Fi Technical

Hey everybody i was wondering if I will get a better spl level if i face my sub towards the front instead of the sub facing the rear of the trunk.... My enclosure is 3.0 cf3 tuned @ 35 hz... Fi BL 15.... the car is a 05 kia spectra lx

How do these plans look for a BL 12"? Flickr Photo Download: Screenshot-01 Jan. 02 Thanks for your help.

HI. How many costs RECON to BTL + shipment? How long are they waiting for RECON? How to order RECONKIT quickly from the FIcaraudio company? I sent 3 messages Email to the [email protected] address and silence. Nobody is answering please help my BTLs 18" ; Ohm: dual 2 P_Chamfer: no Cooling: yes HiXmCoil: yes Daily_or_SPL: Daily Induct_Heat_Ring: yes Universal: yes

Hello everyone, I am trying to decide if I should just get an amp that will do full power at 2 ohms or order a D1 BL 10 and a recone for my BL 10 with the universal option. My current amp is 1 ohm stable, it "Can" run at .5 but only if my electrical system can support it, which it cant because its all stock. So, on to the real question, if I just order another BL 10 D2 and run my eD 9.1 at 2 ohms for 900 to 1000 watts rms, will my BL's still sound decent with only 500 watts rms. I know underpowering will not hurt a sub unless you clip, I know the recommended rms for the BL is 1000 rms, I know I should have considered all of this BEFORE I ordered my BL in D2. But I had pla…

I am running (2) of the 12SSD's in a ported box at right about 4 cu. ft. net and its tuned to about 32 hz. power is rated Zapco 1000W if I can get another cu. ft. What can i expect in the characteristic of the box? More efficent? more boomy? I do not want to make it sloppy, it's already ported which is a trade off for me to begin with. Or I might consider the max sized sealed box. How would you compair that to my existing ported box? thanks

I have a 2004 F150 super crew. I dont want a blow through and I am thinking about taking out the middle rear seat and putting a center consoled 15" there. I currently have 2 10" Qs under the back seat but I wanna go louder so I need someone to help me design something width needs to be 17" - 17 1/2". and height there is plenty of room id like to keep it under 30" and there is enough depth for 30". Iv been messing around on the rockford boxwizard and im looking at possibly a wedge type design with a flat on the back top of the box with aero ports and then the front facing sub.

Well i'm not sure if this is the right place to post this, but i'm wondering what options would be enough to get a 15" BTL at around 2600rms with ease? Thanks

i need help with measurements for a enclosure build for two fi bl 12 tuned to 32 hz. i can build this enclosure up to 4ft wide 18in deep 18in tall im looking for this to be a 5 cb ft volume... thanks for your help i need all measurements and slot port width lenght measurements... again thanks...

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 ?

first system about 90% finish, would i need a dual 1 or 2 in this situation, dont wanna go 1 ohm strapped at all since they dont make HO alts for a 2002 deville yet, still looking... got a chamber t line built by rich that i,ve had for about a year now, 2 1500ds, 100.4 coming temp. highs i have arc audio fd6000 up front and kenwood excelon coaxils out back on a aura rpm4200 4 chan. clarion max675vd II for the headunit and a clarion equalizer. kicker kyperflex, kollosus 4 guage 4 chan on the way. no alt but i was told that the alts in the 02 devilles and dts really put out about 180-190 amps as told by ohio gen after they tested a few, also adding a powermaster also. thi…

I've been searching google for a long time now, trying to find the actual formula. I have always used an online calculator when building my boxes, and ended up just building where I thought looked good. I was using this calculator here: http://www.carstereo.com/help/Articles.cfm?id=31 because I am wanting to build a new enclosure for my yukon, but I keep getting different figures depending on if the width of the port is larger, or the height. I want to build a box with 20ft after displacement so each btl will have its minimum 5ft. I was going to see how long I needed to make the slot port if I just stretched it across the bottom of the box. The box external dimensions are…

Hey guys, I'm looking to build my own vented enclosure (my first) for a 12" BTL fully loaded. I have looked at the box builder programs, but am having trouble. Would someone please design on for me? The maximum dimensions are 15"H x 34"L x 30"D. I plan on making it double baffle, and adding a magnet holder. But I guess before finalizing a design, I was thinking that it should be tuned to 35Hz, what do you guys think? Thanks for the help in advance, Justin

I found these specs ~4 cuft net tuned to 32 Hz 16" h x 40" w x 20" d Port is 14.5" x 4", 30" long. To get 30", you make the side port wall so it extends into the box until it is 4" from the back wall, then add a piece 10" long running parallel to the back wall. Box is .75" thick, except the baffle is 1.5" thick. I made this in sketch up to specs I wanted to see if it looked right. besides the port being off the ground i think it is. I am new to building sub woofer boxes so any help is appreciated

like it says want to build another box for my btl if someone could help with some tuneing and a 3rd dimention it would help thanks. Oh it would be a 1/2 wall can go 36X20X?(maybe 24 to 30 inches) external and would like to tune to 36hz feel free to PM me or answer here also there will be 6 in internal radius corners on the backside and matereal would be 1.25 in thick. Thanks for any help MC

I tried to get the most port area possible using an "L" slot-port. The box is 39"x18"x18". I wasn't paying attention to this when I designed (threw together) the box. Fi recommends 12-16 square inches of port for every cubic foot of interior volume. 48-64 I have 74.25 square inches of port and 44" length giving me a tuning freq of 31hz. And here's my question, should I (could I) do something (short of taking the box apart) to reduce port area, and raise tuning? Specifically, can I cut another 3/4MDF piece to fit snuggly in the port to bring the width from 5.4 to 3.75...or similar?

I was originally talking to Scott about a Q 18 in my h/t setup, but I have a chance to get a used SSD 15 instead. It needs reconed, so I was just wondering about the best coil for the recone, and a few questions. I was planning on asking for the copper coils with the recone, but I was just wondering if it would be best with my setup. I was goin to use one of the following plate amps with it, so around 500rms at 4 ohms. Bash 500 http://www.partsexpress.com/pe/showdetl.cf...tnumber=300-752 Dayton 500 http://www.partsexpress.com/pe/showdetl.cf...tnumber=300-806 At the moment I'm leaning more towards the Dayton, but I wasn't sure if it was worth the price difference. Also cou…

In my van. I'm running a rockford fosgate p8002 with zero guage wiring to my 18" dual 2 ohm p chamfer BL at 4 ohms about 800 rms. I was wondering what i should have my amp at for gain and frequency i got about a 6 cubic foot box not really tuned. all i listen too his rap. I just want it too be super loud. i'm borrowing the box from a friend while i'm building mine. thanks alot

Hello there! So a couple months ago I reconed my 12'' fully loaded (older-model) BTL. Before, it lived in one of Pete's Team Toxic Enclosures...but due to the possibility that it may have blown because of the complexity of the enclosure...I want to design a more simple one with the same dimensions of the previous. Problem is, I do not know how to design one. The dimensions would be 20 by 30 by 14. I would like it to be tuned at 32 hz. If someone could please point me towards a thread with the same specs, or design one for me. I would be very greatful. The sooner I could have this figured out, the sooner I can build the box and install the subwoofer. Thank you. P.S. : …

I saw NDMStang65s post and how he hit pretty good numbers with a single 18" BTL and a hifonics bxi2008d. I'm getting a set-up like this and I was hoping ( talking mostly to NDMStang65) If you could hook me up with a good box design to let the BTL get loud Thanks! Cody

Okay, so i messed up a little. I have a hifonics bxi2601d amp, and i wanted to wire my sub to 1ohm. I ordered a 12" fi BTL fully loaded dual 1ohm model... OOPS! anyways, i tried to change the order, we'll see how that works. If i am stuck with the 1ohm model, and i wire my sub to 2ohms, meaning it will get the rated 1700w rms, (probabaly 1200-1500 actually) do you think it'll sound under powered? I'm running 0/1 gauge wires, and my box is 2.73^3. Stock alt and battery for now. My goal is to sound better than a jl 13w7, my buddy said hes hitting 143db on the reader. you think Ill get him?

Im running a T20001bd to each fully loaded BTL.. how much output would I lose if i ran each sub in 3.5 NET compared to 5 net.? Tuned to about 32hz..

Well my computer crashed and I lost the t/s specs I had saved into win isd for my older model 15 inch Fi Q dual 2. I am throwing around new enclosure ideas but the specs for the new Fi Q's seem a bit different. When I use the specs for the 2010 Q it suggest a ported enclosure where as the older one always suggested sealed. I am sure the specs are reasonably close but just the same I would like to get the t/s specs for the older fi q 15" d2 model if at all possible. If anybody could help me out it would be greatly appreciated.

I'm the one with the konaki motor ! Please recone it. I've sent you guys emails and nothing yet. Its been almost a month. Give me dual 1 18" with the strongest softparts available . K-thanks bye. My email is [email protected]

Guys, I was wondering why some people go outside the recommended cubic feet from FI for enclosure size? I am thinking because its vehicle specific or is there another reason? I have seen guys running 4 BL 12's in a 13 cube net enclosure.

I didn't think that I'd do this but. Heh, it happens. I'm a complete boxbuilding noob. I know how many cuft Fi recommends and how much port area they recommend. But, I've tried my hand at it and failed. But anyways, Here are my max specs. 49 inches wide 27 inches deep 16(I may be able to squeeze 16.5 out of it) inches tall I'd like to do the port either on the left or in the middle. But, since I have seen/read/heard loading problems I'm pretty unsure as to what to do. I may be concerned about being loud but i would much rather have my woofers happy and lasting longer. I love reading posts about box tuning and loading. Since that is probably the only area of car audio that…
