Fi Technical

Need help with deciding on building enclosure for (2) 15" FI BTL. Going for ~36hz This is the amount of room i would like to use: Width = 36" (Max width due to wheel.) Height = 24" Depth = 22" Would be sound better if the sub face up or sub face back. Also the same question apply to the port. All of this is going inside a SUV. What are your recommendation for the port? If the above measurement are small, please give me some recommendation. I would like to keep the box small but also sound good.

My enclosure is built at 2.5 cuft, my current port area is 10x4x21, tuned to 39 hz, I want to change this so its tuned to 32 and I would need to add 14 in in length, unfortunatly not possible. So I looked into it and I could change my port to 10x3x25, what will I lose(or gain) by changing the port area ?

Im just hopin that someone can help me out with gettin the info to order a FI Sub i have a alpine type x and it aint the bass im looking for and ive been watching steve meade and its just WOW!!! and a guy came by my school (Mobile Technical Training) with two 12's and it made the whole car shake i even have a video of it but yea i live in the Virgin Islands and i would like to know how much would it cost and if its possible for me to get it cause i really want one, thanks to anyone who can help me with this.

How do these dimensions look for my Fi Q12 d1 Box outside diameter after using 3/4" MDF: Box: 33.5 x 14.5 x 12 Port: 1.5 x 13 x 16.5 This should give me 2.53 ft3 (before taking away sub/port displacement) and be tuned to ~32 Hz. I have been using website like the12volt.com and a couple others. I tried the RE enclosure app, but I think it is a little off. Not too sure. I appreciate any help! If this box looks off, what would be better? Thanks.

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

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...

Not at the same time! I have two boxes built for my single 12BL. (D2, loaded, daily) One is 2.5cuft @ 32. Slot port. Homemade The other is 2.0cuft @ 32. Kerfed port. PTS They are both designed around the 12BL t/a parameters. Two questions. Is the BTL a substantial upgrade from the BL? Could I use the 12BTL in the same box which was designed for the 12BL?

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 kind of started a post in the wrong area for BTL box questions. But I am looking at getting a 15" BTL sometime soon. I do have somewhat limited trunk space though (40x40x20). I would like maybe a little of extra room in the trunk for putting somethings (ie bags, books, backpacks, skating equipment etc). Can it be done to get the same boom / sound quality with a smaller box? I know on my other post, somebody said it was possible to make a little smaller box with biger ports to even the difference out. But how far can you take it? Like (I know you couldnt but...) making a box that only acted as a brace for the sub and maybe have some sort of diminishing cone around the s…

I want to build a SPL enclosure for a show coming up and wasnt quite sure about size and port. What I was going to build was... 42" x 15" x 10" with a port that was 10" x 4" x 21" Will this be good ?

Which way should I go? - Rockford T20001BD - Audioque 2200D - Sundown SAZ-2000D Will be powering a 15" BTL. Just need some comparisons. Thanks.

I ordered my btl a few days ago (fully loaded) and now it's time to buy an amp, what do you guys think of soundstream? The sub will be going in a 5 cuft pored box tuned to 32 hz Not trying to spend more than 500

I will soon be purchasing the Fi BL and was wondering if I will have to upgrade my electrical. The amp I will be using is either a sundown 1200d or audioque 1200d. Thanks

I recently bought a 15' Bl and had a enclosure in mind. The enclosures dimensions would fit inside my car, so I went ahead and bought the 15' Bl with the cooling option. It arrived a few days ago and I was super siked. Then I realized how would I get this box into my 99' Grand Am GT. The box will not fit. (This one http://www.bestbuy.com/site/olspage.jsp?sk...=1218009774927). Now I'm in a pickle. I have found another box that is ported,that i think will fit in my car. It is on the small side as far as cubic feet wise though. link to it --->http://www.bestbuy.com/site/olspage.jsp?skuId=9026797&st=15+in&lp=4&type=product&cp=1&id=1218009790168 Will th…

I have a box design in mind (i just need a car to see if it will fit or not) which has two either 15 or 18 inch (depending on available room) BTL's or BL's. I am not sure though if these subs are designed to be able to share a box together. I was originally going to run just a single BTL 18" in a 7 or 7.5 cu/ft box, but i wanted a more good looking design, so, as an example, are you able to run two BTL's in a box of volume 14-16 cu/ft? Or the equivalent volume of the BL's? I'll try to draw what i want it to look like on a CAD program or something, but i would like to know if it possible first before i start buying materials. Thanks

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?

Well I just had a box made for my 15" BTL and they kinda messed up...first they made the woofer hole facing up and the ports facing up also....do the ports facing away from cabin sound louder? Also i found out that the box is tuned to around 29hz....how will that sound?????? Will it sound good..will it be loud most also? I listen to mostly all rap just to let people know (i know rap sounds better in different boxes hz wise)...The box is around 4cuft also just to throw that out there. Help is much appreciated thank you. Here's some pics. Inside...one of the ports.

I had a box designed by chris at fishercustoms, and here is what he came up with: The total Net volume came out to be 1.8cu ft exactly, a 1.74" x 14" port tuned to 33hz, 13.53 sq in of port per cu ft, and I have a couple questions: 1. Is that too small for a 12" Fi Q? They do recommend a minimum of 1.8, but i'm worried this box won't make it sound good because the net volume is too small. 2. What happens if the box is too small? 3. Whats the difference between having a larger box versus a smaller box? Like having a 2.2 versus 1.8? Most of the videos I see online of this sub have a box larger than 2.2 cu ft, and their car is basically falling apart. Any help would be gr…

Hey guys, i am looking for a box design and was hoping one of ya could help me out. Its for 2 18" BL's powered off one rf t3000 going in a tahoe. I would like the dimensions no bigger than 28x48x22 if possible for daily driving tuned around 32hz subs up port back. I really dont trust myself designing one, but i guess thats one way to learn. Any help is appreciated.

So i was listening to my system today and i put my ear next to the box and i heard some sort of slapping noise. I know this cant be a good thing but who knows im a noob. I have a 12'' Q with the BP option being powered by a hifonics bxi1208d. I have the gain at half way and the sub sonic at 32 hz and the low pass at around 100 110. I have a down firing box, 2.5^3 ft tuned to 32 hz. Is the sub supposed to make this noise or what? thanks for any help

I am running 2 FI BL 18's in about 15.5 cubes after sub and port tuned to 32hz. It sounds awesome for daily and really picks up the lows. I have about 200 square inches of port also. I did 147.3 db on TL first time, then a 152.4 on an audiocontrol meter saturday. Now, I was told I should make my box around 10 cubes after sub and port and tune to 35 or 36hz and it would probably meter better and still pick up the lows. Does this sound right or do you have any suggestions? Oh yeah, I am running 2 sundown audio saz-1500d's strapped on them now. Would it matter with a slot port or are aero's better? thanks for any help

I recently just ordered me two 18" fi btl fully loaded and im selling my 18" q's to my buddy. What I need is a good box design for my btl's. My maximum measurements for the btl's box is 49"x20"x29". i currently have aero ports for my q's and im wanting to do a single chamber with a big slot port, subs up port back. And i also need a box design for my buddys setup, max measurements of 40"x26"x26", with the same idea as my box. so if there is anyone with ideas, let me know please. thanks

Does the recone kit come with the glue if not then what type do i need?

Alright so I am trying to build a box for a Fi Car audio Q 12" woofer. They recommend I build a box using 1.8-2.5 cubic feet @ 28-33Hz (32hz tuning is optimal, and has the most output and is still the most musical daily driving), and to use 12-16 square inches of vent area per cubic foot of volume. I am talking to Chris at fishercustoms, and he is helping me design a box. I was using the RE Enclosure Calculator, and I'm not sure what he uses. I gave him my max specs, 23" long x 15.5" wide x 16" high, and he came up with: 1.8 cu ft, 33 hz, 1.74" x 14" port ( 13.53 sq in vent area per cu ft) When i put those dimensions into the RE ported enclosure Calculator, i got: 2.068 c…

i have a budget of $500 for an amp can anybody tell me what would be better for a 18" bl and 18" btl i will appreciate any help from anybody. thanks, Jose
