice on how to push this thing to the limits. Strictly basslines centered around 30 hz I have no TS parameters yall but hypothetically... Imagine this style enclosure In a suburban with the sub facing up and port along bottom facing towards rear hatch is what I think I'm going to do. Attached is a rough draft of my idea. Obviously I'll double baffle but otherwise does the port area and stuff look good?

Hell yeah thank you KB I've seen you here forever. I went on Fb bassheads on budget but didn't know who to trust for a recone so i impulse went to Fi website and bought a recone for a BL and within like 6 hours I realized that coil wasn't no 3 inch and got to looking and thought oh shit 😆 I have to get with them immediately. I tried to call Fi just cause id rather do that but the number didn't work. I got them on FB messenger immediately. Idk who I got on the other end but they asked for my order# and pics and said "it is a BL with a 4inch coil very rare sub" I told them I'm on standby if they need any measurements or anything but no word yet. I Def don't want to bother them so I'm just on standby to wait my turn.

Thank you! I am super stoked to revive this thing, the guy here had it in a plywood box and the condition of it speaks volumes to the amount of care shown to this BAMF. They literally had no idea what they had. The paint is rustoleum gloss protective enamel. I thought it was to much orange so I polished it instead.

Has anyone ever had or know anything about an Fi BL18 with a 4 inch coil? Has 5 layer spider and what looks to be a flatwind coil 3 days ago I bought this one for 20 dollars! and am looking to recone it. But fi only has stock recones which should be 3 inch. Yesterday I impulse bought a recone for a BL 18 v2 d2 lol Then I cut the sub open and got to looking more and realized wtf I have a 4 inch coil! So I got with Fi, and they are helping me. But so far they have only said it's a rare sub.

Everything is OK as far as charging goes my truck charges mid 14s consistently. I will keep an eye on it. Today it wasn't hissing but the bulging is there

Hey my 2700d I noticed while checking my fuel pressure today it was hissing and I noticed the side bulging out. Please tell me that's normal lol

Maybe try running your idea past ram designs.. Is it possible get pretty loud in the mid to upper 20s on 1 sa12 ~600w?

Awesome man! I really like what my 2 e12s can do hopefully you can get where you want with this, and I'm sure if you do it'll be perfect. I assume these would be by far the best entry level budget woofers on the market.

I gotcha.. Their pretty resilient.. If i could I'd get a bigger amp rather than over driving lol. They sound good though don't they!?

My twelves do that, i smell a little something rarely. Ive had them for about a year now. Gains set at-10db I'm guessing some clipping is the case.
