first question: What would be the smallest enclosure you all would reccommend for two fully loaded 18" BTLs seeing about 3500watts(rms)/sub, tuned to the low/mid 30s and mainly for daily driving (with maybe the occassional competition)? second question: i know on your site it says the btl comes in a 10" size, but i thought i remember some problems with it so you all quit making them as 10s. im basically wanting to know if u all still make a 10" BTL that is built for pure spl? thanks, andy mods: u can move this to the FI technical section if u want...didnt know where to put it.

im new to this site and reading posts fi can recone a majority of drivers. so my question is can fi recone a elevation audio x15 drivers. not their current execution woofers but the original ones with the aluminum cones. the motor uses a 3" vc and i want to reuse the execution motor with a fi basket and recone kit. i have 2 which are taking up space in my room 1 still plays but is on the way out and the other one is frozen. so get back asap thanks alot

15" Q on a old school memphis 1000D, quality was alot better before youtube but then again tis my first vid

Hey guys, I've been lurking these forums for a few days now and I guess its about time to post. I just got a brand new mazda 3 hatchback and I'm looking to upgrade the stock sound system with a sub and amp. My budget for an amp and sub is gonna be about $500 but I can stretch it to $600 if absolutely necessary. I've been reading the forums and am currently leaning towards running either a 10" or 12" Fi Q in a sealed box in order to save trunk space. I listen mainly to rap and hip hop but I also listen to some rock like radiohead, chili peppers, and rage against the machine. Basically my goals are to get a good SQ type sub that will add a good low end sound to rock s…

Im looking at purchasing two BTL15's and I'm leaning toward the Sundown amps. The SAZ-3000D is rated at 3000RMS and I've read that it's underated at that. Is this amp too much for a fully loaded BTL15. I plan on strapping two 3000D's to two BTL15's at 2ohms which should be 3000w per sub.

Looking for a few parts... tinsil lead, 2 15" gaskets, 4 sub terminals(with screws on the side). Any chance i could get them from fi?

just wondering if anyone is running a lot of power to their ssd's? and by a lot i mean 1000 watts or more......if so, how much power were/are you running to them and how do the subs take it? Just wondering cuz I've been having some financial issues and may not be able to do the monster system i planned to do this season.....I'd like to try and do the 149 class with 4 x 15in SSD's without a wall...

Not really rantin, but have been waiting 2 weeks to get my tax check. I was getting ready to order 2 BTL 15's today and i noticed the price WAS 898.00 the last time i checked, now it's 983 because of 85 dollars in shipping, so now i got to wait till wednesday to get back to the bank. When did fi quit offering free shipping? It had to have been within the past week?

Hello, i am wondering if FI car audio can sell me a voice coil. I have all the neccessary parts for my 15" dayton audio MK3 recone but the vc. pierceaudioproducts sent me the wrong one, and when i reordered they didnt get it in. anyway the simpl specs are 2.5" diameter, 3" height, 2" winding, Dual 4 ohm impedience. i would also be fine with single as long as it is powerfull. I emailed FI but i havnt recieved a reply yet, so i thought i would try here. I am trying to get the caliper measurements for it. ALSO, i have various 2.5" voice coils and various spiders, baskets, etc., if anyone is intersested please say so. Thanks

I am due to receive my ups delivery of my 12" Fi Q's tomorrow and i cant wait. i am so impatient. i want some advice on how to properly break these subs in because i have never learned the proper way. with any other subs i had i just installed them correctly (properly set gains and what not) and then proceded to see what the can do. i have been addicted to car audio for some time now but i am always learning something new. any opinions/advice will be greatly appriciated. running a Rockford fosgate 2000.1 amp if anyone is wondering.

i just wanted to know before i ordered, is the cooling option important to add to the 15"btl for a daily sub?

I havent powered my subs up yet, nor have the been mounted. They've been sitting in the boxes they came in since I got them last year as a present from my gf. Not dropped or anything like that, its weird I've never seen anything like it. I pulled one out to show a buddy of mine the sheer size and outstanding build quality. While doing so, I noticed a crack in the magnet. Not a small crack either, it goes horizontally, all the way around the sub. And it wasnt there when I got them. I've emailed Scott, but I would like to see what you guys think. I'm a little concerned. And I was planning on inverting them, cause they have a very sexy ass. Here are a pictures of the crack: …

I've emailed a few times about getting a recone but I've never got a response. Can anyone help me?

Hi, is there anyone in charge that can look up to see where my sub is in the delivery world? Theres no phone number to call them

What does rescheduled to 3/7/2007 mean? Is that when I can expect it. UPS is showing my sub as rescheduled to 3/7/2007.

I have 4 Q15's ported in 10ft^3 tuned to 32hz on a IA40.1 @ .5 ohms. I am hitting 152db on a TL and 159.6db on AC mics, but I have it tuned for music and I feel the Q's are much more powerful down low. I compete locally for fun in unsanctioned events and have a nice lil collection of trophies. So this past Sunday, a local but large Car Club asked me to join up, because they want an SPL division for SBN and whatnot, and they have and audio shop on board to help with builds. So I agreed, but know that I need to do better then 152 on a TL to have a chance in an "official" comp. I have only a 140 amp alt, but I have 2 batts for my electrical and the IA 40.1. Max box ~10cube…

if you had the choice what would you take 2 12" ssd's getting 600 watts each or a 15" Q getting 1200 watts. Both would be in optimum enclosures tuned around 32HZ. I want it to be loud and be able to hit the lows and sound good while doing it.

I'm upgrading from fully a loaded bl to fully loaded btl (d2) This is my (Soon To Come) setup is it good or not? SUB:(1) 18'' Fi.BTL (Fully Loaded) AMP:(1) AudioQue 3500D (3500 Rms @ 1 Ohm!! & BTL's are recommended @ 2000 Rms) [is the amp good or what?] its getting the whole 3500 rms http://www.audioque.com/aq/AQ3500D.htm http://www.audioque.com/aq/images/AQ3500D/AQ3500Dguts.jpg (4) Screws for terminals (Better solid connection no leaks) Enclosure:(1) [Ported] 6 Cuft. (After displacemant) Tuned to 32hz. maybe 3/4 MDF Thats my setup but my main question is how much of a db differnce is a enclosure thats tuned to 32hz. from a enclosure thats tuned to 34hz. I love …

I'm looking at 2 used 15" BL's owed by 2 different people. Both are D1's and both are Fully Loaded Daily Subs However, I've been told that 1 has the older style double stacked mag and the other has an identical sized single mag. Did they change the mag design? And if so, will these subs perform differently from one another making them not so good as a pair?

I have one and have some questions, wondering if you are familiar with them, I cant find much info on them on the net, google has faild me , anyway, if you do could you respond?

What is the weight of a standard BTL 15? Thanks.

just want opinions what do most of you guys use? I have them wired with 12 guage right now. Was wondering if it would really make any differance if i used 10 or 8 guage or would the 12 be fine?

Just bought a SSD 15 with copper coil. Had it for about 3 weeks before i was able to give it some real power. Originally i had it on about 250 watts, and it sounded very well for that. I was surprised really. So then i match it with a good partner, hifonics 1608d Hooked everything up and man did that sub slam. I gave it all of its 800rms and then some. And it still wanted MORE! Played very very nice, the more power i gave it up to its power handling the better the SQ got for me. I didn't completely turn up my amp but everything i threw at the SSD it took it with pleasure, it handled everything nicely and as much as i turned the gain up there was no distortion at all…

Just curious if there's a reason the Fi Q series isn't showing up on the website...Either way, could someone possibly give me the specs on the 12" sub. I need the detailed specs so I can input the sub on WinISD to attempt a box design.

Sooo...Didn't realize that this is recommended as a minimum(not sure why its not included then) and I would have gladly paid the 10 bucks to add this.... But I didn't know.. Anyways, What do I have to worry about without this?
