Fi Technical

this box is for a 12" bl and its gotta fit in my 99 acura el (honda civic sedan for you americans) my link let me know what you think.

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!

I need box plans for a Fi Q12 (dual 2). It going to be powered by a Sundown 1000D. I want it to get loud but also have SQ. So Im thinking tuning it to 32hz. Fi recommends 12-16 square inches of vent area per cubic foot of volume. The demensions I want to use are 14.5 H, 28 W, 18 D. (can change alittle)

I need to recone my BL and was wanting to know if I can recone it to BTL using the double stacked magnet kit.

What are some good amps that can put out 1600RMS at 1 OHM. Please post the price of the amps if you can. Dont want to spend to much.

Hows this sound to you guys. (2)15 Bls Box: 17x39x22 = 6.54cubes (after displacement) Will (2)4in flared ports be enough port area or not enough? suggestions please

Hi, I'm getting a Fi 12" Q and need some help on a ported box. I'll probably go with the recommend tuning of 32hz, but I was wondering what the main differences between 2.0 and 2.5 would be?

does anyone have a blueprint that I can use for a single FI Q 10'' tuned between 28-30hz?

Will 2-18'' BTL's be happy with 2000 watts per sub? And will they play with 2000 watts each or do I need to put 4000 watts per sub? Need to smoke 2-13" w7's. Can 2000 watts per sub do it???

Hopefully someone can help. I found a 3hp motor, but it only has the 4 bolt layout where the basket secures. I've seen a few of these motors rebuilt w/ fi softparts so i know it can be done. My question is what cone assembly, or coils and spiders should I get (assuming I use FI) to make it perform similar to an eclipse TI? Also, what basket should I use, or is there one that I can use with a four bolt pattern? I need some guidance and am a little knew to this so bare with me please, and maybe a price range so I know what I'm getting into. Thanks for the help. Also, when do the new woven tinsels come into production, and will all products be switched to this? It's …

I am truly worried about this since I am eager to get a X10 or X12 and it has to deal with power issues. I have an Arc Audio XXD 2080 and it des 240 x 1 @ 4 ohms when bridged. I truly have been wanting to get a Fi Audio sub since three years ago but would like to know would the amp and the X10 or X12 would work together hand in hand or would it be a total flop?

Ok in 2007 i bought 2 fully loaded 18bls. and had them in my 95 deville. but now i have a 03 and the trunk is a little smaller. right i just have one in with a 6. 75 ft3 box tuned to 32hz. well my other one is just sitting in my room wanting to be build. Ive blown both of them but reconed one couple months ago. but i want to put both in my 03 .the max size in my trunk is 41x40x15. if i keep it at 32 hz the ft3 will be 7.55, i know many will say that would be way small for 2 18s but i already got might as well just make a new box and put it in. My question is would both of my 18s at 7.55 ft3 be louder then just one at 6.75 ft3?

Will a 6" aero port be enough for a fully loaded BL 15 in a 3.5 to 3.8 box

Is 324sq in per sub too large for a striclty SPL enclsure using 4 Fi BTL 18's in a 32cu ft. box

I was wondering if the BP option changes anything on the T/S parameters of any woofer it gets done to? Does it lower efficiency? And if it does, what is the point? Does a subs BL drop by having the BP option?

Whats up everyone. I'm new to this site and im looking for some help with my box build. I just got a Fi Bl 15 dual 1 fully loaded and i am wondering what dimensions i should use to get the most slap outta this sub. I went to RE Audio and used there box calculator and came up with: W: 38" H: 18" D: 17.5"... Port width: 4" port Length 12.75. Second port length: 16"....with 4.2 cu ft. in total for volume. Box is Tuned to: 31.63 hz Does that sound alright? Also im buying a Hifonics BXi 2010D to power the BL so id be giving it 2000 watts. Is that to much? Let me know what you guys think. Thanks

ok here goes we have the box made (except for the ports) it's 19.3 cuft after dis. for subs(3 18 btl fully loaded)and bracing, i still need to make the ports........just to give you guys an idea first i cant make just 1 large slot port would have to be 3 at most (med. size ports)and i would like to tune it around 33-35hz oh and the ports would be facing the same way as the subs it's somewhat of a wall/slant design any help would be highly appricated ............................. thanks ahead of time...........................

i know fi doesn't make the xxx, but the model i have was designed by scott so I'm assuming this is the appropiate place. i searched archive.org -> reaudio.com and came up with no results for the 03 model. anyone still have the 03 xxx 12 t/s sheet by chance?

ok here it goes... and you know i have 2 15 fully loaded bl's dual 1's.... i have the + from one coil to the - on the other coil... on both subs... then + from one sub to the + on the other sub... then the same for the -... from there to the amp...... i should be at 1 ohms correct? or did i mess up should i have gotten dual 2's heres why i ask... im sitting some where around .8 ohms.... not 1. not 1.3.. but .8 thats with the resestance of my ohm, meter the resestance of my meter alone is .1...... so by my messed up math that should put me at 1.1... but hey maybe im wrong...... the reason i am so scared... ok here goes i shopped for months for subs and an amp.....…

i am building a box for 1 18" btl, going to be about 8 cu.ft. (actual is 8.02409) and tunned to 32 hz. i have done the calculations and does a 10"H X 3.75"W x 7.24"L port sound right?

I am set on getting 2 15" BTLs, but I am trying to get some help from you guys on who makes really good enclosures. btw im obviously a noob

I have a mazda ext cab pickup and have about 12cu feet to work with. I really want the FI Q18's. I have never owned a pair of 18's and that's what i want. I want to kind of do what Steve Meade did in his honda and build the enclosure inside of the truck. If i can't do that this is the space i have to work with 30in high x 49in wide x 14in deep. If i built inside i think it would be a little bigger. I was wondering if I can't fit 2 of the Q's, should I just use 1 of the Bl's?

I am looking to run 4 12" BL subs in my SUV and was wondering what would be the best tuning and internal volume for an enclosure that size? Also would it be better with subs up and ports firing back? I will be running 2 Rockford Fosgate 2500-1bdcp amps on this set up.

I was told I can wire this in series to achieve 2ohms. But when I looked up a diagram for the wiring, it didn't make any sense. can someonen post a link of a good diagram? The amp is rated at 1200 watts @2ohms. rms. I figured this would be a perfect match for the Q. Thanks for the help.

Well my computer crashed and I lost the t/s specs I had saved into win isd for my older model 15 inch Fi Q dual 2. I am throwing around new enclosure ideas but the specs for the new Fi Q's seem a bit different. When I use the specs for the 2010 Q it suggest a ported enclosure where as the older one always suggested sealed. I am sure the specs are reasonably close but just the same I would like to get the t/s specs for the older fi q 15" d2 model if at all possible. If anybody could help me out it would be greatly appreciated.
