Fi Technical

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

I'm putting a Q10 in a sealed box and am looking for a good size for SQ. The website recommends .2 to .6 cu ft. I should have 1000 watts @2Ohms available. Would a larger or smaller box lend itself to better SQ. Thanks.

Im tryna purchase 2 Fi BL 15's and i have a power acoustik BAMF40001/D...Im wondering how I should wire the voice coils and would it be better to get a dual1 or dual2???...This is for daily use also

Ok so i have a FI BL 15 Fully loaded powered by a Sundown SAZ-1500d. Ok so anyway when i play some music loud i hear some weird sound like the sub it bottoming out but i know its not becuase its not moving enough to bottom out.

Hey guys! as of a few hours ago, i ordered a 15" BL and a Sundown SAZ-1000d amp! I was just wondering how you guys think this will sound! and suggestions on my box. I want to make it ported offcourse

Could I use a Brahma's 12 spoke basket on my BL, with an Fi recone kit to upgrade my 10" to a 12" ?

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.

2004 Monte Carlo a pair of 18" fully loaded BTL's a pair of Power Acoustik A3000D amps one lonely termlab 500 pounds of wall... 153.6 @42 hz windshield 152.5 @38 hz MECA reality stand 151.8 @30 hz winshield ...and just for Meade... 150.6 @27 hz all in all these subs are very impressive and tough. the monte carlo lacked a lot of the needed airspace to make this setup do the 155 i was projecting but a little added wattage will fix that issue (BTL's like power and dont be afraid to give it to them). innitially there was some metering issues getting the car to go over a 150 which is the main topic of my post. 40…

I need help on how to fix my torn surround. Can I get a replacement from Fi and repair it myself or do I have to send it in? Is there a proven way to fix a tear in a foam surround other than shoe goo? Also, can you determine the options a sub has without tearing the speaker apart? Thanx guys.

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.

Guys, I know the BTL enclosure recommendation for the 15" BTL is 3-5 cubes net, however I also know that required volume is also dependent on power supplied. I was wanting to know if there would be any problems with running (3) 15" BTL's in a 8 cube net shared chamber enclosure? I should have roughly 3500 watts on tap for each sub, but I will not submit them to that much power, I was just wondering what I could get away with in terms of enclosure size? This is a daily beater.

Is 324sq in per sub too large for a striclty SPL enclsure using 4 Fi BTL 18's in a 32cu ft. box

I was wondering if 11.25 net tuned to 31hz and 166.25 square inches of port is too much for 4 fully loaded 12 inch BL subs running off of 6,000 watts of power?

im going to be getting a 15 Q soon going to be powered by a sundown 1200rms at 1 ohm and i need a box could someone suggest some box sizes and tunning i want it to be loud hit them lows hard

Hey guys. Can you recone a RE SX 15 to a 15" BTL? Let me know!

Does anyone have or know where to find a wiring diagram that shows how to wire a single 1 ohm sub to 2 ohms?

would i be fine if i just did the big 3 upgrade with 0 gauge wire. I have a 12bl fully loaded and a sundown sae 1200d.

Hey guys, first post! Haha. Well, I recently just received my 15" BTL in the mail. I was looking and it and noticed that there were no screw holes for mounting the sub to your box. So how do you mount it? Another question I had was, is there a special way that I should be breakin in the sub? I didn't know if there was a good way to do it. Thanks guys and appreciate all the feedback.

In another fourm Im being told I need to change my tuning frequency from 32hz to around 60hz. Im running a FI q 12 d2 with a Crossfire VR 1000d. It would be for outlaw spl only not daily. FI doesnt recommend going outside of there suggestions, could any harm be done to my sub by tuning it this high ? Would there be any gains ?

i want to get a 15" BTL and put it in a 1999 dodge stratus. i cant decide if i want a ported box with the BTL firing at a 45 degree angle towards the trunk and have the port firing towards the seats (i currently leave my back seat down, it is MUCH louder). OR go with a sealed box with the BTL firing towards the seats with my back seat down. i was thinking a Hifonics Brutus 2406 for it, which is 2,400 watts RMS at 1 ohm. i would get it fully loaded. PLEASE MAKE ALL THE RECOMMENDATIONS YOU WISH! another thing is the new BTL's, there is no triple stack magnet!?!?!?!?!?!? it is just a single magnet, why would they to that???

i need a box design for 2 18" btls. i have enough trunk space but where the port and subs would fire kinda confuse me. the dimesions of my trunk are 27x42x25. would that be enough to run 2 btls with port area? can you even run the btls sealed. i never see anyone talk about sealing them. please help cause i am tryna purchase these subs and keep it movin. hallelujah holla back.

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

For my Alero trunk I'm eventually going to buy a BTL 18 D2 with daily/all options. This is the cheapest & loudest daily setup I can think of and I've drawn up a shizload of boxes. I want lots of bass but don't want to shell out for a huge amp, alt, and batts. Power will be maximum 2000-2200 watts @ 1ohm unless I can borrow a huge amp for burps if having 1 fully charged battery will git-r-done. I will buy 1 battery and upgrade the alt if I have to but nothing crazy. RE Enclosure Calculator 1" MDF with 1" double baffle and no other bracing besides rabbit joints which I still am not sure if to use .25". 37 width x 28.72 depth (29.72 with baffle) x 20.5 height Displacemen…

Hi everyone. im just stoppin by cause i was wondering how much it would cost to get a recone on a SSD sub. thanks

I'm too lazy to A. Look down this page a bit to see the other 8 questions asking the EXACT SAME THING. & B. Use the search function. & C. Go read the stickys at the top of the page that list recommended enclosures for all of Fi's subs. ...so I figured I'd pollute the board some more with my "problem" that really isn't a problem, and doesn't need anymore discussion. Thank you.
