In order to get a ported box just perfect could you just punch in your cubic feet what you are needing in your box, then get the port dimensions and figure up the displacement of this inside of your box and add in sub woofer displacement. After I add these up could I enter my Height, Top and Bottom depth, then using my length as my variable to figure up how many cubic feet I need? In other words say that I have a sub woofer that has a displacement of .11. Then i figure up a port that would displace .2 cubic feet in a box. I'm needing 1.2 cubic feet after sub and port displacement. So the box should be 1.31 cubic feet inside? Here are my two designs http://img.photobucket.…

I need to downsize my 18 to a 15 or 12. I have 3-3.5 ft box max that I want to build. What is the process to obtain the kit, and how do it install it? Thanks Jim

Ok so i have 2 12" Fi SSD Can someone Post a link on here or something of a recommended sealed or ported box? Please Help

Hey Nick or Scott ... need some help with an MT, I need a recone by the 4th for a local sound off (if I can get it next-day'd or 3 day guarantee UPS or whatever) but was wondering what options I'd have when it come down to the recone ... I'm throwing ~4k at the sub for burps, I want a dual .7 instead of the dual 1.4 it is now so I can run it at 1.4 or .35 for burps, but suspension/coil wise could it be upgraded? Also as far as the spiders are concerned upgrading to like 5 or 7 layer woven? I sent Nick an email yesterday or the day before ... just need this quick, so I hope it didn't find the spam filter

Like the title says, I was wondering if there are pumping losses or air noise exiting from the cooling channels or the like thanks. Just to be clear, I'm only curious about bp power option only, let's just say the sub was inverted for reference.

Right now i have my 18 bl in a ~6 ft^3 box (before port and sub disp.), tuned to 34 hz with a 3.75 x 20.5 in port (was supposed to be 4 inches, but i had a lil cutting error ). Anyways, i'd like to try a few different boxes, some higher, some lower, some smaller, some bigger. Fi has 30 hz as the lowest recomendation, and i'd like to see what the people who tuned to around this (or people who have heard a bl tuned to this) thought about it. They also have 37 hz as they're highest, so have any of you tuned to that, if so, how'd you like it? I realize a person who tunes to 30 hz is going a different path than someone tuning 37 hz, but i'd just like to see how each individu…

I sent you an email with my info, could you let me know if it went through. I didnt get the tracking info emailed to me yet so I just wanted to check if you got my email with the info. Thanks man

hey guys, im just using a temp ported box now that i made using the RE calculator. Its at 3.3 cubic feet for a 15" BL and according to the RE Calculator its set at 32.42 hz. I know its a little unnacurate but what would be safe to put my subsonic filter at. I currently have it set around 30hz ? thnx guys!

are ported boxes ok for rock music too? i have the room an would like the extra output from my ssd 12. but mostly listen to rock. could i tune it higher or lower an be good? or should i just go sealed. an be plenty loud enough with sundown 1000 at 1 ohm. any opiniones,help? appreciated

I am hoping that scott or nick can help me with this...i sent an e-mail and i know you guys are busy, but i have not gotten a response yet so i'll reort to the forum again... i need a dust cap...the outer one...i have my speaker reassembled and this is the last piece of the puzzle...i was wondering if i could buy one preferable a blank one....is this at all possible scott or nick? thanks for the time

Right now I have four JL Audio 10w3v2s in a 2.5 cf enclosure in my Suburban and I am looking to upgrade. My goal is good overall sound quality in my daily driver. Would you recommend 2 FI Q 12's or a single 15? I will be using one or two of my Tru Tech amps depending on which setup I go with. I am using Hybrid gear up front and would like to provide a good match. Thank you in advance for your time and help, John

sorry i dont know but what is the big 3?

I order a Q 12 from fi on the 17th of April. It been over 33 business day since I ordered my sub. Then FedEx sent me a shipment email saying that it would arrive on the 24th of April. I knew that was not correct. So I wait until June 12 before I emailed agin. No reply till last Thursday. When I got the email the said it said sub was being shipped and that FedEx would be sending me a tracking number? So I email them Friday asking about my tracking number and still no reply. I just want to know where my sub is.

How they compare head to head?

I was wondering what options I should do and what Ohm sub I should get. Each sub will be connected to a Kicker Kx2500.1 Thanks in advance,

Finally got back my 15" BL from Fi When i bought it from Joseph K., upon delivery, USPS dropped it and broke it. Soo, using the insurance money i reconed it to a 15" from a 10" Before After First impression= Damn that's huge! Thanks for everything FI, another satisfied customer.

EDIT: I just read about the shipping information thread thats pinned. Sorry for the waste of thread space :/ Thread closed.

what's up with the email system? sometimes i'll be going back and forth with scott, and suddenly i stop getting replies. I emailed June 1st, June 9th, June 11th, 14th. Still got nothing. It's happened a couple times already..

I know people say it takes about a month of (break in time) before the suspension loosens up so... currently i have about 1 hour of play time Is there a limited amount of power i should be feeding it before i give it the the 1,200 watts daily i planned to? ** Setup ** Sub: Fi 15 BL Enclosure: 3.8ft^3 @ 32hz (ported) Amp: Saz-1500

Whats up Everyone, Im new to this site, and hope to gain alot of knowledge from you all. I have a 2004 Escalde, and in trying to decide if i should go with 8 BTL 12s or 4 BTL 15s. I have two Soundstream 10000D amps, 8 kinetick 2400 batts, and a 2nd alternator for the additional batteries. I was running the solo x 18 but im ready to add more cone area and go for a different sound as well as move some serious air. Im not trying to build a wall tho. Ive been doing some reading and im hoping that these woofers will give me what i want. Any suggestions would be great appreciated..thanks in advance. G

My first sealed box for my 2 Q15's was 4.4ft^3. It sounded perfect. Now I have 4 Q15's sealed in 8.6ft^3 (after displacement). It is a little less then half the doulbed volume of the dual sub box. I assumed that my roll off would be nearly identical to my first box, or my tuning would be slightly higher, but it is actually opposite. It peaks at 35hz +/- but rolls off quickly above 40hz, as if the box is too big. Could it be possibe that the specs need to be adjusted do to box size or the amount of subs used? Maybe because it is all a single chamber? Because if this, I am considering doing a box that is about 10ft^3 with 4-5 4" round ports tuned to 34hz. That woul…

Can you guys at Fi build passive radiators that have stupid amounts of displacement on a 12 or 15" frame? I can get some 18's, but they're too tall for my purposes (I think). I don't have my new car yet, so I'm attempting to draw out something insanely different

I was thinking.... Right now I have a 15" BL with an RF T10001BD amp, its loud, very loud. I want a more sensible setup but attempt to keep the same sub output, I don't think its possible. I want small box, small amp, and still be able to do 140s. I know thats not possible. I just want to reclaim my trunk space back and my spare tire and jack!!! With that huge box in my tC there is no more trunk space!!!! Now I am getting kinda tired of hauling around a 100lbs box... Ok I'm done ranting....you may return to your regularly schedule program.

I had a RE HC rebuilt by Scott awhile back and when he did it, he did provide me with break in t/s parameters. If I provide the parameters could you give me a recone kit to match?
