Fi Technical

Hello all. I am currently running my 10" Fi ssd woofer in custom built ported box (sub up/port back). I love it! I have a kid on the way and would like to switch to a smaller sealed box for more space. I have a couple of questions: 1. Can purchase a prefab box that meets the recommened specs? 2. What size would be optimal? .6-1 cubic feet is what is recommended but would it be better to stay on the .6 side or the 1 cubic foot side? Thank you in advance...

Hello all I have just received 2 FI Q 12s dual 2ohm subs. Now I am having all kinds of battles with self over what to do with them!! 1st issue is my amp is a Memphis Belle 5ch. If I run both subs, my wiring options are .5 ohm, 2ohm, and 8ohm. The amp is not .5ohm stable, only has 600watts at 2ohm, and not sure what it would be at 8ohm(only 400 at 4ohm). Would 600 be enough watts for 2 subs?? I have a Trans Am so if running both, I would have to have a sealed box. Is this doable without changing amps? I have been thinking of just running 1 sub and selling the other. If I do, I could choose a sealed or a ported enclosure. I have read the sticky about enclosure size my qu…

i currently have a crossfire vr 2000d and an optima yellow top with a kinetik hc600. running 0 ga from the battery then 2 ga from the kinetik to the amp. im currenty upgrading the "big 3" and am looking at an alternator around 200 amps or so. is that enough upgrade to feed that amp? the type of subs i was looking at are the FI BL15's which are 1000w rms and also the RE AUDIO sx15's which are rated the same. also if anyone would recommend an enclosure not only for daily but for comp. as well....probably somewhere along interchangeable ports

My new box will be 4 cubes at 30hz, with sub up and port facing the tailgate in my blazer. (5 inchs port to tailgate) My running it with a sae-1200d So my question is, is this box too large?

im looking to get help designing a new box for my 18" ssd. the box is going in the back of my 00 expedition with the 3rd row seat gone so space isnt a problem. the amp is a rockford t1001bd. specs for the sub say 6-10 cubes 32hz. should i do the 10 cubes? or smaller? and am i better off running the 1 sub at the full power of the amp ( birth sheet says 1400 rms at 1 ohm) or running 2 18s and dividing the power? also if i did go with 2 subs what kinda cubes should the box be?

Hi, i have a blown tensil lead on my X 12 and i was wondering if Fi could re cone it or replaced the bad lead. This isnt my first blown lead. Before i replaced them but in removing the dust cap i cut through my cone, so i'd rather send it off to Fi. Does Fi cut off the dust caps for this kind of work? or just recone the sub? If a re cone is needed to repair the sub, is there a recone available???? Thanks!!!

which of the old 3 slug options were cosidered basically universal, D1 or D2. i bought my btl from teampsi on ca.com, on his ad he said its a D1 so its basically universal. i have read else where that the D2 were the ones considered universal. can anyone clear this up? im about to order a recone, and i want D2's but i want to make sure it will fit! thanks fellas

Can someone post a blue print of a ported box for this. my friend said someone was going to build me one for the past month and nothing has happen yet so i figured if someone could just post a blue print i could build it my self i was looking for something tuned around 33 hz. can someone get me dimensions and all that good stuff. thanks for hepling.

ok so i have a 98' chevy blazer s-10 and im going to make a 10 cuft box but i need to know how much space the brackets and braces will take up and what size MDF should i buy??

Im looking at getting 2 subwoofers. Trying to decide between the SSD10, SSD12, Q10, or Q12. This will be a sealed with about .9 to 1.2 of airspace-haven't decided, depends on subs. Between the SSD and the Q which sounds better sealed/louder in sealed. What options would be best. I have read the descriptions of the different wires and still dont know what peaking is meant to be. -what effects will the flatwind coil or copper have on the power handling and sound quality and loudness. Peaking? better for sealed? -Is the BP option worth it in sealed. Will any of the options help reduce the subs heat in the seal enclosure. The subs will be sharing the power of a kicker zx…

I just ordered a 15'" bl. I order a dual 1 cause I wanted to run 1ohm. I forgot that with 1 ohm you can only got to 2 or .5. If I get another bl dual 1 could I wire it in a (series/parallel) and get 1 ohm. Thanks all

Due to tight angles I need to know the OD on the Motor for a 12" BL. Thanks

Hi, i'm buying 2 Fi BTL 18's and was wondering how i could build a ported box. i've never built a box before so i need a lot of help. If you could tell me what i need to buy and how to do pretty much everything to build this box it would be great. Thanks

http://www.subwoofertools.com/calculator_d...mp;sheet_size=0 would this enclosure be good for 2 12' fi Bls if not then anyone have a good design that they like to share or does anyone have all the specs on a 12' fi bl

I seen this guy on youtube with 2 18'' Fi.SSD's on 2400-2800rms in this box below hitting 149db.

Well i just ordered 2 12' Fi Bl Thursday, and well which leads me to a off topic question how long will it take to actualy get it in the mail if i live in texas, and well i was wondering if anyone has a blueprint or something so i can make a box out of it...

Hi everyone. im just stoppin by cause i was wondering how much it would cost to get a recone on a SSD sub. thanks

I just got rid of my suv and bought a car and I plan on putting my Q in my car but don't want to use the same box because it's just too big. Right now it's in 2.5 cubes at 32. I was thinking about going sealed for SQ but then again I want it to be loud enough for the sound to come from the trunk into the cabin of the car. I'm a low end feind, so I definitely want the lows. For a mixture of SQ and SPL while retaining some trunk space I was thinking 1.8cuft (FI recommended minimum) tuned low to like 28-30. How would this work compared to going sealed in 1.5 cubes?

it doesn't make sense, when i chose the p chamfer option it added $10 then i chose the cooling option too and it doesn't have a price. and there's a note that it i chose both p chamfer and cooling, uncheck the p chamfer because p chamfer is incuded in the package of the cooling. in short, if i get both options, the p chamfer and the cooling, i will get it for free, but if i only get the p chamfer option, i need to pay addtl $10 for it. can someone explain this for me, thanks. i'm also planning on getting the universal option, my question is, if i get this option will there be any changes in the performance of the sub? or side effects?

I have a fully loaded BTL 15" and it got here yesterday. I had one of those cheap prefab boxes laying around so i popped it in and put 1200 watts to it from a hifonics amp. Wasn't quite what i was expecting. My friends two 12 inch mojos hit way harder than the BTL. I'm not trying to put down FI or anything i just want to know how i can improve the sound (loudness) of it. How much better will 2000 watts RMS to the btl and a much bigger box help? my current box is only 2.3 ft.^3 Heres the dimensions of my new box.

Will this enclosure work for two 15" btls

i know this will sound stupid but what is a dustcap? is it the cirlce on the center of the sub? the one with the fi sign?

scott or nick, or anybody else that knows i have a question. i have two 12's that i bought in germany and being the dummy that i am i dropped the box they were in and one of them completely broke the basket all the way around! the woofer is still good i was able to line it up and push down and the voicecoil isnt damaged all the surround and wires are still attached. the speaker looks like it has almost the same basket as my fi 12's is it possible to take the woofer and replace the basket so i don't have to buy new woofers yet?and if so can you guys do it? or can only certain speakers be re-attached like this?

questions: what do i do to get my 15 reconed? how much will it cost? and would it be kinda cheap?

what happens when u tune a TL box lower than the drivers Fs ? for exampl the driver in question has an Fs of 26Hz and I would like to tune @ 20Hz besides the obvious wavelength being longer.... does the driver/box not perform quite as efficiently as one with an Fs of 20Hz? btw: how do I test the Fs of a sub ? I have a DVM and tone gen available...is that enough ? thanx guys
