Fi Technical

Hello all been reading this forum for a while no w not new car audio but new to ported boxes trying to put one 18" fi btl fl into a scion tc with out taking up back seat. The measurments I have are 40"w 16"h 21"d I would like to tune to 31-32 hurtz. Iwas wondering if this would be enough airspace and if someone could help me with the deminsions I would greatly appreciate it. Oh and also going to power this with an saz3000 sundown if thats any help. And Thanx in advance

im picking up a 12'' bl and i read the best tuning for is 32hz, can i get some box designs to hand to the audio shop thats building the box? this is my first time going with ported and i know nothing about vent area and how many sq inches of port..so i could really use some help..90% of the music will be rap but id like it to be musical not just a fart canon or muddy, it will be a daily driver

hello guys, ive been a member for a while and have read tons of information on the Fi Bl and im ready to pull the trigger on one, but im stuck with one question. I've viewed the cut sheets that are located as a pinned topic, but i was wondering if i could make a slight modification. Since i will be building the box as a center console in my crew cab truck, i will be downfiring the sub and wanted to move the port to the side firing forward. The only reference i can think of on how i want the box to look is like the DD high efficiency box with the side port. Now my question is, am i correct to think that it will be fine and that all i need to make sure is that the port len…

I am selling my MD2, and I have a 40.1 sitting there for when my 2 other Q15's arrive and get installed. My questin is... If I am careful with the gains, is it ok to run only 2 Q15's on a 40.1(rated @ 3600w rms @ 1ohm)? Or should I just wait until I get the 4 pack installed?

Just ordered my 15" SSD and cant wait for it to arrive. Now on to buying an amp for this little beast. It will be going into a 2008 Nissan Frontier 4.0L V6, enclosed in a 4.2cf. Ground Shaker box. My main concern is how much this sub can handle. Its the Dual 1 Ohm version along the flat wind coil option which Ive heard ups the power handling. Ive been looking around for an amp, Was looking at the Kicker zx1000.1 which puts out about 1100-1200W RMS, the MTX Xthunder X1000D, and the Alpine MRP M1000 all puting out similar rms W (1000-1200). I would like to go with the MTX for the reason that it is on sale for $269 on sonic. Ill include a product list below along with the mo…

Hi im gettting a 12" q and i was wondering if this could be done? I just dont want to worry about tinsel slap and i kind of like the look better thanks

How much is one of those shipped to 68510? Also before you build it is it possible to have you guys put the biggest lead wires on there (like the ones you shipped me), because When I took mine apart to fix the wires it worked fine but the copper wire broke right next to the coil, and now I have no copper wire to solder the lead wires to. let me know if there is a way to fix this problem. Also would it be possible to send you the sub I have and get 2 10" Q's and a little bit more money in exchange? I think that I am going to go for sound quality this year, since I have a bigger car now. thanks Chris [email protected]

Ok, so I already have a Fi Q that I have been bumpin for about 4 months now. I am planning on getting a second Q after X-mas. Should I recon my broken in one before throwing it in a box with a new woofer? Also, what would be the total price for a recon kit with is being sent to 95677. The sub is a Q 18

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!

yes, i searched. my sincere apologies if someone has asked this before. i am planning on buying a single 12" D2 SSD or Q... which one is yet to be decided the amp is a hifonics 1206d, an alleged 1200w rms but closer to 900-1k probably. stock electrical + big three already built the box, ported 2.25cubes@34hz so.... i want to make sure the sub sounds good, i know both of them will get plenty loud for my tastes, but my main question is, if i get the copper coils does that reduce the rms rating of the sub? do the CC's really make taht big of an SQ difference? the reason i'm asking, is becasue the FW coils improve the power handling at the expense of some SQ, so i didnt kn…

This is my original plan and am wanting to make sure this is my best option for Loud and clean bass. I was used to running 1 Audioque 15" ported at 29hz in 7.5cu ft box off of 1400w, it was ungodly! Current setup - 1 Audioque 15" Sealed in 2.2 cu ft off of 1400w. It is a little less loud in the low frequency area due to a lot lower group delay as well but like how it sounds as well. Anyways, my current project is to have 3 12" Qs off of 3 optidrive 2000ds. Each q would be wired to 0.35ohms all in a common chamber sealed box roughly 2-2.4cu ft stuffed with polyfill (emailed fi about this to see what they say bout the polyfill). Now, these amps are rated at doind 1,600w at…

I cant decide wether to go sealed or ported with my 15" Q...I listen to mostly rap and want good sq bass but at the same time so good loud hard hitting bass...whats your guys vote?

I have 4 18 inch fully loaded BTLs that I will use for a daily driver. Can anyone help with how many cubic feet each sub should get? I want a ported box and will power them with 2 jbl a6000 amps. The manual says 5- 8 cubic feet but what size should i go with?

I was really hoping some one could help me out with blueprints or a layout for the idea enclosuer for this sub int he space i have to work with. car is a 96 cadi fleetwood brougham rwd i measure it out and The max demensions are H 16 W 42 L 28, i would like a box with 45's in it if possible. i only listen to bassy rap and r&b jezzy,gucci mane, etc for examples. ported obviously tuned to 32hz? again this if for a 15 FI BL fully loaded help woul dbe GREATLY appreciated.

Ok I'm picking between the lanzer opti 2000 or 1400. Based on the specs at a 1ohm load with the 2000 I would be getting around 1600 watts "give or take" running to the sub right? With the 1400 the max is about 1300 but I would expect like 1000 or a little around 1000 like 900 something at 1ohm. Which one would u guys pick between the 2? Just for reminder I have the Fi Q 15 with bp option Man reason I'm asking is I don't wanna over power my sub.

hey can i get a price for two 18 recone and basket for re sx shipped to 38112

Hey i blew my speaker and i been sending FI emails and myspacing them, but i haven't heard anything from them. Anyone know how to go about sending my speaker to them, or how to get in touch with them, like a phone number, or something.

I just built a new enclosure and was wondering if 118 inches of port tuned around 31hz ok for my 4 fully loaded BL 12's?

Can someone post some pics of the extreme leads? I'm curious to see what they look like lol.it would be greatly appreciated.thanks!

do you think it would be fine for a 15 fully loaded btl to handle 2 sae 1200 on each coil at 1 ohm i did this with a solo x 12 before it hit hard

Hey, I sent in my sub over a month ago. I tried getting ahold of Fi to let them know I never included an email or phone in the package because I forgot. What's going on with my sub? I should have it back by now? TIA

Well I am gonna be going for my first recone attempt. It will be a BTL. I am feeling pretty confident but have a couple of questions. First thing How do I properly clean all the excess stuff from the original BTL. Like the surround on the basket and where the spider is glued down at. I was told just a heat gun to get it loosen up so I can just pull it all off? Second I hear alot of people talk about the "Triple joint" and how well that is glued. What is the triple joint? Also I am confused on how to properly "shim" it. Is it that the shim alligns it properly so that it doesnt rub? If so that means the paper shim is only making like a hairline gap? And wheres the best pl…

I am wanting to know if these numbers are sufficient for a vented enclosure for for a 12" BL. I will have it hooked up to a MTX TA81001 A 1 ohm in the trunk of my 06 Honda Civic. Any suggestions would be greatly appreciated. Width: 36" Height: 18" Depth: 15" Port Height: 16.5" Port Width: 2.5" Port Length 1: 11.75" Port Length 2: 6" Total Port Length: 22.25" Port Area: 41.25" Internal Port Volume: 917.8125" Port Volume Displacement: 930.5625" Box Volume: 3.909 cubic ft Tuned Frequency: 32 Hz

Hey guys, Just wondering if you think I may have made a mistake with the 2 15's I am trying to squeeze into my car, I have a decent amount or room to play with... but do you think I should have went with 2 12's instead? Or do you think I should just throw the power at em and let it ride... My box will be around 8 cubes. My trunk is actually around 17-18 cubes, it's just that it has a tiny opening... do you think there will still be enough room for the air to move around in it... Thx Josh

Got my car back from the dealer service dept. and my 10" rockford T2 was fried. Rockford doesn't offer a recone and the parts distributor that they referred me to says they have a really long back order on parts. I was wondering if it's possible to do anything with it? It was a pretty decent driver, and i would hate to just throw it away if there is an alternative. thanks!
