Fi Technical

I am hoping some one can help me design a ported box for a single 12" Q I am going to run it off of a DLS A6, 1200 watts rms x 1 @ 1 ohm the DLS amp only has a subsonic filter fixed at 25 Hz. The dimensions that will fit in the trunk of my 2003 Nissan Altima are: 33" Length x 14" Height x ? Depth is the only variable my front stage consists of DLS UP6 (6.5" components, mid in doors and tweeters in A-pillars) the front stage is bi-amped and ran off of a Tru Technology B-745 ( 100 watts rms x 4) my goal is for the sub to blend well with the front stage and to sound musical and dynamic.

I'm getting a Fi btl 15", could I please get some suggestions on a variety of amps i could use to push it . Thanks in advance

I broke one of the terminals on my BL 10" yesterday when I was pulling it out of its box. The tinsels are fine and the sub is still working perfectly. But the terminal is moving up and down! I am thinking it is going to start vibrating once it gets moving! I dont know how Fi had it secured, I am thinking it was glued down, if so, what kind of glue should I use to reglue it?

Im making a box myself but im having a little dilemma im my box construction... i have a 4.35 cube box... im plaing to make the port 2.75 inches wide.... im just stuck on the port length. iv been using diffrent websites and calculaters, but i they all say diffrent port lenghts... iv used 12volts.com, re calulater, torres subwoofers calculator... im thinking the trres calculater is good, but im just geting a second opinion... can somone help me out with this dilemma im having? the specs are 16 height, 35 wide, 17 depth, 2.75 port width, Length? 21-28 inches... wanting to tune it to 31hz.

What would be good for getting the most volume out of my 10" Fi Q. I want it to go ported for some more output, and it'll be running off of a MD1D at 1 ohm (1200 rms). Thanks a bunch

This is my current box plans for the 1 18"BTL and 1 Saz-3000d I have. I plan on putting all these into a 03 Tiburon(hatch) and competing in spl. Really my only question is would a bigger box better/ is 5.27 cubic feet enough. Thanks box: (outer dimensions) heighth = 16.5 width = 36 depth = 21.5 port: (inner dimensions) heighth = 5 width = 7 length = 10 this port will tune the box to about 34.67 hz which is what i personally like to tune mine to. after port displacement...this will give you about 5.27 cubes of air. so you have room to brace it and not go below the recommended volume. this is also assuming that you're using 3/4 MDF. competition port: (inner dimensions) he…

Just wondering what wiring i should use for FI BTL 15 or 18 power ground etc Thanks

I'm sending in my 3 hp motors to be reconed on WED. I need a addy to send them to. Also I believe its $148 to have them reconed to 18's including shipping each. Correct? So I you could let me know where to send them, and if its ok to sen'd a m/o with the motor, or would it be bast to calll me and I'll pay over the phone with my Debit card?? Thanks, Joe. P Also The 3hp's have the tall top plate. would there be any benefit to miacine cooling channels in the top plate?? Could you do a fully poly cap on the 18" recone(like a havoc), I've seen 1 done, and a 10 with a poly and Fi logo, I'd love to have a full poly with the FI logo. Would look great..

Alright well im going to be getting 2 18" FI BTL's reconed(The older version) and was wondering what kinds of new options I can get like diff dustcap or diff tinsels stuff like.....that Id want carbon fiber if posssible and also what are the prices on diff options...any tips on packing for shipping?

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

Is a 2.9-3.0 cuft.(after all displacements) to small of a ported enclosure for the Fi Q?

in my first thread i stated that i had a mtx tc4001 that i wanted to use. but it woouldnt handle the 1 ohm load that the dual2 would have or it would have a 4ohm load if i ran it in series. if i get a D1 and run it in series wont that show a 2ohm load to the amp?

After speaker displacement I have 2.46 cu ft, I need to figure the port for tuning to 32 hz (recommended by Fi) I was looking at about 28 sq in of port, how long would the port be ? Do I need more port area ? If so what would recommend ? My enclosure is 43w x 14h x 7.5d(combination of top and bottom divided x 2). Thank you for all your help.

scott, been sending some email this past few days, did'nt get any reply is everything ok? pls. check your email...thank you

I have made up plans for a 6cu ft box, after port and displacement. The port would be 4" Wide and tuned about in between 33 and 34hz. If i made the port 5" wide, it would take the box all the way down to 5.1 cu ft or so to be tuned to 34. The port would be 21.5 in tall. It just seems to me that 4" is small, but then again thats a lot of box volume to take up. I'm really hoping i'm just more worried than i should be about port size, and the 6 cu ft will work out. Any suggestions?

Hello, i'm looking at getting a Fi Audio 12" SSD sub. So I was wondering if a square port of 29.25 is alright? My box is 2.1 @ 33Hz. Thats after all displacements. I haven't build a ported box before, so i'm learning how to.

hey whats up i have a btl 18 and a audioque 3500d and i was wanting to build a box tuned at 35hz my max deminsions are H27 x W37.5 x D22 if anyone can help me out thanks

just ordered my bl's and sketching up a box, could i get a little advice if this box will do

Alright right now i have a FI Q12" running 1000 RMS@ 1 ohm (with knob at 10% power) thing hits harder then hell right now, in the past iv always used sealed boxes and when i got this one i got a ported to see what the hype was about I want to get a sealed again but if i do will i lose those super deep lowes or is it the sub itself that makes them. (basicly i want to know will i get the deep lowes with a sealed)

Saw the Q10 is up on website, what is the recommended sealed and ported enclosure size, and tuning frequency for the ported. Thanks Never mind found it Q 10

I decided to back out on the whole 10 cuft. enclosure thing. I finally just realized thats tooooo big so I decided to go down a little. Now I was thinking about it being 8.5 cuft. tuned to 32.hz is that good for low and high notes or what? P.S. Sub,options,amp:18'' Fi.BL:dual 2ohm,Cooling,Flatwind coil,and daily option.its going to be hooked up to a US Amps MD1D thats 1200 rms @ 1ohm (CEA-2006 Compliant) BTW:If you need any more info just hit me up!! thank you:)

Ok so on the 10, 15, and 18" bl the fs for both the d1 and d2 are the same, but on the 12 d1 is 35.2 and d2 is 39.8hz. I was wondering if that was a misprint or if someone knew the reason it was so different. I wanted a 12 d2 for daily but that fs seems kind of high especially when im used to the lows of my q...

im new to the forum and im building a box for a 18"btl and was wondering how this sounded. 33W x 22H x 24D 92^2 ins port area 6.241 ft3 of air space im tight with room so hopefully this is a good setup. thanks

just wanted to let you know scott that i sent you an email yesterday concerning this so you can check your junk mail folder incase it was sent there. let me know if you got the email. it was for a BTL 18 fully loaded. email is [email protected]

I'am going to be getting a box built and was wondering what tuning do you guys think for 4 10" Q's in a 4 cube box? it will be in a SUV and I listen to rock and rap. Thanks
