Fi Technical

Hi, idk if someone's read it in my build log but im looking for someone ho can create some blueprints for a dbdrag enclosure.. I'm also ready to pay a little tip for it so like said: Anyone out therer for help? I can give the max dimentionts if someone can do it.. faezich

Mainly for the bigger heavier 18 inchers but not excluding other sizes.I'm curious to see what you use.Bolts,screws,clamps etc.Do you switch from screws to bolts at certain weights and so on.

Rather then stay up until 3 in the morning for firechat due to time differences i though id ask here... Need a sub for my HT. Currently I have two BL's in my car. I want something that that plays lower with more depth then the BL's. I love low lows with presence. IB is not a option in my current place. What is my options and what options should I select? is there something else I should specify? Sealed ported whatever I can build the box and consider my self a bass-head intermediate but this whole HT thing has me baffled. I know Scott has his finger in other sub companies as well, which makes me think why Fi and not any of the other companies he has a part in? I ne…

What are some optimal dimensions for a box for a Fi BL 15. I really want "SQL". Need to know how many drivers port area port length tuning frequency. (W x H x D) Thanks for the help.

Like the title says, i was wondering whether the terminals on the FI subs can fit 8g wire or if ill need to go with 12

has been fixed. thanks

I currenty have thhe two subs in a 4th order blowthrough off of a 4500d on 16 volts. Gains were set around 1/2 way and it pounded for bout 4 days. Then I decided to turn it up a little. Between 1/2 and 3/4. Now the subs don't seem near as loud to me..could it be I'm just gettinng used to them? I'm gonna check with the dmm tomorrow and read the coils and see how many watts the amp is putting out...I hope I didn't mess anything up:(

ok, well i have truely made up my mind and will be going with the Fi Q 12". my question is, will this box be good for the sub i.e. enough room for the sub to "breathe"? Box specs: Depth: 11 Width: 30 Height: 16 CuFT: 2.27

Ok so i have had my Fi BTL for a cppl months now and i was bumping it today and the Dustcap flew off. Does my warranty cover repairs on that? if so how do i go about getting it fixed?

just got my bl in and i was just wondering if there were anyway you could tell if they built it with cooling, hyperpole etc. thanks

Since I've bought the sub,I noticed they sell a fully loaded BTL.My sub only has 2 magnets.Is my sub the 2000w rms model,and what year sub do I have.my ride

I got a 93 740il, i want to mount the subs on the rear deck and do a blow threw... dimensions of the trunk are - width 3', height 1.5', and there is a difference of 6.5" from top depth to bottom depth being the top is less, the port thru the rear seat can be a max height of 1.5' and is set at 1.1' without cutting any leather seat and width of 10", i have allot of room to play with the depth in the trunk well over 3' in the least deep spot, i tried using re's box calculator but it didn't help that much. thanks.

Alright guys, so i have a dual 1 ohm q18, and i need an enclosure, the specs on the website aren't specific enough, i want to know what size sealed enclosure, would be best for sound quality? I am getting my enclosure professionally done by my local car audio place, and he needs the specs that i want it at. also how do you wire the 1 ohm subwoofer, i'm new to this-lol so please get back to me on this asap. thanks -aj

I have been building my brothers blazer for stereo competition. I have the build in the build log area under "walling an s-10 blazer". The system is Four MA Audio 802sx amps (about 2500 watts RMS) to four 15inch fully loaded BLs with the SPL option and they are dual one ohm. The amps are then running at 1/2 ohm mono. They are in a 23 cubic foot box with a port mouth of 32 x 9 inches and it is 2 1/4 inches deep. Our best test score today was a 153.7 at 51 hz. We tried longer ports but the one we started with is the loudest so far. We have not tried making the port mouth smaller and it can not be any bigger. We also have not tried putting stuff in the box to take up…

i have had my fi q installed in my car for a few weeks. today i was listening to it pretty loud, but nothing too crazy when all the sudden it stopped. my power light on my amp is still lit up (jl1000.1), all wires are connected. any advice or thoughts on what happened?

so i hear ia is coming out with a 21" subwoofer. should i expect fi to come out with just as big or bigger in the near future? Damon

I am in the process of building a box and am thinking of using polyfill. I just wanted to know if polyfill works the same with ported enclosures or is it purely for sealed boxes only?

hey guys heres the deal, i finally got my ported box completed and installed the D2 15" BL, hooked up the amp (aq1200d) to 1 ohm, saw that my fuse is blown so i had to use my friends to see if everything was working.. the amp was showing power, and hooked up a capacitor just to see and it was getting the proper volts, but NO response from the sub, no movement at all. We were soo confussed, everything looked properly installed. just wondering if anyone has any ideas! Please help, i appreciate any given. I miss the bass also how do i properly tune my amp, and where do i put the knob angled at on the subsonic, i need it set about 30 hz which is 2 under the box tuning, but t…

So... I was on my way home listening to my Q and it suddenly stopped working. I parked and left it on and felt the sub while it was playing. When I pushed in just a tad, I felt it move a little. But when I let off...nothing. I took the sub out and found that the black plastic piece that holds the push terminals in came un glued. Im assuming that's the problem... I tried to get a reading with my DMM, but I think its a piece of junk. It just read 1. My gain is at about half. Amp is a planet audio rxd1000d which im selling soon. 2.5ft^3 box at 32hz. Don't think all that matters though considering I just need to know how to fix it right? Anyways...thanks in advance. Jonathan.…

Ok guys i wanna get 2 Q series 12" subs my only problem is i dont what dimensions to use for a ported box and lso a sealed box. If any of you know please share im trying to either et cut out sheets for them or get the dimesions needed thank you. I was told to ask JBLCamry but i cant find him thanks ahead of time.

i need help finding some screws that wont brake when the bass hits from my btl im getting tiered of putting new ones in what are some good screws thatll keep these beast down

Hey guys Im going to build a new box for my 18" Q. I have 6.7cu. ft. before disp. and port.. which I know is small, which is why I need to use aero's. Right now I have 4x 4"x10" aero ports. can someone give me recommendations. Do I need to get 6" ports?? I know for port area that 2 of these 4" aero's isnt enough, but I think if I go to 3, mine are to short... Can I use the flares, and use PVC pipe to make them longer??

Hi, I have a Fi BL 15 of 1000 Watt rms 2+2 ohm. I'd like to create a ported box too much little as possible. I'd like to place the box in my car as in the picture. Can I have a project please? Thanks a lot

Ok well i built a box for an 18" Fi BL the specs are 42" wide, 22" high, and 22" deep. The port is 5 inches wide and 15.5 inches long. tuning it in the upper 31hz range. The box was like 8.3 cu ft. before woofer displacement. is that too big for a 18" BL with flatwind coil? Because the box doesn't sound good at all. and the woofer gets pretty warm on zx1000.1. I feel like its too big but i could be wrong.

I am running a fullyloaded bl15 off a planet audio bb2400 making about 1600rms. Electrical- big three, 1/0 throughout, second battery in rear, voltage stays around 14.3, drops to 13.6 for tones. My first enclosure was 5ft^3 tuned 36, 60 sq" port, with bracing, angle boards and routered port edges. Sub faces drivers seat while port fires up behind passenger seat. I hit a 143.8 meca style. Built a new box 3.5 ft^3 tuned 45 with all the bracing, angle boards and routered port edges and dropped to 141.7. I wanted to find out what box changes I may make to increase score, and if I was crazy trying to reach a 150 with a bl?
