Fi Technical

im looking for a ported box for the trunk of a 95 caddy, 14"H 14"D 38"W is the max for the box. it's for a 12" ssd how long/big should i make the port to tune it around 33Hz's it also going to be powered by an alpine 650 watt amp.

i bought a mt motor a few weeks ago and ups damaged it....the pole has shifted to one side........can you fix this? or is it a 53 pound paper weight?

I was just wondering if anyone knew of any good car audio shops in Ohio (Columbus would be best) that have worked with Fi audio before and could do a custom wall for 2 12" BTLs and probably 2 TD20001 r/f amps. I like competing in meca's car shows (SPL) and i don't think i should do the box like originally was going to. Thanks

I want to get a btl 12" dual 2 for my gp3000d pro amp. I just don't know if it is recommended to get the 3rd magnet and HiXMcoil options. please help asap. thanks!

I have been looking at getting a fi bl 15 for my 2002 nissan sentra and was wondering if i could fit the box needed for this sub in my trunk? Also what options should i get i want the real low deep kinda bass? and what amp would be best for my budget i would like to stay under 500 for the amp and im not sure which would be best for me and where i dont have to do the big 3 any ideas or help would be great thanks

I'm lookin to run a pair of Q 10s eventually but I'm just wondering if anyone has experience using them in a smallish sized ported enclosure? .7 cubic feet to be exact, 10 sq inches of ported, tuned to 30hz...per driver of course. Thanks in advance.

Did you guys start using different tinsels now on the btl?

Hey i just wanted to know what would be a good enclosure for SPL with 2 12" BTLs.... I Drive a 2003 Tiburon GT and do wanna be able to listen to music occasionally. Thanks for the help

Hey Scott, been a while... once again need your services for some recones, starting off with a standard recone for an RE XXX 15" (old style '05) with 2 spiders and DVC 1.4 coil I have a few more parts I need, a bit of a list, let me know if u prefer an email about it ill check back here later

Car: 95' Lexus SC400. Driver: 1 or 2 Q's. 12s? Here's the deal, I'd love to do 2 12" Q's in about 2.8 cubes sealed or so. If I can make it fit. OR, I can do 1 12" Q and port it, but at what cost to SQ if the box is built properly? 1 Ported would yield a slightly smaller box if space is as much of an issue as it could potentially be once I tear out the false wall. The problem lies in that there is a Factory 10 and 2 4" in the rear deck, I think. 10 for sure, not 100% on the size of the mids there. The rear wall is steel with the gas tank there as well. Again, I have not had time to tear this out but I know there is at least some room in there because I've seen pic a…

I was wondering if 140in of port is to small for 2 of the Bl 18's? When I build my box the port would be 20h x 7w x 12d that would be 32hz. The box would be 40h x53w x14d. Should they be tuned lower or higher? Thanx Jason

I haven't ever designed a ported box before, but I did alot of reading and sat here for a few hours and came up with a design for my enclosure. You guys wanna check and see if I did it correctly? will be using 3/4" MDF. Outer dimensions: 29.5" width 15" height 15" depth Inner dimensions: 28" width 13.5" height 13.5" depth Volume = 28 * 13.5 * 13.5 = 5103 cubic inches convert that to cu.ft 5103 / 1728 = 2.95 cu.ft before sub/port displacement Port dimensions (which I hope are correct): 2" width 13.5" height 20.53" length Port volume = 2 * 13.5 * 20.53 = 554.31 cu.in convert to cu.ft 554.31 / 1728 = .32 cu.ft so... 2.95 minus .32 minus .15 (sub displacement) = 2.48 cu.ft I…

What is the lowest amount of watts to feed a 12" Fi Q and still get decent/good performance? I'm shopping for an amp and want to see what my options are.

i am willing to use my whole trunk if necessary...you guys think it will fit?and sound good....i already know it will look good that thing is huge haha....also ...how should i wire it?...i have a t8002 for now but i am going to upgrade real soon...i bought the dual 1...any tips?

I'm looking at picking up 2 SSD's (15"), the box will be roughly 7 - 7.5 cubes. I would like to find out what the optimal size for the port. Still deciding between slot and aero, might need some suggestions there. Let me know the dimensions of the port you would use for mainly SPL in a 7.5 cube box. Thanks!

So I got a 15" Fi Q for Christmas. Everything else that I need for my system I have as well. The only thing that is missing is a subwoofer box. Originally to save some money I was gonna build my own sealed enclosure. But after talking to some of my friends and family I decided to get a professionally made box. Here's the problem though, the only site that I've managed to find is, www.klausaudio.com. And while the site looks great and the options for customizing your box is superb, they're not taking orders right now. (Or responding to my frickin e-mails...) So I wonder if you guys knew any other respected custom box dealers/makers. P.S. Since I want a sealed enclosure I w…

Hello scott or nick, I need a Recone for my 18" Fi BTL. Its Universal, daily, loaded. I need A Dual 2 ohm VC with the HiXmcoil, shipped to 53597 (I hope Im the only one with a BTL in Waunakee ). Let me know what I need to send you, and where to send it to. My Email is [email protected] or PM here. Thanks - Shelby

Does any1 have a 12" Q in a sealed around 1 cubic feet? I want to know if the q will get loud in a sealed. Im thinking of replacing my 2 JL 10W7 with 1 12" Q or maybe I should just power 1 JL 10w7. The 2 w7s take up my whole trunk and i just want to get some of my trunk back. I have enough to put a Q in a sealed enclosure but have around 1.5-1.7 cubic feet for ported. My amp does around 800-900 watts at 4 ohms or 1600watts at 1 ohms so dual 2 ohms it is. Should I just keep 1 of my jl 10w7 and port it? Will that sound close to a 12 Q sealed?

I really need an RA# for my bad sub. I have called and sent numorus emails but have received no return contact. I have been emailing and calling from December and even tried to find you at CES. Please someone contact me so I can repair my sub. I have all receipts and have all the emails dated to show I tried to contact you before my waranty expired. Thanks, Mel.

How loud will his be, haha. No but seriously - I was considering purchasing the 6000D because i can get one for only $100 more than the 4000D. I was going to use the 4000D for these 3 10s but hey, why not go with this one, you know? I am not going to deliver that much power to these subs, that is the point to this topic because i will not have the battery power to support the 6000ds potential. The question pertains to the BL's cooling option- Fi says as long as you do not burp the subs then the cooling option is fine for daily. I am planning on setting the amp up to output a real 4,500w(peak spikes) as if i were to have no voltage loss. Sometimes i show off setups usi…

I have a Fi Q12 in 2.5 cubes tuned to 32Hz. I dont like the way the box was made so im gonna make a new one with left over MDF. I have max demensions of 38 wide, 14 height, and 14 depth. i still wanna tune it to 32Hz but in a smaller enclosure like 2.1-2.25 cubes. So any plans will help. Need 12-16 square inches of vent area per cubic foot of volume. also what difference would there be in a smaller box?

can anybody help me with box design? i was just gonna make a box similar to the one i have in my escape for the ssd 12's but i kinda want something a little better. i listen to every type of music from bass music to jazz to rock. so the box would have to be versitile. the twelves only have copper coil option. i need help because the space is limited. i have a huge trunk but for some reason benz decided that was also a good place for the gas tank and spare. i am thinking that the port(s) should face up through the space in the rear deck that will be cutout. i have two sets of max measurements because one way the box would have to partially cover my amp and the other way it…

im just wondering if it would be possible to have softparts assembled to work on a fosgate power hx2? i can take exact measurements if needed, but from what i can see so far it has a 4" dual 2 ohm coil and an 8" spider like i said though i can take better measurements of everything if you guys can help me out on this one. btw i have tried contacting RF direct and they stopped making softparts for this particular sub seeing as though its over 3 years old.] TIA chris

I'm looking for specs pertaining to a STRICTLY SPL setup using two BL 18's. What should the port be tuned to? How much airpsace do you recommend if I'm using a single chamber and acoustic coupling?

If I choose to invert my subwofer so that the magnet is outside of the box, shoould the box be any different than if it were mounted regularly?
