Fi Technical

Ok i have two d1 q 15 w/bp power and when I first recieved the subs, they hit extremely hard but after a couple of weeks and a local comp, the subs just dont perform like they used to. when they hit the lows now the bass kind of fades away and sounds like a fart and they dont even put out the pressure like they used to either. I've checked the box first to make sure there were no leaks and everything is fine. I think the spiders have gotten weak cause they just dont "thunder" anymore. Time for recones right?

Hey everybody, as you can see im a newbie lol but my question is im plan on getting a 15" Fi Bl w/ p chamber option and its going to be running off a Rockford Fosgate P1000 1bd (1000+rms) and i was wondering if I needed a new car battery or should i just hook up a cap to the amp

Ok well i built a box for an 18" Fi BL the specs are 42" wide, 22" high, and 22" deep. The port is 5 inches wide and 15.5 inches long. tuning it in the upper 31hz range. The box was like 8.3 cu ft. before woofer displacement. is that too big for a 18" BL with flatwind coil? Because the box doesn't sound good at all. and the woofer gets pretty warm on zx1000.1. I feel like its too big but i could be wrong.

I haven't purchased the Q yet but here is the box. Will the bracing get in the way or will I be good? I'll get measurements tomorrow of how far from the hole the bracing is and how many inches in between the two peices if that would help. Appreciate it!

Hey everybody i have a quick question, im thinking about buying a 15" Bl but i heard that if I just listen to rap and hip hop that the 15"Q would be the best is this true and also its gonna be running of a RF P1000 1bd do i need the bp power if i get the Q

hey guys, i ordered 3 Q 18'' subs which i intened to use in a ported application but for some reason not sure how the high QTS option was selected..and in the options it says this is for only sealed applications..so i sent a email thinking i would be ok since it says there is a 30 day wait time but i just got a email saying my subs have shipped so im not sure if they got my email in time and made the change or not, so my question is how bad will it sound if i still throw them in a ported box even though they say the option is only for sealed applications?

I've never done a recone before, and I was wondering if there's instructions on exactly what needs to be done. And how to use the adheisive kit that comes from the website. Thanks for any help.

After hearing a BTL for the first time yesterday i have decided that i want one, really bad. I will only be pushing 2000 watts to each sub in a daily setup (no comps). Is there any point in getting the high XMax coil, does this loosen up the suspension for better SQ. the BTL that I saw was only getting 1500 watts and didnt seem to flex much so im not sure if the high xmax coil would really do anything. Thanks, Keith

i recenly got a 12inch bl and i just got it installed today and it is clipping i have an Alpine MRP-m1000, And the faceplate is an Pioneer - Model: DEH-2200UB i have the gain turned down but it isnt hardly hitting at all it is in a 2000 dodge intrepid and when i do turn it up you cant hear the clipping cant hear the clipping inside but once you open the trunk you can hear it clear as day here are the options for the sub Ohm: dual 1Hyper_Pole: noCooling: yes +$30Flatwind: yes +$15Daily_or_SPL: DailyUniversal: noDustcap: white

I've been E-mailing Scott from Fi Audio back and forth but it usually takes a while for response and i realize hes bussy at the dB Drag World Finals. I desperately need these specifications for my Fi X 12s. LE in Mega Hertz- Z in Ohms- PE in watts- Ive been trying to get this info for weeks now so that i can finally build my box. I would really appreciate it if someone could help. Thanks, Ben

Im looking for some peoples opinions on what to run to my bl 12 at 2 ohms.? comments are very welcomed

Hey guys. Got a question concerning how much power to give a BTL. My previous system was a loaded 12" BL @ 1ohm load, and pushed by a 1500D amplifier with gains at about 7/10 and 4V headunit @ 22/35. I figure it was about 1200RMS? Now, I see all these people with BTL's saying they push them with 3500RMS+. I just don't see how that's going to be possible.. I'm asking because I figured I could get away with running a 2500D amp for a single loaded 12" Fi BTL . Should I really be looking at more powerful amps?

I have an older RE HC 15 with the 4 spoke basket dual 2 ohm version and need a re cone kit for it, it final blew about 2 weeks ago. I have been trying to to contact Fi via email with no response. Was wondering if anyone knew which recone kit on their web site is the correct one and will fit on the HC motor and wanted to get it upgrade if possible and add a need basket as well? Can anyone help me ?

i just planned to put my 18 btl in a 6th order bandpass (60 hz / 30 hz tuning) and i already got the wood sawed too. ive never tried a bp yet so i thought it would be nice to give it a chance. what do you think? is it better to put the btl in a big ported box or go with the 6 th order. i currently have a 5 cft ported box @ 30 hz but i want to increase efficiency and loudness of the box. amp is a bxi 2610.

FI please remember to add the shipping address to your shipping labels! not just the city and state grrrr... Was looking forward to my Q, guess I get to wait a bit longer until UPS figures out my address. Hopefully you guys are not out on Vacation... I need to vent

Alright im not realy sure about this so ill ask it here. I ordered 2 18in D2 Single stack recones with highxmax coils but there not flatwound. Is my order wrong? im under the assumption that these should be flatwound for better power handling and cooling.

ok hello everyone, i dont know if this is the right topic for this forum but im starting to pull my hair out looking for a good solution.... i have a 1990 toyota celica gt does anybody know of a good high output alternator for this car? i would be happy with a 150 amp or higher my budject is 350 ive looked at ohio,mechaman,irragi,denso,powermaster and couldnt find anything those are the brands most people reccomend. i dont want to buy a brand i have no knowledge of and be a piece of crap. powerbastard has import universal one but ive heard bad reviews any body have a solid solution or idea? greatly appreciated..

I know that posted t/s paremeters on ficaraudio.com are for the stock BTL with no options. would it be possible to get the t/s params for the common fully loaded BTL built for daily music? Just curious to see how it changes, and I know you guys will always say stick to recommended box design, but it would still help me to have the t/s params.

Will a 15" Fi Q with BP power be ok on a AQ2200D amp at 2 ohms (1300 watts) or will that be to much power?

I'm sure it's probably not a big deal but my my dad had accidentally barley scratched the surface of the surround of my sub and decided to put a bead of epoxy to cover it and I was kinda upset .. And also while removing my sub from the box my right hand had slipped and accidentally hit the dust cap .. Nothing was damaged because of the hard cap but will these effect my sub and should I worry about it or is it not a relaly big deal?

I need a box design for 2 12in fi qs with max diminsions of 30W x 17H x any depth. Preferably with the port in the middle. Thanks.

I need some help with the dimensions of my slot port before I go ahead and make a disaster. I have a 15" SSD in a 3.8 cuft box. I'd like to tune it to 33Hz as per Fi's recommendation Using one of those online calculators I got the following dimensions 3"H x 6"W x 5.22 L Does that look right? How would that be affected if I wanted to make 2 ports? Any help would be appreciated

Title says it all. I can build a enclosure with about 11 cu ft (internal volume, displacement of the subs has been removed). I read on a forum a while ago that you get the best SQ if you go with a big vented enclosure. I want to hit the lows but not to loose the highs completely. I listen to almost everything that's called music. That means from Queen to ATB to Bob Marley. My goal is SQ. The car is a Toyota Celica GT, this one: I will be using a Hifonics BXi 2610D amplifier pushing 2600W rms on to two Fi Q 18" subs. The optimal vented enclosure as I have read is from 6-10 cu ft for one, meaning 12-20 cu.ft. for two subs. Or 4-8 cu.ft. for a sealed enclosure, 8-16 cu.f…

i. I have an old Fi Q that I need to get reconed. When I cut up the soft parts and cleaned up the basket I. Saw it had "Q D2". I figured that would give away the time period in which it was made. I was wondering the power handling of the magnet, as I was thinking of reconing it with a BL recone kit. Could I do that with a Q magnet? I have a mmatts d300hc reconing it to a dual 1 would be my plan. Could the BL recone work with this magnet?

I have an oppertunity to pick up a pair of TC9 Motors for cheap. Can these be made into subs by Fi? Looking for 10" subs. As well, what is the power rating on these motors?
