Fi Technical

Okay, so I guess the way the cooling is designed or the motor or something is causing loud air noise around the motor that is very audiable when the thing is invert mounted. There should be some kinda warning about this, as my whole install is based around the idea of an inverted driver. fml.

2 12" Fi Q subs in sealed separate 1.2 cu ft chambers powered by an AudioQue AQ2200 amp. On the amp I've got to turn the gain and bass boost all the way up and on the head unit the subwoofer and bass levels to the max just to hear the subs, and barely at that. Something is wrong here, and I need some help figuring out what it is. I've double checked, redone, and double checked all the wiring, and it is correct. The subs are 1 ohm DVC, and measured at the amp, is exactly a 1 ohm load. The polarity is not reversed anywhere. Tested the DC power at both the battery and the amp to see they are the same. Tested for a ground loop to find none. I'm at a loss as to what to look …

So im about to order two fully loaded BTL 15's and Im trying to decide whats the best amps or amp to push them to the max. Right now im looking at 2 kicker 2500 or two rockford 2500. Any suggestions?

I have 1 15 BTL Fully loaded, i was playing it today and it started smoking then went out. I have it on a Orion Hcca 5000, the gain was not up it was below half way, i wasn't playing it for a long time, i don't know what could be the problem. If you have any ideas what the problem could be, or what I could do please let me know, Thank You.

I ordered a mild Built FI audio BL 15 last month. It showed up last night. Unfortunately it has a big chip out of the top magnet. I want to run this inverted so now this is throwing that idea all off. The Sub was packaged very well from them and the box sustained no damage anywhere during shipping. Must have slipped past FI Audio on the way out the door. I know it probably isn't going to hurt anything but for looks sake it's really bugging me. Its there a Rubber boot or something that I could cover the two magnets with so it doesn't stand out so much? I see some other sub brands have these boot's or covers. Here's a pic. It's kind of crappy but the Magnet was jack…

whenever i plug in or out my mp3 player into the stereo my Fi Car Audio SSD 12 makes a pop sound .. so when i was playing my music i gradually made the volume louder then all of a sudden the sub will pop and start this loud humming noise.. i dont think i blew it because i played it again and it sounded fine until the pop and humming sound came again

OK, i am doing a system for a friend in a 1996 lincoln town car, the equipment i am getting is 2- 18" SSD's and will be powered off a Rockford Fosgate t1500-1bd . The problem is there are hydraulics in the car so i have very limited trunk space to work with. the measurements i have taken leave me with a max of 39" wide x 24.5"length x 14.5" tall . i think this comes out to be about 6.6 cu.ft. BEFORE any displacements . I know that this is WAY UNDER THE RECOMMENDATION, but i do not have any more room to spare. it will never be metered or compete it is just for show which is why he wants the 18's but even though it's, not going to compete it still has to be LOUD. I was…

so i bought my btl 12 in late march. and i just got the money for my new amp. a alpine m2000. but the amp kept cutting out. and i tested the voice coils on the sub and i've got a bad one. it seems to me that it was never right. and i was wondering what i should do about it. i'll call FI in the morning but do you guys have any suggestions?

hey guys I'm looking to get to BL12 but wanna hit 150db or more. Any advice on enclosures AND what sort of amp or power do i need to accomplish my goal? my purpose is all out sol here to get a high score with 1 single 12" sub!

whats up! im running a D1 Fi Q12 with a DSC2000.1D @1000watts...but its in a pos pre fab box. I want to step up and build a box with these specs 2.5cf @ 32Hz how do the dimensions look, will this get me to 32Hz?

I have the ability to do a drop in head to head test w/ TermLab results between a Havoc and a Q 15 ported tomorrow. Anyone interested? And any other test you guys want? I have a TermLab, a Havoc 15, and a Q 15 so all is good to compare if there is interest!

What would be louder 2 12 btls or 4 jl w6 on 4 k btl will be tuned 2 33hz w6 will be sealed.

1 12" Q with BP Power on a Rockford Fosgate 1500w amp wired at 1 ohm (so the sub will see 1500w) or 2 10" SSDs with flatwind coils and a US Amps MD 2D (so the subs will see around 750-900w a piece)... Both would be sealed setups. Thanks for the help

ok so ive had my sub for less than a month and today i heard strange pop. so i went to take a look and it just sound like a screw was loose. so i took the sub out and it wasn't that. Then i played the sub out of the box and when i turned the volume to about 30/62 it started making the same noise. it sounds like its coming from the center of the sub. so my question is what could it be.

What are they since there not posted on your website? Actually, none of the parameters for any of the BTL's are posted on your website?

how do i get the spider off the basket? ive been sitting here for 40 min with a razor and all ive managed to do is remove a 1/2" section and cut into the aluminum basket.

Hi everyone, first post here. I have an Fi Q 12, I ordered it fully loaded with the high QTS option with the intention to use it in a sealed enclosure. I currently have it in a 1cu ft box. Unfortunately the sub response really rolls off below 35-40hz, which is very disappointing. I have had much lower end subwoofers in sealed boxes that were actually much better on the low end frequencies. So my thoughts are to try it in a ported enclosure and see how it responds. Problem is I have High QTS. What will happen and how will the sub react to a ported enclosure? If anyone has any input on how else to solve my issue or any ideas about the enclosure let me know, it's greatly a…

since I've been frequenting this forum more, I have noticed there is a significant number of issues with the Q line. I'm guessing just coincidence? Or is there a ryme or reason?

The other nite we were changin the box my fi's are in and the drill slipped and went through the rubber on the subwoofer.. He said if we put rtv silicone on the inside and outside of the cut it would be ok but Im not sure any help would be good

So I own 2 18" BTLs. I have 2 memphis 4ks on each, and they are very loud. Because of the area I live and and personal preference, I don't choose to flexnuts very often (well once a day). Once a day I drive past my ex-fiance's house (who I left after finding out she was cheating on me). This is my once a day stress release- since she's always outside smoking and she tried to prevent me from getting subs-she hated bass- and now she gets to hear them all the time Well, I was listening to da blow by lil john, when I noticed my mirror going crazy. Then it fell off. Guess I'm going to have to go get some repair glue from walmart/advance auto tomarrow. After opening the bac…

Just Got my car finally! OMG! YES finally.... ffs Vauxhall (Opel) Corsa Sxi Twinport 3 Dr it is... now i have an Fi Q 15" which im going to go sealed and will be making a new enclosure in the workshop soon, thats sorted, going to get my self a sundown 1000 amp.. now i was just wondering about wiring products, http://www.knukonceptz.co.uk/productDetail...?prodID=KLM-AK0 http://www.knukonceptz.co.uk/productDetail...?prodID=KAR2-6M http://www.knukonceptz.co.uk/productDetail...rodID=KAR124BLS http://www.knukonceptz.co.uk/productDetail.cfm?prodID=ANL200 and some form of terminal cup for box i just want to know if this will/should cover everything to get my sub up and pumping …

I have a dual 1 ssd sub with the copper coil option in a 1.1 sealed box powered by an audioque 1200d. And im wanting more deeper bass and louder but trying to keep inline with my sq setup. Would a sealed enclouser with more power? Do I port the sub and keep the same power? If i would port the box what cubes would u guys recommend? The space want to put it is 15.25H x 12D x 31.5W these numbers dont included the thickness of the wood and the double baffle. I could put it in a different place if i cant get it to fit.. And What freq would u tune the port? Thanks for the help in advanced.

I am planning on building a 4ft^3 for my BL 15. I was just wandering what size my slot port should be (Length, height and depth) if i want it tuned to 33hertz?

I recently upgraded to 2 BTL 15s from a 2 Qs. In a nutshell im having the same problems that i was having with the Qs, Overexcursion. I am running a MTX TA81001 to each sub, only 1500 watts. The total volume of the box after displacements is 8.5 cubes, port is around 100sq inches and is tuned to 32hz. SSF is set at 30hz, HPF is set at 150hz, Bass boost is set at 0, and volt meter reads 38 volts which should make the amp put out 1500 watts. I went to my local shop (Pure Pressure Audio) where everyone who works there runs FI. They said i need 6 or more cubes for each speaker, and my box is causing them to move as much as they are. I built the box to FIs specs and it doesnt…

After first seeing the specs on the website, I noticed there are a few necessary specs not included. #1: I noticed the xmax, but nowhere did I see the xlim. #2: Recommended type of port(s)? (shape/size/depth) If I list the specs of my vehicle, maybe someone can get an idea and throw me some info. If any other info is needed, just ask. 1995 GMC Sierra LT ext cab 6.5ft bed. Rear seat bottom and back will be removed. .75" MDF enclosure with internal dimensions of 45"W x 30"H x 25"D. Subs will be up-firing. Should ports be front, rear, up or side firing? Where should the ports be located in terms of speaker location, between subs, at corners, etc? I will be aiming for…
