Fi Technical

Robin (iamamp3pimp) was in the process of building me a 2.8^3 @ 35Hz box for my AA Chaos 15D2 when I had to sell the sub due to financial issues. My question is would a Fi BL15D2 run off my AP15001D work in this enclosure? Sub would have cooling, flatwind, and daily options. Looking to get decent lows and numbers out of this box, though sound is more important than numbers to me. Had the CHaos 15 in a similar box before with good results, just bumped up tuning on this new box from 30 to 35Hz trying to get a little better score than the 143.7 at 40Hz I got with the first box. Here is a pic of the first box, new box will be designed the same but built out of raw birch. Th…

My friend is buyin a Fi Q with all the extras and we were wandering if any body had any old box dimensions and i dont want the dimensions from the website Q 15 – We recommend using a sealed box in the neighborhood of 2-2.6 cubic feet of volume. Ported box we recommend using 2.8-4 cubic feet @ 28-33Hz. Again use 12-16 square inches of vent area per cubic foot of volume. so plz if u have some dimensions for an 15" Fi Q ported box Thanks

Well im running my 15 q ported right now and ilike the way it sounds but i was wondering how many of u are running them in a sealed box? I know the ported would most likely get deeper than the sealed but i was wondering hwo much of a difference it would be sealed and what other peoples opinions on the q sealed are. I do listen to alot of rap thats why i went with ported. Was wondering everyones opinions on the ported vs. sealed. thanks

i am looking to try out a new design in my ranger. this will be for a 15" btl fully loaded. my max outer dimensions are 50 long x 16 deep x 18t all. heres the kicker, i would like the sub in the middle of the box facing the roof and would like to have the ports doing the same on each side of the sub. i am looking to get it tuned to 30-35 hz. the only reason i want the sub in the middle is because my truck is bagged and i want the weight in the center for even psi on both sides. i live near milwaukee wi if anyone is wondering

Just a quick question, I have a JL 12W6V2 that I bought on ebay a couple of years ago. Sub worked fine for a while, but eventully died on me (my fault of course, got a lil greedy with the gains lol)and has been collecting dust at the house ever since. I was wondering if FI can do a recone on this sub? Thanks.

Hello all, I purchased a Q12 years ago and unfortunately for the life of me cannot remember if it is the dual 2 ohm or dual 1 ohm. There doesn't seem to be any markings on the sub or coils...how can I tell what I have? I could have sworn it was the dual 2, so I wired it in parallel to put a 1 ohm load on my amp. It sounds great, but the amp is going in protection mode when I turn it up. The amp is 1 ohm stable. So I pulled the sub out, wired it in series...which would put it at a 2 ohm load (if it was in fact a dual 1). No matter how much I turn it up, it stays on just fine. Problem fixed, right? Wrong. The sub sounds like crap now! As if the polarity is wrong or somethin…

ok here is my question can i run 2 amps (mtx tc4001) on a Fi q 12? the amps are rms 600x1 at 2 ohms. i know that the FI's are dual 2 ohm. right now i dont have the cash to buy the amp i want(sundown). the other mtx amp should be here soon but until then can i only run one VC? is that safe? any answers would be nice? my friend has one of the FI Q 12 in his 06 Z71 and man it sounds great... i want that sound

hey all i was taking some measure ments on my brother car(03neon) and i got the demensions of 36wide, 30 deep but only 16.7-17 inches high due to a seat belt thing...im looking for about 3.7-4 cubes, i know that i got more then enough but im wondering about the hight, im guessing 15 inch woofer pluss 2 pieces(top and bottom) of .75 mdf =16.5 inchs..that leaves .5 inches...you think that its enough high, and how do top firing subs sound and is there a difference, if there isnt enough hight i guess ill try that...thanks

What are the wiring options for the D1's? I can't find any charts indicating the wiring options for a D1 sub.

I was wondering is doesnt have a size recommended for the 15 ssd in a sealed box? Is there a reaosn for this? would they sound good in a sealed box? If anyone is running them in a sealed box how many cubic feet do u have them in? I cant run them in a ported box because the box would be to big to fit in my civic, any help would be appreciated, thanks

I was wondering if you guys had the specs on the btl 15" fully loaded. Specifically the displacement after the 3rd mag', mounting depth, and xmax. I ran a search but no luck. How do I calculate these specs if I want to double the front baffle board. what are they afterwards. thanks for the help in advance.

Having 3000 watts on tap, which can be made louder in a large ported box? 4 SSD18's or 2 of the more efficient BL/BTL's? TIA, Carl.

im picking up a 12'' bl and i read the best tuning for is 32hz, can i get some box designs to hand to the audio shop thats building the box? this is my first time going with ported and i know nothing about vent area and how many sq inches of port..so i could really use some help..90% of the music will be rap but id like it to be musical not just a fart canon or muddy, it will be a daily driver

i should be getting a 18 btl any day now so i built a box for it i have somewhere around 6 to 7 cubic feet not including the ports iam wondering how to get the box tuned at 32 to 35 hertz is it the cubic feet for which the box is made or is it from the amp and cd deck ?? any help would be usefull thanks yall

Has anyone on here made a box for any of the bl woofers on here from the box cut forum? I have never made a box before and found that cut sheet page and if it saves me $300 by not going to a car audio store to have one built I think I would give it a shot. Just looking for input on if they came out nice sound wise and all. Thanks for your time people's

so i was on my way to work and i was subbing as usual..when i got the scent of like something burning..i really dont have the slighest idea of what it is but i can only compare it to like plastic burning..i noticed it only smelled when the bass is hitting low notes..so i get to work..8 hrs later..im leaving work and start subbing again, it plays about 10 seconds of the song and the sub goes out! and this was about 1 hour ago..so im pissed! i have no idea whats going on..everything is working fine except the sub..all lights indicate everything is good..do i need to recone it?? im not very knowledgeable with these audio systems! please help! this is my set up 1 18" fi btl 1…

i have two fully loaded 18 inch btls dual 1 ohm and one sundown 3500d for now not to sure on the way to wire them... preety much a noob when it comes to wiring subs....my guess is since that i bought dual 1 ohms i will only be able to run them at 2 ohms or .5 ohms if u guys could let me know if this is correct and maybe throw a picture up on how i should wire them that would be great thanks guys

Hi all, I just recently switched my Q10 from being sealed in an ext. cab S10 to .9cuft port enclosure in an '88 BMW 325ix. I took a ton of time designing the box for the bimmer because I was looking for more output down low so I shot for 27hz using 4in PVC. I got it all built up and installed and I'm slightly disappointed with it so far. Things just don't seem loud enough. I figured going ported AND in a larger cab compared to the S10 I would get more output but I'm getting significantly less. I must add, the enclosure is sealed up to the rear firewall firing into the cabin of the car through the ski pass hole so I have zero trunk rattle. I don't know how this would affec…

I am thinking about putting an FI Q 15 in a 2 cubic foot sealed box. I think that this size is on the bottom as far as recommended. Does anyone know how well the FI Q performs when it comes to small boxes like this?

Im getting ready to order the Fi 15 BL, i have a 1000/1 jl audio amp. Im not sure which is better dual 1 or dual 2 ohm? Is one better than the other, or does it not really matter?

so i have a d2 bl that will be on a saz1500 and was wondering on basic guidelines for a box. im looking for input from those who have played with em, or can tell me from other experiences whether or not 2.0 w/ around 40^2in of port would be okay. with the sub and amp in consideration should i go bigger/smaller, more/less port?

I have a bmw 328xi sedan and im gonna be running a single 12" fi q in a sealed enclosure because i wanted more sq the sub has the high qts option and the heat ring the website says .8-1.5 cu. ft what im wondering is what would be optimum size for the best sq for a wide range of music.

Hello, I am new to this forum and the proud owner of a new dual 2 ohm Q12 with BP option. I am looking to build a ported box for the sub tuned to the recommened 32hz. I would appreciate some help with the design. The sub will be powered by a Soundstream PCA1500D. I will most likely run the sub at 4 ohms for a while until I upgrade my Big 3 sometime this summer. I would like the box to be a slot port with rounded corners somewhere in the range of ~2 cubic feet. The box will be made out of 3/4" mdf Box outer size (max): 12.5" tall 30" or 32" wide (can't recall the correct measurement right now) Depth is variable So far my calculations have brought me to the following: …
