Fi Technical

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

Im looking to get some floor work done in my trunk in LV and need some good recommendations of good audio shops in the Las Vegas area. Figuring FI is in Vegas, i would hope some of you would be able to give me some advice. Thanks

I want to build a sub for home theater, using 2 Q15s in one sealed cabinet. What modifications can Fi make to optimize the Q15s for home use? I'll need a complete listing (including Le inductance) of the modified T/S specs for my modelling. Ideally, I would want the drivers to be optimized for a sealed cabinet volume between 4 and 7 cubic feet. Thanks.

is it ok to trace around the inner black gasket ring that comes with the subwoofer to get the size for the cut out hole?

has anyone use these before to build a box and how was the out-come? and if not would yall use them to make one?

Was wondering if those cut sheets are still optimum to today's Fi Q12?? I'm purchasing one at the end of this month and would like to build the box while I wait for delivery. Going for a ported enclosure but for fun was gonna build a sealed too and check them both out. Thinking of getting the sub fully loaded with every feature just cause I can and run it on a Q1-1200D from Soundqubed at 1ohm producing 1200watts. It will be in a 2005 jimmy 2 door so room is not a factor. I listen to all types of music and would love clear crisp bass but also able to bump it when I feel like it. I know there is no magic box that gives me both SQ and SPL just want good sounds on musical mu…

ok so I went and measured my trunk, the room I am working with is 36" wide, 20" deep, Now at the front of the box the height is 17.5" and at the rear the height is 14.5" Can anyone design me a box with 3.9cubic ft?? or where can I go to see some cut sheets of how this will look, I know it will be slanted front the front to rear.. this will be for my Fi BL 15.. thanks for all your help

Hi, I am currently having someone build me a box and they are looking for a cut-out template to cut the hole for the woofer. I gave him the cutout diameter but he wants a template to be sure. I can't seem to find one on the website. Do Fi offer one?

i know this is a real noob question but what is the cutout diameter of a btl 18"?

I just added the D1 copper coils to the SSD series. Previously the copper coils were available only in D2. The addition of the copper coils to the SSD subs adds a bit more SQ in some applications. It also allows the subs to play deeper in the same sized enclosures as the standard aluminum coiled SSDs, or have the same response curves in slightly smaller enclosures. Thanks... Scott

Looking at the BTL SPL vs Daily Option.. I would like to use a pair of 15"s mainly for SPL competitions, BUT i would like to squeeze JUST a song or two out of them every once in a while.. They are not to be used as daily play subs.. my question is, would i be able to get away with playing music for a short while with them, with the SPL option, or would i be better off using taking the daily option instead.. thanks

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 am debating if I should dampen the custom box when I get my 12 fi bl 2ohm. Also what do you guys think about powering it with a PDX 1.1000 at 4ohm ~1229 rms?

to whom i can talk to about dealing this product " fi car audio" here in our country? i already emailed it at [email protected] but still no one's answered , hope some one could talk to me about this. thank you very much

how many decibals are you you guys hitting with your Fi BTL 18"

right now i have 1 12" ssd fully powered in a ported box. it is 16X22X14. it sounds good and i listen to almost everything from rap to techno. I was wondering if it would be better to switch to a sealed box? i mean one advantage would be less used space. and which direction should i face the box also...

Hey guys, bottom line is i have designed a few enclosures and they sucked. I'm not so bad on the building part, just the calculating port length and area and volume and stuff. I have a 15Q and was wondering if someone could design me a box of around i dunno 3-4cubes tuned to like 30-33hz. My trunk limits the box to be like 16-16.5 inches tall (otherwise it won't slide in) and uhh yeah thats the only real limitation. Thanks in advance.

Details - Fi Q12 Ported - Down Firing - 2.0 cu.ft. Net Volume - Port @ 33hz, Amp Tray Additional Detail - Due to the spec's required relative to the size need customer is willing to raise the rear seat 1.5" and the enclosure protrudes past the front of the seat edge 2". Again, Thank you Scott for the measurements for the Q12. Best Regards, Phil Woodlawn Cabinetry

I took the plunge and bout a BL 12 with Cooling, Flatwind, and Internal Leads. It will be powered with a MB Quart MB Quart Q1.1500D giving it 1500w RMS @ 1ohm. I now need to design a box that will fit in my trunk. The cutout that they have listed on the forum might work in my trunk but I would like to design one myself. I was thinking somewhere between the 2-2.5cuft (after sub and port displacement) and a slotted port tuned to 32Hz. It seems that every online calculator gives different results or has a cuft value that is crazy high. I was wondering what the actual formulas are for finding port length given the port area and desired port tuning? and any other formulas /…

Just what the topic says, i need to know the diameter of a BL 12 magnet.

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

Besides the voice coil, what are the differences between MT and BTL softparts?

ok im trying to figure out what to run for a build im about to start. if i had 4 18' ssd's w/ bp power and flatwind and 4 "stock" bl's in the same car, box, and tunning is there gonna be a major difference in loudness, sound quallity.....

Got a 12" Fi BL that needs reconed but was curious if I can recone with a totally different brand ie. Incriminator, Ascendant, Sundown, DD, etc

I bought 2 used UFO motors and they are different motors completely. The one has "cuts" in the side around the slug in the black part and the other is just smooth.plus they seem to be different sizes? I already ordered the single slug recones. Are they OK to use together
