Fi Technical

I wanted to know if the RE SX recones that fi have on the site will fit and work in the HC motor as well. I tried to get a hold of Nick at FI through several emails to find out but no reply , so after a couple of weeks I went ahead an ordered the RE SX 15 d2 as there was no recones for the HC on the site . any help would be appreciated Thanks in advance.

Will this enclosure work for two 15" btls

I was wondering if someone could list the parameters on the 2nd gen (UFO style magnet) BTL's for the 18". Im playing around with some Win Isd plots and was wondering how my BTL would compare! Thanks for your time!

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

I have a toyota ex cab truck and I was wanting to know what is the biggest sub set up I can fit in the back? The space in the back is 19'' deep X 22'' tall X and 53'' wide. I want to do a ported box with either 2 Q18's or 2 Q15's. Given this amount of space what do you think I could fit back there? -Alex

I believe I will be running this amp at 1ohm to my dual 2 ohm sub. Will this sub handle what is said to be 1500w RMS from the SAZ (which I have heard is under rated)? I am not planning to pin the gain or anything, I just do not want to blow the sub.

I already have 1 BL 12 with a sundown 1500d on it now, i was going to sale it and just get some 18s or whatever. Now if I go ahead and just get another BL 12 with same options I have now which are D2, cooling, and flatwind, and run them to a pair of strapped 1500d's they should be fine with that power? I figured they would be ok, since already have 1500 watts on 1. thanks.

I have a 2003 Chevrolet Tahoe and I am going to put a Fi BL 18" in it. It will be powered with a Rockford Fosgate T10001bd amp and a Kinetik battery. Just ordered it yesterday I have a general idea of the specs on my box in order to fit the 5-10 cubic feet. It will be about 9 cubes by the time everything is displaced. The only problem since I am new to car audio and this is my first system is what are the dimensions of the port? The box will be W 45" x H 20" x D 20" with 3/4" MDF. I want to tune the box to 32Hz. Any help will be appreciated. -Kasey

i would greatly appreciate it if someone can tell me where i can get a book/manual on how to build enclosures all types

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

Hey Guys, Could anyone help me with a box design, I built some sealed ones, but I just am not sure how to calculate the ports and tuning with ported ones. Even with the Box calculator's. I am looking for a box to hold 2 15 BL's and a box for 1 15 BL. Tuned from 28-32 Hz, Not sure on what would sound better. 30"depth 42"width 20" heigth these are the specs I wanna work with, I can fit more but, this is really what I wanna stay around Anyway, Thankx to anyone that can help me with this. Josh

could someone give me advice on a box for 2 BTL's 12?? it'll be powered by a 3500D or 2 2000D's. thanks

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

Hey, I have 2 tc 3hp motors. I know they need to be sent in to be machined to fit the 12 spoke mounting holes. I saw where you posted prices for a 3hp recone, there were prices for a 12/15/18. Can you do a 3hp 10" recone?? The motor measures 7.5 inches wide at the widest point. I'm hoping there won't be a problem with 10's. I'd like to send them this week, but waiting to see what can be done. Thanks FI.

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

scott, i sent you an email earlier today on a sub project im doing. wanted to so if you were up to it. thanks bud! Damon

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

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

Hello, I'm new to the forum and would like to say to the Fi section I've done a lot reading here and searching but never really found the answer I'm looking for. I already have a Kicker sx900.2 and looking to get a single 12" SSD. From the research I found so far I've came to the conclusion that getting a SSD 12" with the copper coil option would be my best bet for the kicker? The amp would run bridged, 850 watts @ 4 ohms so would the kicker be a good match for the ssd? If not any help would be appreciated. Just trying to get some feedback before I make my purchase. This will be my first time buying a Fi sub or even listening to one for that matter. I can't wait! thanks…

Okay so the Fi Q15 recommends a Ported box: 2.8-4 cuft @ 28-33Hz.... Using the Measurements below will i successfully build a box 4FT^3 tuned to 33Hz ? Or is the Websire giving me False Info ? Website used is Subwoofer Enclosure Calculators, Fraction to Decimal, Parallel, Series, Port Length and Volume Calculators

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?

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'm building a 2.5 cu. ft.box for a BL 12 right now and I'm aware of the recommended port area but I was wondering what the downside to more area(42 inches) would be. Thanks.

alright so i decided i'm going to build my box sometime this week. i'm having a hard time using box calculators and i don't quite trust my results for some reason. the box is going to get crammed into my 98 corolla. i made a replica box out of cardboard and the box has to be 17" heigh, 20" deep and as wide as needed. the sub is a fully loaded bl 15 and i would like the box to be 4cubic feet tuned at 30hz. can anyone please help me? -phil

Hey, I'm looking to build a new box strictly for street beating. I'm looking to tune it down to 30 hz. It's going in a Mazda 6 so I don't have excessive room to work with... External dimensions of the box will be 40" wide 27" deep and 17" high (double layer on top). Sub will be facing up as well as the port. I was thinking of putting the sub in the middle of the box, closer to the back of the car, and the port closer to the front of the car facing up. What would be better for music? 3", 4", 5" or 6" port width? Any ideas guys?
