Fi Technical

I just got 2 more 15 fi btl to put in a 91 blazer. The box I am going to build will be 38" wide 31" deep and 20" tall. I want both subs facing straight up with the port also straight up. I was wondering how big I should make my port. I am looking to get around the 32 hz mark. Also I will be bracing with 1 1/4 inch wood dowels and will be using 3/4 inch mdf.

Does anyone have 2 of these beast in there truck so i can get some ideas?

Can anyone design me a box for 2 12'' fi btls? I have a blazer i would like it tuned around 30 hz any suggestions?

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.

hey, im ordering 2 BLs, i kinda have a design for a box, but need some help since this will be my first attempt at making one here is my plan i got a question on the length to the second port, i used the re enclosure so it game the the first, but does the second port wood need to be directly or close to the center of the subwoofer? and to separate the 2 woofers, do i need 2 pieces of wood or jsut 1? thanx

can someone give my box measurements a once over and tell me if this is going to work,I have 7.49 cu.ft. and i am going to make a box for two fifteen's . I am going to use either the Q's or bl's , the box is going to be ported useing psp flare ports 4"x 17" four of them at this length. is this going to be enough room and are the amount of ports correct to tune this box to 28hz.. this is for a daily driver I listen mostly to rap and R&b. If this doesn't sound right could some one give me some direction, this is my first box build and i want to get it right. any help would be graetly appreciated thanks.

Just currious if the new 12" BTL would be better suited in 2.5 or 3 cubic feet? Would tuning at 32 work or would I be better off tuning higher? Any info would be appreciated

I am getting 2 12" Fi X in a trade and want to know the t/s specs there are none on the website. All I know about them is they are 300w rms and D4. I thought to myself they were perfect for HT. Wire them series parallel and final load of 4 ohms, BASH500 does 500w @ 4 ohms. So, I just need to know some specs so I can figure out what kinda box to put them in. I want to put them in a tline since space isn't really an issue Thank you for your help.

My buddy is trying to put a 18" fi ssd fully loaded in the back of his eagle summit van.. He has about 1200 watt rms of power to run the sub.. There is two different set of max dimensions we can use ( it all depends on how tall the box will actually be. The first set is a tall narrow box and our max dimensions are 27 1/4 tall X 39 wide X 15 Deep. And the other set is 20 1/2 deep X 39 wide X 21 tall. Any help would be wonderful... Would really like start build on box as soon as we can.. Also I would like it ported wit a tune right around 32 hz. And I not sure wat would sound best wit the speaker direction and port direction so any advice is wonderful.

Hey, I sent you guys a konaki motor about a month ago with an invoice of what I wanted. Just wondering what the statis of it ? The name is Jason Leonard if that helps. I left the invoice in a pouch outside of the box will my contact info, email address, payment options and what I wanted. If you could just reply to this on the statis of the motor/woofer. Here is the tracking number --> 1ZE4E0710335401132 Thanks -Jason

I ordered 1 18" Fi SSD. I plan on getting another one soon. And was wondering what kind of amp I should get? I went ahead an got the dual 2 ohm voice coils on the amp. I'm looking for something cheap. Possibly well under $200? Currently I have a MA audio 18" 1100 watt amp with a legacy audio 2000 watt amp and it hits hard but it doesn't have near the quality I'm looking for. With the new SSD I'm looking to run either a 1ohm or 2 ohm config. Not sure yet what to do. Any ideas? I'm also wanting to run the SSD at atleast 650wrms 800 would be perfect.

hello, If anyone can tell me the port length for a 15inch fully loaded BTL that would be great. they took down the specs for the new woofer i guess, making it unable for me to read it. So if anyone can tell me all the port information for a 15inch btl i would really appreciate it. Thank you

Ok so i dont have much room in my car (well is a van lol) i have like 17" form my very back seat to the back window. Is that enough room for 2 15"s? I can move the seat forward like 7-8 inches if not more then i would have to take out the middle seat i would do that if its nessacery. So i will take pictures soon and post them so you guys can help me out tell me what to do. Im kinda new at this stuff so be nice. Lol

hello i was just wondering if i could get an update on my sub...i sent it in last month and got a reply that it was in....and then replied back to fr...and haven't heard since thanks....josh

I'm probably going to order my Fi SSD 12in this Friday, and was wondering which coil to go with. It will be hooked up to a Kicker ZX750.1. And I read somewhere, that these can be somewhere between 900-950 watts RMS at 2 ohms. So would the Flatwind Coil be the best to go with.

i want to recone my 18 to a 10, any body know who i can contact for one or a price?

i just purshased 2 18" btls.i have 4 cf for each 8 cf gross for both.i want to tune the box to 36hz .can some one tell me how many square inches of port opening and the depth ofthe port that i need.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]

Currently have a 12" BTL (D2, loaded, daily) powered by 2500D. Box is 2.5cuft @ 32Hz (after displacement). External dimensions 27" x 18" x 16". Port is 14.5" x 2.5" x 40"? (forget, used subwoofertool.com few years back) Would like to get a bit more out of the lows. They hit good as it is now, even down to 25Hz, but they could probably be better. Just wondering what I would need to do to make another box that specializes in the bottom end more. Smaller box? Larger port?..etc. Was thinking, maybe 28-30Hz tune? Maximum dimensions: 31" x 18" x 16"

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

I have read from many 04/05 XXX users that the tinsel sometimes break. My friends 12" just broke last week and we're trying to get some tinsel wires and there so hard to find. Forum members have told me to talk to scott or nick at Fi car audio to get some. Seems they might be busy since i didn't get a reply. Hoping they see this and respond back. thanks

Hello, I currently have 2 15" q series dual 2 ohm with the b/p option .I'm running these subs in a sealed enclosure and would like to try them in a ported enclosure of 4 cft tuned to 30 hz .However, the FI Audio site doesn't tell you about port length only port area. I was hoping i might be able to receive some help here.
