Fi Technical

So im about to build my first ported box and i need a little help. My 15" bl will be getting 2000 watts and has cooling and flatwind options. This will be going into a 96 infiniti i30 (same as maxima) My goal is to have the best LSQ setup as possible leaning more towards spl. I think i want to tune ~35. If the box is 4 cubes with the tuning at 35, is a port size of 4W x 13h x 21.8L correct? Is that enough port area? And is that a good tuning for my goal? Also if i use 2 circular ports that are 4" in diameter and 10.5 inches long would that be enough port area and the right tuning? Thanks a lot -Rick

Im getting a Fi SSD 15". I need to know what options to get and what i should get for an amp. Its GOING TO BE A DAILY SUB THAT WILL BEAT TO ITS MAX EVERY DAY. I want to go with the hifonics brand amp and wonder which is right. I myself think it'll take 1,500 rms no prob. These are the amps im considering... I want to get a 4.0 cu ft box tuned to 32 hz HIFONICS TXI1508D ---------1,500 rms HIFONICS-BXI1608D ---------1,600 rms HIFONICS BXI1208D----------1,200 rms All are 1ohm stable Im going with hifonics cause they are affordable but open to others. i only have like 400 for an amp.

SO my buddy just picked up 5 diamond cm310d4's but two of them need to be reconed so i got a couple of q's 1. can you guys make up the recones an ship them out or would they have to be done inhouse? 2. what does he need to give you as far as messurements? (if recone is shiped) 3.would he also have to order new baskets since his are a stamped 8 spoke? 4.what would the price be on each one? (would it be cheaper to do all 5 at once) thanks for your help

need recones desperately I can best be reached by email [email protected] or at night time ( eastern time GMT -5hrs) im on MSN till about 12-2am same email addy please respond as my email has not been replied to... I know u get lots... or just pm me a phone number I can call

I own a BL and am buying an SP4. will this box design work perfectly for the SP4 and well enough for the BL? did i screw up on anything? at the bottom of my port i have bracing crossing it, will this be an issue? should the port be fully open down to the bottom of the box? i could not find any great info on port area for the SP4 so im sitting a bit over the 16 multiplier right now. i was thinking of adding a bit of that fluff to the box to make the sub feel it was in an enclosure closer to 8 cubic; is this a good idea? im going for SQ at high volume, or at least as much SQ as the SP4 can give me. what should i change, all opinions welcome. thank you. http://imgur.…

Hello, I have a kicker zx.750 and a single kicker 12 inch solo-baric L7 woofer. I tried a ported enclosure and now it is in a sealed enclosure, but I just am not getting the bass I am looking for. I have been looking into a Q series woofer and was wondering what size people would recommend and how big of an enclosure for the wattage put out by the zx.750. I currently have a 1992 lexus es300 (4 door sedan) but may possibly be buying a 1998 ford expedition. Could somebody give me some advice about what to do?

how much power could one safely put into a fully loaded Fi q 18? i got my sp4 fixed and will be testing some boxes but if i dont get the sounds i want i am going to sell it and buy another sub. the Q seems a logical choice as i want more frequencies but also want to keep the volume. i am undecided on single or dual or sealed vs ported. my thought was that if i replace the SP4 i would get 2 q's and thus have greater cone area with more control and higher bass frequency range. in my mind that would mean i could get more volume out of them than the sp4. the power handling would be close to the same

I am thinking about getting a pair of fi q 12's I am going to be running them ported in a daily trunk setup on a Saz-3500v2. I am getting the cooling option for sure but for I am not sure if I should get the extra spider & the internal lead options, I am thinking no on these options but I would like some opinions before I drop my cash on these subs.

Hey, I've been looking at Fi car audio for a while to help fix my BMW's horrible lack of bass. I was originally looking at the 12" Q but after reading around I decided that the BL would better suit my needs, I now am at this problem I know my trunk can fit the optimum box dimensions for the 10" and 12" but I dont really want to sacrifice all that space but then I want it to also to be hitting pretty hard. Also whats a good amp recommendation for the best price/performance

just finished reconing my 18" BTL a few days ago.. been breaking it in at low volume.. after i thought it was broken in, i turned it up slowly and as i started getting to about 1/4-3/8s level of where i would normally play at my sub makes some what of a clicking noise to the sound of the bass, kinda sounds like plastic on plastic nocking/rattling.. any ideas from any one here as to what it could be ? havent pulled the sub out of the box yet to check anything, dont want to if i dont have to..

Can someone tell me why about 1/4 of the spider would be torn and a lil crispy and the rest be fine? the coil looks fine too btw...powered by a KX1200.1 in a 2.6 internal sealed enclosure...it smells AND feels as if it were on fire...the gains were fine and everything, i wasnt even playing full tilt when all the sudden...silence, no pop or any sound, just no bass and the smell

Has anyone used the IB3 series subwoofers, specifically the 18" in a home audio open baffle application? If so, what were the results and how much eq was needed, if any? If ordered new, does anyone recommend any modifications during manufacturing that would improve OB performance? Thank you!

hey guys i was looking for someone to help me try to design a dual reflex bandpass for my 2 15's, idk if this is something that each sub would beed its own box, if so thats fine but i would like both of them to be in the same one. if this is gonig to be a bad idea just tell me and i can make a slot ported box for them. i would just going to try something new. hoping to have them tuned to about 32-34hz i will be running them off a BC5500d. i have 4 yello caps, with another under the hood. i am using 4 RF power series, 2 6.5's in the front and 2 6x9's in the back running off a rf T8004. big 3 done with fat mat everywhere. planning on using MDF with a lot of fiberglass on th…

Hi, in the future, I am going to order a btl n2 12 and build the box up to reccomendations, and I just want to know what am I to expect from this subwoofer spl, sq and just over all loudness wise. This will be my first system, I just want to know should I be set with just 1 btl 12?

can anyone tell me if i can fit 2 BL 15s in my trunk the biggest dimensions i can fit are 17" height, 27" depth, 37" width, i dont think i can do a trunk facing enclosure but i think i might be able to wall off at the back seats. Running in a 2001 Oldsmobile Alero sedan Cresendo bc2000d at .5 ohm

I have a blown Pioneer Premier w3002 D2 and I wanted to know , could I get a recone for this sub with Fi parts. Its 1000rms.

I just recently bought 2 FI BL 12's fully loaded with 4 inch voice coils. I have 2 questions for the forum if you guys can please help with me. First i am running a Rockford Fosgate 2500-1bdcp on the and since the subs are dual 1 ohm is this enough power for them? Second, the enclosure i had built for them is 4.23 cubic feet after everything and tuned to 33 hz. Will they sound good in this enclosure or should i have made it bigger? The amp puts out 3,526 watts total. Thanks in advance.

New to the audio scene and was posed with this question.. Lets say I am trying to squeeze a box into my car, and the trunk fully stripped, can only accept a box that is a max height of 15.5". Would it be possible to fit a 15" Fi SSD in a box that was reduced to 15.5 inches tall? Wouldn't that affect the integrity of the box, being that thin on the top and bottom, or would that even work period? More in depth: Id have to bet that there would be a lot of sanding/sawing involved. I am in a predicament, as my sub faces up in my 1st gen mazda 6 sedan. The actual trunkspace has PLENTY of width, and depth, but the entrance inlet from trunk, or seats is not vary tall. As stated…

My 12 " Qs sounded bad since i bought them a few weeks ago (used) so today i figured i would build a new ported box for just 1 instead of having both in a sealed box. This is what i found when i took the woofer out. Looks like the motor wants off the basket pretty bad!!!!!

need dimensions on a box for a 15 fi sp4. website says 3,5 cu ft but other people are saying go 4 cu ft. really would appricate it

Bought a new Fi Q 12 and i was wondering if you guys could help me out with the enclosure, i have a hatchback its a golf with Cdt es-520 with upstage up front and cl-61a in the rear powered by a Directed 1100d5 and strapped to 600d for 1200watts @ 2ohm for the sub. i listen to wide range of music but mostly reggae, hip-hop, r&b, rap, pop, and some classics. My goal is sound quality but i would also like it to be loud at the same time without sacrificing sound quality and with that said would a sealed or ported enclosure best suit my hatchback. Thanks guys!!!

alright for about 2 months now i have been breakin in my 15 inch bls...... so can i feed them more power now?? or should i stay the same?

I bought 2 used UFO motors and they are different motors completely. The one has "cuts" in the side around the slug in the black part and the other is just smooth.plus they seem to be different sizes? I already ordered the single slug recones. Are they OK to use together
