Fi Technical

I bought two bl off cl an want to make them fullyloaded. On the order site for fi they list a 08 an 09 model. Since I'm not the orginal owner an don't know if they are the 08 or 09 how can I figure out what they are. Does it really matter can someone tell me the differences between the two. Thanks guys an gals

So I finally had finished my box, got my amp and my subs came, I was just waiting for the opportunity to install I got it all hooked up and no sound... After some trouble shooting- I hooked up an old amp and speaker to make sure all my power stuff was ok and my head unit was providing signal and so my old amp and speaker worked fine... So I replaced the amp thinking that was the problem and I am still having the same issue... So either there is a problem with my two BLs, a wiring issue, or an amp settings issue... Heres the specs on my system I hope you guys can shed some light on my situation... Thanks 2 10 in FiBL 1 Ohm DVC Hifonics BXI 2608D Kenwood DNX 5120 Headunit S…

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!

Fella's, I am running 2 BL 12's in a ported 4.23 cubic ft enclosure tuned at 33hz. Is this enclosure large enough for the BL subs? The enclosure is 1" thick all sides, braced inside 1" thick and has a 2" front baffle so i know its strong enough.

So the plan is to buy 2 Fi BL 12's dual 1ohm, with the cooling option and flat wind what is the new rms power rating (approx) I know it depends on the enclosure so optimal ported at 33hz. In a Jeep Grand Cherokee I plan on running the two on either a Re audio VLX-3DE or Hifonics BRZ2400 (2400 watts)

OK so i have a hifonics 1606 powering one 12 Q and i have the gain turned all the way down and the multi meter is reading 36.6 volts and if i turn the gain up to about half way it reads like 55 v. i am confused and my headunit is only 2 v preouts what is goin on, is there anywone that lives in so cal that can help me set my gains and check my setup because i am either just plain stupid or something is wrong.

My BL just stared making the noise yesterday, the sub is hooked up to a MTX TA81001. The gain is set at little over half. I really hope the voice coil is not going out.

I have one SSD10 D2 with copper coils in a sealed box with about 600 watts rms coming from a Phoenix Gold Ti600.2 I know going ported will give me more output but i'd really like to stay with the sealed box I have because it fits perfect in the truck. So, i've been looking into getting a 1000 watt amp like a Sundown 1000 or Alpine PDX 1000. Would this upgrade be worth it or should I stick with what I have?

Well i received my 12 inch q in the mail about 3 weeks ago, was packaged with much care and got here in a timely manner considering the holidays, thanks fi. The sub is in a 2.7@32hz box, sub and port back. The Q is being pushed by a US Amps XT4000d(1500rms@1 ohm), so it's getting all the power it needs. The Q gets fairly loud and sounds great with different types of music, but I'm just not getting the lows that i was expecting after reading all the reviews on it. Songs like soul survivor and the low note in hypnotize just aren't being played with authority. I know that there is supposed to be a break-in time with this sub, but the suspension has loosened up since the firs…

i would like to ask about the best enclouser firing direction for this truck? i have a 4 cb. box tuned to 32 hz. sub and port facing the same same way, but facing it forward it puts the port to close to the back of the seat and firing it up flexs the top unreal! can anyone help me with suggestions on a goob enclouser build for a silverado ext. cab truck with a loaded bl 15 on 1500 watts? music prefrence is rock and rap bass tones... thanks for all suggestions...also i would like for it to be loud and hit hard as possible and keep the enclouser size to around 4 cb. tuned to 32 hz. again thanks...

I bought a pair of the 10" BL's with the SPL option a few years ago, maybe 4. I have no use for them anymore as a burp only sub. Is there a way to change them to a musical and burp sub without having to change motors? I know the gap is pretty tight since it's a burp only sub, just not sure if it's as simple as buying a new recone or if it's more expensive.

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

My buddy bought a Triple stacked BTL (first gen??) and I currently own the 2010? UFO style BL (without red sticker on bottom of magnet). My main point is will it be worth it to get his BTL? Im not sure how much of a difference the generations actually make but I'm assuming a newer generation BL will perform the same as an older generation BTL. Opinions? Im going basically for SPL and the box is 3.75 ft^3 @ 32 Hz. Please no flaming. Im already one hundred percent satisfied with my BL but just wondering if the BTL will give me that extra boom boom ya know. Ohh, and both the subs are fully loaded 15's and will be ran off of my RF T-1000Bd.

My Q15 peak is 39 htz and i didnt know if there was any good songs anyone knows cause i need one for my fist comp cause i cant use sweeps, test tones, i have to use a daily song?

i'm debating on weather i should run my pcx2400 (800rms x 2 @ 2ohm) To 2 FI Q 10" dual 1ohm subs, in a prefabbed under seat downfire box, sealed .55cubes ea. (subthump.com) http://www.subthump.com/chd.htm OR build a custom box and remove part of the backseat ported 15 or 18 FI BL Dual 2ohm with the PPI pcx2400 1600w RMS x 1 @ 4ohms. in a box built to spec. problem with the big ported single sub is i'd be losing half the backseat, and would be visible by just looking in the window. I'm open to different sub/box combos using the ppi amp. console? blow through? behind the seat? 800x2 @ 2 or 1600x1 @ 1

hi, i just receive my BL and noted that there is a plug on the pole vent. Shall i take it off? here is the pix : http://s291.photobucket.com/albums/ll314/_...nt=DSC00241.jpg thanks.

Sent an email, and with all the set backs I've heard about with the email provider you use, I thought it might be easier for you and me to put up a thread about it here. It's a 15'' and I would like d2 coils. Was just wanting to know how much it would cost, and if it's possible to get the person whom I'm trading with for it, to ship directly to you, and you ship to me. Thanks, Jonathan

Well guy im new to this forum so Hi . Now to the question... I have just bought an 18" btl fully loaded with the spl option, and from what I read on here you cant play music at all with it wich is not my intentions. I want to be able to play music and not just a tone. I have just emailed trying to get my order changed to the Daily option. If it dosent go through will the Spl option really not be able to play my songs at all? Im really hoping I just didnt waste 500$...

I have 2 15s btl. 1 is dual 1 ohm, measured 1.5ohm on each coil.(working) both 2 magnet motor. 2nd is d2 , measured 2.5 ohm. (blown) d1 sub, the pole is black color , i think that means its universal. d2 sub blown, doesnt have black colored pole. Question is can i recone d2 with 1 ohm recone kit to match my other btl, and will they have same specs? plz help me out.

I have experience with a ported 12" BTL (2500RMS amp) last year. and a ported 12" BL (1500RMS amp) before that. Figured I'd save up a do 2x15" Q's with options in a sealed enclosure. Would a 2500RMS amp be enough, or would they require more power than that since the drivers will be fighting vacuum? Recommended size per sub is 2.0-2.6sqft. Goal is to slam the lows, should I aim for a smaller or larger enclosure. Also, what's recommended for dual drivers, separate or shared internal space?

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.

it was making a popping sound a few days ago. then yesterday it happened the coil broke from the cone. im going to try in glue it back witch glue should i use ?

Well I looked around to see if I could find the new specs of the 08' BTL. I couldn't find it, so if anybody could help me then that would be great. Thanks

I was driving to San Francisco today listening to music in the car not all that loud and about 3/4 of the trip I noticed that the brakes started to respond slower. For example, I'd press down the brakes 1/3 of the way down and it won't respond until I press halfway down until the brakes even start working. By the time I arrived in the city, I popped the hood and I noticed that the wires were coming loose from the fuse holder. What's even worse was that the wire was in contact with something metal and I saw some burn marks with something black that melted as well, probably plastic. Anyways, I made it safely, but it turns out I didn't do a great job with the wiring. Althoug…

I Have 2 12 Inch Fi BL's and i dont know what amp i should go with i was leaning towards a sundown audio 2000D but also was looking at soundstream PCX 2000D .. any suggestions on what i should do ?
