What have you found to be a "sweet spot" for your 12" Q??! i'm running a SAE 1000D to it at 1 ohm. with BP option. i'm looking for both sealed and ported enclosure sweet spots. share your views here. by sweet spot i'm talking about where it makes you jizz when you hear it. come on don't hold back. i want it to be loud, but clean and tight, just like our women!.. well with the exception of the loudness, thats no good with the ladies lets hear it!

not trying to be a pain but are the specs going to be posted anytime soon.i know the specs say they are a sealed sub but everyone knows how well they perform ported now they have been out for a while.

Would 1 10" bl with cooling and flatwind coil in a 1.4 cuft box tuned to 32hz be louder than 2 10" ssds in a 1.8 cuft Tuned to 33hz? Also what would be the ideal port area for the ssds if I put them in a box with two ports? Thanks

i came up on a deal. both subs are 15" BL's, both have cooling, flatwind, and the daily option. 1 however has extreme leads, and the other has regular leads. will this cause problems between the drivers or is it ok to run them together? i know the extremem leads can cause slapping, but is that the only downfall?

I want to get a btl 12" dual 2 for my gp3000d pro amp. I just don't know if it is recommended to get the 3rd magnet and HiXMcoil options. please help asap. thanks!

ive had a fi x 12 for a while now in a standard ported box i built. i want to spice it up a little by building a 4th order bandpass. Problem is i dont know the calculations for it. If someone could give me a hand in this it would be much appreciated. iw ould like to tune it to 35. if not that than 40.

Would a 15" Q dual2 work decently in a 2.3 cubic foot @ 30hz enclosure? Would having a driver in a smaller ported box offer the same benifit as having it in a smaller sealed box as in increasing its power handling? As I have a USAmps MD.1D which is rated at 1200@1ohm but I believe it is slightly underrated.

Hey guys it's been a while since I've posted on here and I just wanted to know what yall think. I've got a 2nd generation BTL and I'm thinking about selling it and upgrading. Which would be louder 2 BTL's or 4 X's both scenarios would be 15's? I know the more the surface area the louder but would the power make any difference in the application. Any suggestions would be helpful. Thanks

Hi guys ! I was wondeering if can all help me out.. I purshased 2 12' Fibtl Fully loaded and after all I descided to try on with 1 first . I hoocked it up to a Hifonics Colossus XXV and wired it a 1ohm ...after like 5 minutes of playing time...the sub was working on and off. To me it looks like when it gets warmed up the sub completly stops working...but if I leave it cool off..it will work for a minimal amount of time. My amps never lost power and always stayed on. Do you guys think I blew the sub ??? or should I try to rewire the sub to a higher ohm ??? Thanks for all your inputs and help on getting my problem resolved !

As you know this is my setup (I just posted it for people who didnt know) SUB:(1) 18'' Fi.BTL (Fully Loaded) D2,cooling,hixm coil,induct heat ring,daily 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 (1):PAC 200amp Battery Isolator (3):300amp Iraggi HO Alternators 2 Kinetik HC 2400 Batts. Big 3 done (beefing up my electrical system) etc. Al…

Do you think 2 loaded BTL's with daily option will work with 4 SAZ-3000D's in a SPL only setup (burp). This will be a 16 volt system and box after sub and port displacement will be 8.75 cubic feet tuned to 50hz. If not what subs.

So there is someone selling a blown 15" icon and i was thinking of picking it up. I was wondering if I could recone it with Q coils and put it in a 3 cu fu. @ 32 Hz? Would this work or am i just thinking to crazy? also how much would a 15" Q recone cost to 94803? thanks

I have a old kicker SX 1250.1 amp. its rated 1250+ at 1 ohmn. my question is what would be better for the sub and amp? 1 or 2 ohmn's? the 1 would be getting more watts so it would be louder but if i ever switch amps will that effect the 1 ohmn? the sub would be a 12in Fi BTl N1 sub, its rated at 2000rms, idk which to get 1 or 2?

Allright i got my btl in and the dustcap got hot really fast and i mean hot hot i have 8ga wire running to the speaker and 1/0 ga ran to my optima back to my kinetik 2400 and ran it full tilt and this happend its a duel 1 fully loaded and it is in series to make it a 2 ohm load the amp is a Rockford Fosgate t2500.1bd everything seems to be fine i mean i have not "Broken" it in yet..need some help does it matter which terminal i use to run series?

my glue is coming loose from the surround to the basket what can i use to reglue

How well will this enclosure work for an Fi Q 10" sub. B

i have a home audio 15" powered sub that needs replaced was wondering if could drop a IB3 in it if it would be alright? Thanks Jesse

Ok I've been trying to get my subs reconed for about three weeks now, I already know that they wont be covered under warranty because I overpowered them, but i have the money to get them fixed so if someone that works for fi could send me some info to get me on the right track, i would greatly appreciate it. Subs are:( 2) FI Q 15's D1 w/ BP power. THanks

Please tell me this is a warranty issue...? It happened last night noticed one sub quit, kind of looks like the wire was to short, there are no rips in the speaker just a broke wire? this is a Q 10.

hello I would like a design for a single with dimensions of 17H, 40W , & 18D Mmaybe alll the WAY to 22 but sub will be to close to trunk wall ... on you tube thers a design double port the guy has It on a civic very nice.oh and tuned to 33 to 35

a question for the man shawn fleming and any body else that know about spl boxes.for spl only,which box would be louder for a btl-18 with 5000 watts.a 6.2cf box with 98 inches of port,tuned to 64 hz. 7 cf box with 114 inches of port at 64 hz or a 8.5 cf box with 138 inches of port tuned at 64 hz also.for spl burps only.this setup is going in a astro van,4-btl's 18's.trying to find best box config.with port on driver side.all thoughts are welcome and valued.thanks BP.

I have a 12" bl and and I recently built a new box for it. I noticed some what of a clicking sound coming from the sub. At first I just thought it was something rattling in the back of my car but today I went to check it out and noticed it was coming from the sub. It only seems to do it on the low notes and it doesn't do it every time either. I can't seem to figure out what or why it is making that sound.

Do you guys offer a recone kit from Fi that will fit the RE SX motor? If so, could you PM me a price please? Also, would you be willing to sell the recone + motor for a Q? Let me know!

i was browsing caraudio.com and i saw a btl "UFO" for sale and it looks like it has a spacer between the basket and motor? mine does not have one of those, was that constructed for the himXcoil??? here is the link http://www.caraudio.com/forums/subwoofer-classifieds/510334-215in-fi-btls-1-15in-ia-dp.html alo here is another http://www.caraudio.com/forums/subwoofer-classifieds/510333-sale-15-fi-btl-excellent-condition.html
