General Fi

Now, before anyone tells me to read about the options on the Fi site, I'm just letting everyone know I did that. So know that I got that out there, I'm putting a 15 BL in a '93 Saturn SW2 in 4.35cuft@32Hz, and I was wondering what options would be best for me? I will be using this setup for daily driving and I listen to ALL types of music. Right now, I would be feeding this thing 600 watts, but will definitely upgrade to 1000+ in the future. I'm thinking that I will get the cooling upgrade for sure, but I wasn't sure about the flatwind coils. The reason I say this is because I'll be using 8 gauge speaker wire and was wondering if that will fit in the normal coils with…

I been to the Fi site and looked through the specs for my BL 15 and found 1000 watts rms. Is that a starting point? Do the subs handle more power as you add features, or do they just handle the 1k better.

I WANT TO UPGRADE MY SUBS FROM BLS TO BTLS. THEYRE LIKE 3 MONTHS OLD. AMI S.O.L. OR DOES FI HAVE A PROGRAM. MIGHT BE A DUMB ? BUT MORE DUMBER (LOL) IF I DONT ASK ALSO WHO MAKES A GOOD 3 WAY COMP BESIDES FOCAL AND IS ANY ONE FAMILIAR WITH THE RD AUDIO COMPONENTS

FI WILL BE HERE...... WILL YOU?

i have a 2004 lincoln navigator and ive been doing research on a high out put alternator and im not sure with one to choose. so here it goes my choices are as follows; power master 220 amp, d.c. power 260 amp, xspower 250 amp and a 260amp Irragi Alternator i cant seem to locate 1 with a higher output should i go with 1 of these or should i go another route??? i have 2 15inch fully loaded btls on a lanzar opti 6000d and a lanzar opti 400x4hc ( for my loud speakers) and a kenwood for my tweeters. please advise and thanks in advance fellas!!!

anyone know if they ever got the magnets in for the btl's the 30 day lead time just ran out on my order and i wasnt sure what the deal is .

Hi, I have a FI 15 Q that needs to be rebuilt or re-coned because one of the voice coils is burned up. I am wanting to know if I sent the speaker in can they rebuild it as a BL or BTL, and how much would it cost?

Bought my sub second hand and need a recone. How do I tell the difference between '08 & '09 BL models. I have a 15".

whats the difference between the fi btl and the fi bl ?

what would be a good amp to put on one fully loaded 15 btl with dual 2 coils. i got a quantum 4500d that is stable at 1 ohm that i was thinking of putting on it but im not sure if i should do that or get a better one

i was reading and trying to understand the options on the btl and came across this Re: 0.7 Ohms/coil | 1.4 Ohms/coil does anyone know what this means???? thanks

i was wondering if anyone knows what option meade has on his 18" btl's. dual one or dual two ohm, spl or daily? thanks!

I have a 07 silverado crew cab and Im going to go with 1 12" downfire ported box. How do I know the size of the port Ill need? Also the amp I just bought is an sundown 1200d V2 Should I get a SSD with all the options or a BL with no options? Money is an issue, so if I will be fine with the SSD please let me know, keep in mind I would get all upgrades with the SSD

Album of Fi BTL 15 Pictures I have a Btl 15 fully loaded with Cooling, HiXm coil, Inner Heat Sink, daily Driver, dual 2s. I was recently looking at my sub and found that the spiders were starting to crack. I thought maybe the motor was bending the frame and causing the coils to scrape. I had a friend post on a forum about frames bending and they all said the frame would crack and break before it would bend. I do not know if I got a faulty frame or what but my frame is bent which made the sub not be centered and caused the coils to scrape on the motor and put extra force on that side of the spider . I have pictures and measurement to show what I am talking about. Also on…

I don't know very much about the x 12's and i was looking for some input. how do you guys think 4 x12's would sound in a tahoe with a ported box tuned at 30-32 hz with an epicenter? I will be running somewhere between 1500 to 2500 watts to them.

hi i'm an old guy, got a fi q15 on an saz 1500d in my suv. my son wants to go to sound comps, so i figured on getting another saz1500d to stap and getting a btl for the weekends. don't need to win but want to at least be competitive enough to keep his interest and make it worth the effort so how much difference will the average user find between the old 2 slug btl and the new 1 slug ? and is the difference enough that i realy should be looking for a one slug. i get that they booth are going to be crazy but on the meter does it matter that much ? i've heard pepole say it wasn't worth upgrading but i don't own either yet . thanks

how do i order a gasket with my recone ? and do recones ship same day ?

I hope that am in the right section for this post, if not, am sorry admin. I have been trying to post a drawing up so that i could get some feedback on it with no luck. Can someone steer me in the right direction. Thanks in advance for the help.

Hello, im making a box for my 15" Fi BL its gonna be 36 x 18 x 18 4.7 ft3 @ 30.5hrz daily driver just looking for some ground shaking fun : ) will this be a good box for that woofer?

Just as the title says, I'm looking at the best amp for my money to power my single SSD 18. Currently I will be using my 700W receiver as my amp untill I get a new amp for christmas. Sundown seems to be super duper popular, and apparently the best amps around. But the problem is that for the money, I won't be able to get 800W RMS if I go with sundown. I know its probably not recommended at all, but I found a Boss Audio amp rated at 750W RMS at 4 OHMS for $155. It didn't have any bad reviews from what I read. But I know boss audio doesn't really make quality products (at least from what I have read). Hopefully there is something better for the money. I really want to ths s…

I am gona put 2 18'' Fi Q in my truck. I am not sure what to buy as a amp should i buy like the sax3500 or 2 sax1500(or propose anything) And would i need a extra battery for that or its fine?

Just curious. As of right now for me, I ordered mine on sunday. Still haven't received any email yet other than order confirmation :/ I do realize today is the first business day though. I wonder what the quickest someone has received theirs is.

Meant to say single wall boxes but that just didn't happen i was too enthused at laughing about the basket making noise...even after all of that the sub still works.. Anyhow...keep your packaging. Don't send us this stuff back with a bunch of peanuts or anything in a single wall box and expect a 70 pound package to not be broken in 30 pieces.

Hello. I have 1 15" Fi BTL for now and I was looking at getting another in the future. I found a pretty good deal on an Ma audio HK4000D. My electrical will have the Big 3 done and I have 1 Kinetic 1400 battery but also soon to be at least one more. Would this amp be worth the money to push 2 15" Btl's daily (Rap) to their full potential or is it overrated?

Would it be better to get a fully loaded bl or q? Sundown says the new 1200 is capable of closer to 1400 given you have the electrical to back it up.
