Fi Technical

Having 3000 watts on tap, which can be made louder in a large ported box? 4 SSD18's or 2 of the more efficient BL/BTL's? TIA, Carl.

I was wondering which setup would fit better. i currently have a kicker 750.1 and i was planning on gettting a fully loaded 12" duel one ohm sub and running it at 2 ohm. I was wondering if that amp would be enough. If not then I plan on getting a fully loaded BTL 12" duel one ohm sub and running it with a Lanzar2000D. Thats supposed to put our 2000watts @ 0.5 ohms CEA rated. Which setup would work out better?

I recently found out my Tinsel Leads were blown and i'm not sure how to fix it... Is this something i could fix on my own? Or will i need to send it in? If so how much will it cost? and where do i send it in too?

Hey I ordered a SSD 15 with both BP Power and Flatwound coils that I am going to be pushing 1000 watts through with a Rockford Fosgate Prime 1000-1d amp at 2 ohms. I was wondering if the box I have planned out with the RE calculator would work with my setup. If not, some advice would be appreciated.

Im getting a fi btl n3 18 and haven't been able to find any dimensions to build a box. Can someone please give me dimensions to build a box and I want to tune the box to 32hz and pictures would be great too

So i am using my 15" Q for a home theater sub, 12cuft tuned to ~12hz or so. It is a monster on only 1000 watts. Through reading allot on subs and linear tech im wondering how the Q's coil is setup, underhung/overhung, any linear tech, shorting ring, and if there is anything special about it? Im more or less wanting to compare what i am listening to and what its tech is compared to what some people are using. I have to say though that the Q in my enclosure is a pretty amazing experience. just need to get maybe another 500 watts to it and some way of keeping my house's voltage stable. thanks!

Ok guys heres the situation. I ordered a BL 15 with cooling and flat wind dual 2 ohm. I'm building a box myself and having trouble on what to do with the port. The box is planned at 3.76 ft^3 with the woofer displacement added in. Its recommended to have 12-16 sq in of port per cube so i need anywhere from 45-60 sq in of port. I want to just maybe slap a 3x6 aero port or maybe a 4x6 aero port. The 3x6 is 42 sq in and the 4x6 is 75. Both not in the range i need. Also looked on amazon and found precision ports 3 in and a 4 in round. Doesn't say the length on them tho . Reviews say there adjustable somehow. Help would be appreciated. Also wanted some recommendations on ampl…

I purchased a Fi Bl 15 Waiting on it in The mail (awaiting Fulfillment) and i am puting it in a 04 honda accord coupe i would like anywher from 3 to 4 cubic feet but being able to put in my trunk restricts the height it needs to be no more than 17 inches high can anyone help me with dimensions and or advice on how to come up with a precise enclosure build for my sub i would like to be tuned anywhere 30 to 35 htz it would be much appreciated

I need your help guys..... 1. Sealed or ported? 2. Does any one have a pre-fab box that works well? 3. Does anyone have box specs that I could duplicate?

Hi, I have had my BTL 12 for several weeks now. Its fully loaded and only receiving around 1000 watts rms (PDX 1.1000). The enclosure is 3 cubes after displacement at 34 hz. On certain notes, i hear a popping noise. The notes are almost always higher notes. The spiders and leads look fine, but i dont have much experience with them. Is it possible that i am reaching the mechanical limits of the sub in this box at less than half power? Amp is not clipping to my knowledge. Voltage is stable when the noise sounds (less than half gain, no bass boost). Oh, and the popping is only heard at half volume plus. The sound sounds like its coming from under the dust cap. Any i…

I was wondering is doesnt have a size recommended for the 15 ssd in a sealed box? Is there a reaosn for this? would they sound good in a sealed box? If anyone is running them in a sealed box how many cubic feet do u have them in? I cant run them in a ported box because the box would be to big to fit in my civic, any help would be appreciated, thanks

I'm looking at buying this used fi btl n2 and i'd love to know the specs if anybody has them or has a link to them,

I have a excursion w/2 -18 Q's and want to know if i can tune them to 30hz instead of 28hz? and should i have the port and subs firing to the rear or facing up? all my boxes always had the port and sub on the same side.I would face them to the rear. I would face my box up and the bass cuts in half. Will this do same if i face the subs up and the port to the rear? I want to get the most that i can get out of subs and box. Any input....

Hey guys I'm looking for blue prints for either a single or dual 15 inch ssd ported box with optimum area space. I'm not new to stereos or box building, I'm just way to lazy to design my own box. So I was wondering if there are any blue print boxes laying around like element designs puts out on there site. Thanks in advance and hopefully you guys have some so I can get to building.

I recently bought a 15' Bl and had a enclosure in mind. The enclosures dimensions would fit inside my car, so I went ahead and bought the 15' Bl with the cooling option. It arrived a few days ago and I was super siked. Then I realized how would I get this box into my 99' Grand Am GT. The box will not fit. (This one http://www.bestbuy.com/site/olspage.jsp?sk...=1218009774927). Now I'm in a pickle. I have found another box that is ported,that i think will fit in my car. It is on the small side as far as cubic feet wise though. link to it --->http://www.bestbuy.com/site/olspage.jsp?skuId=9026797&st=15+in&lp=4&type=product&cp=1&id=1218009790168 Will th…

hey guys, if i tuned a box to 26.5 hz would it hurt the sub? ik fi recommends 28 but i like it a little lower than it is now. so im gonna build a new box, and tune it to 26.5 if u think it would b ok. ne help would b great. thanx.

Is it that hard? How long would it usually take?

i currently have a 1997 mercury mountaineer with 2 q18's. i plan on walling it off behind the second seat with 4 q 18's. heres the problem i run into...the depth from top to bottom of the center of the back is 37.5-38 inches tall. but at the very back where the hatch shuts it drops to about 30 or less inches roughly. how would i go about building a wall with the subs on the same plane and port as well. i wanted to do the port in the middle with a pair of 18's on each side. but how would i get my box in. i want to avoid the pacman style boxes if at all possible. please help thanks. i know there are others out there with their explorers which is the same thing running 4 18'…

Hello everyone, Im looking for some input on new woofers. Looking to do two 12's in 6.5 cubes, ported to 29 hrz.(havnt designed yet) I am stuck between FI Q's and BL's I understand that its not entirely fair to compare specs of subs as there are many variables involved, but how does the BL's motor compare to the Q's? The Q having 28mm of Xmax and the BL having 19mm xmax. Is the BL's motor just much more powerfull? What are the real world diffrences and which one is better for my application? Amp is: 4,000 watts rms(1ohm). they will be wired down to one ohm

Hello all. I'm getting ready to purchase a Fi Q 12 and a Candence TXA-1000d amp and I was wondering what the optimum enclosure would be for my application. I drive a 97 2dr Exploder, and listen to rock/metal.......lotso heavy stuff. I want the sub to sound as clear as possible when hitting the bass lines and bass drum and still have a nice thump too. So, if anyone has any ideas for specs for me that would be frickin' fantastic! Thanks, Mo

Finished the recone on a fully loaded BTL 15 today and this thing sounds even better than what I wouldve ever guess... I have one question though... I brought the sub to a friend who owns a shop to get the recone and after playin it a bit... Pulled up to a friends house and noticed the dust cap fell off, so I bought some more epoxy 5 min loctite and put it back on no problems. After expecting my little glue job the dust is maybe 1/16 of a inch off from where it used to be. Will this hinder the subs performance at all? Its sounds fine to me, still loud as chit...(My wife said it sounds like a machine guns going off in the trunk.LOL) this is only a temp system... Next syste…

ok here is my question can i run 2 amps (mtx tc4001) on a Fi q 12? the amps are rms 600x1 at 2 ohms. i know that the FI's are dual 2 ohm. right now i dont have the cash to buy the amp i want(sundown). the other mtx amp should be here soon but until then can i only run one VC? is that safe? any answers would be nice? my friend has one of the FI Q 12 in his 06 Z71 and man it sounds great... i want that sound

Me and my friend are about to hook his car up with some Fi subs. We are unsure of what really seperates ported from sealed and how power makes a big difference. Right now we are lookin at 3 Q 10's sealed, 2 Q 12's ported, or a 12" BTL ported. Q's will get 1k watts each, the BTL 3k to 4k watts. We listen to everything from heavy metal to rap. What we are lookin for is a rough idea of how each of these setups will differ in every aspect. I know it sounds like a lot and we are grateful for it. He says he may wanna compete in something with it later, so that is something we need to keep in mind. Any help or suggestions would be great.

Well im running my 15 q ported right now and ilike the way it sounds but i was wondering how many of u are running them in a sealed box? I know the ported would most likely get deeper than the sealed but i was wondering hwo much of a difference it would be sealed and what other peoples opinions on the q sealed are. I do listen to alot of rap thats why i went with ported. Was wondering everyones opinions on the ported vs. sealed. thanks

What are the wiring options for the D1's? I can't find any charts indicating the wiring options for a D1 sub.
