Fi Technical

hey guys, i would like to know what you think of this box, im a some what noob/mid level at box building SUB- ssd12 basic with maybe a flatwire option AMP- rocksford t500.1bdcd, the birthsheet on this amp say it does 810watts at 1 ohm, which is what i will be running it at. here is the box http://s1244.photobucket.com/albums/gg580/ott9311/?action=view&current=a1_zpsf9dcb1d5.jpg please give me any input u would have, i listen to alot of rap/hip hop so im tuning for 33hz i know im prob under powering the sub, but i thought in a ported box you could under power it by a LITTLE bit. based on my above state facts, should i make the box any smaller or bigger? more or less po…

im looking at using the ib3, and was wondering if there are any technicalities that i would need to take into consideration before doing it in my car. i would place the baffle behind my rear seat, and seal everything off w/ fiberglass where it goes under the rear deck and between the wheel wells/strut towers. anything else to take into consideration?

whats the most power you could safely put through a btl 18 loaded, and not blow the coil? im just wondering what some have tried and found to work where as someone might have tried ____ and blown said sub.

First off. I am Unimpressed with FI's Silence. Unfortunately Scott and Nick have pretty much decided they are going to Ignore my Emails concerning taking them (Scott) up on the offer to replace the sub of find a magnet cover to hide the huge chunk missing out of the Ferrite. 2 weeks worth or emails have never been replied to so I have decided to cut my Losses and install the Subwoofer in the Oak Ply box I built. I waited and waited but with the weather turning cooler I wanted to get it in and running. On a Side note, a few Woofer builders have offered to repair the woofer at a reduced cost to help me out. So that was nice of them. I may take one of them up …

I'm building a 2.5 cu. ft.box for a BL 12 right now and I'm aware of the recommended port area but I was wondering what the downside to more area(42 inches) would be. Thanks.

Hey everyone Just a really simple question. The enclosure measurements for Fi speakers, are they measured before woofer displacement? Just need to clarify so I can build an optimal box with maximum air space.Thanks again!

i have a 15' Q. want a box that will get really loud. recamended size is 2.6- 4 cu ft. @ 28-33Hz. with 12- 16 sq. in. of port per cu ft. would a larger port be better than a smaller one?? i was thinking of doing 4 cu ft. @ 35 Hz. with a 6" x 10.5" port. how long would i need to make the port to tune at 35Hz??

I've gone through almost 20 pages of this forum and still not sure exactly how I should build a box. I've got a general idea, done some research, but I'm hearing/reading different things. I plan on purchasing a fully loaded 18" BTL very soon, but want to get the box out of the way first. My max dimensions I'm working with are, 39" Wide, 20" height, and 24" depth. I want it to be sub up, port back. This is going in the rear of a Nissan Pathfinder. I'm also wanting to get it tuned to around 32-33hz, that's where I'm having trouble. After sub displacement, and a port tuned to that frequency, how much cubic feet would the box be if it was built to those max specs? Just from a…

hey guys i posted a few months ago about half of my port being covered up and basically it isnt much louder and it makes the music sound sloppy so i dont use it i was wondering if anyone could give me tips on a new box that i could build for it to get some more out of the sub box specs: 35" Wide 16 3/4" Deep 27" Long port specs: 25" Long 5 1/4" Wide 16" deep (outwards) 11 3/4" deep (inwards) (port isnt typical L shape) http://s1284.beta.photobucket.com/user/FiAudioUser/media/boxspecs.png.html?sort=3&o=1 (pictures) i drive a station wagon and have a few more inches long/wide to expand if that gives me some more DBs any help guys? ask any questions you…

do u guys have a list or catalogue? I hate asking for each individual part... I feel like im always hastling uguys here for recone parts either way need some dvc 1.4 and 0.7 alum coils, cones, spiders, tinsel(the thick stuff) and some dust caps do u prefer an email with a list?

What is the best option setup on a BTL for SPL use only and how much power will they take for Burps only?

Hey Guys, Could anyone help me with a box design, I built some sealed ones, but I just am not sure how to calculate the ports and tuning with ported ones. Even with the Box calculator's. I am looking for a box to hold 2 15 BL's and a box for 1 15 BL. Tuned from 28-32 Hz, Not sure on what would sound better. 30"depth 42"width 20" heigth these are the specs I wanna work with, I can fit more but, this is really what I wanna stay around Anyway, Thankx to anyone that can help me with this. Josh

This is my current box plans for the 1 18"BTL and 1 Saz-3000d I have. I plan on putting all these into a 03 Tiburon(hatch) and competing in spl. Really my only question is would a bigger box better/ is 5.27 cubic feet enough. Thanks box: (outer dimensions) heighth = 16.5 width = 36 depth = 21.5 port: (inner dimensions) heighth = 5 width = 7 length = 10 this port will tune the box to about 34.67 hz which is what i personally like to tune mine to. after port displacement...this will give you about 5.27 cubes of air. so you have room to brace it and not go below the recommended volume. this is also assuming that you're using 3/4 MDF. competition port: (inner dimensions) he…

im planning on making my own box for my btl. but im not really sure on the port at all. so here is my question im planning on making a box with about 4.5 ft3 of air 35.25L x 18W x 17H how big should i make the port if i want to tune it to 32hz? like the outside length and width, and the internal length of the port thanks if you have any suggestions ill gladly take them this might of been posted before but the search hasn't worked for a couple days now

Does the sub come with aluminum or copper coils? sorry if theres a thread about this but i looked on the site and couldnt find a difinitive answer on this. Also what exactly does the BP power option do, does it effect the sound of the sub whatsoever or is it something just to help with thermal capabilities of the driver? thanks in advance.

I sent my sub off about a week ago to yall to have it reconed i was just checking the were abouts on it. . . i sent it to the address on the fi website. . . just tell me if yall have received it yet.? Thanks, Charles

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.

Hey, I sent you guys a konaki motor about a month ago with an invoice of what I wanted. Just wondering what the statis of it ? The name is Jason Leonard if that helps. I left the invoice in a pouch outside of the box will my contact info, email address, payment options and what I wanted. If you could just reply to this on the statis of the motor/woofer. Here is the tracking number --> 1ZE4E0710335401132 Thanks -Jason

Hi, i have a blown tensil lead on my X 12 and i was wondering if Fi could re cone it or replaced the bad lead. This isnt my first blown lead. Before i replaced them but in removing the dust cap i cut through my cone, so i'd rather send it off to Fi. Does Fi cut off the dust caps for this kind of work? or just recone the sub? If a re cone is needed to repair the sub, is there a recone available???? Thanks!!!

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 ?

How much do they take up as a far as displacement goes..

my glue is coming loose from the surround to the basket what can i use to reglue

hey guys need to know what kind of amp should i get for my fi btl 12 fully loaded at dual2... whats the max i can go with rms for this bad boy..its 2krms on the home page but it says that for every btl...can someone please help me...please

* Rated RMS Power = 200 watts * Mounting Depth = 4.25" * Outside Dia. w/gasket = 8 5/16" .........(inside the lip is 8 1/8") * Inside Dia. 7.000" * Sealed Box: 0.280 ft^3 w/ F3 of 50 Hz (Qtc = 0.707) * Ported Box: 0.60 ft^3 tuned to 30 Hz F3 of 25 Hz * MSRP - $99 T/S S4 **: RMS: 200 Re = 3.37 ohms (4 ohm nominal) Fs = 34.9 hz Qes = 0.5323 Qms = 6.93 Qts = 0.4943 Vas = 7.6 L BL = 13.3 N/A Mms = 127.7 grams Cms = 162 um/N Xmax = 12mm one-way linear (70% BL method) I made an album with measurements of anything I could think of that you may need to know in order to find/build a recone kit for these... I'll need maybe 12-14 of these. thankyou!~!!…

I'm trying to figure out the port diameter and length for a box I'm going to build, but every time I use a formula from the internet I get something that doesn't seem reasonable. The box is for a Fi SSD 15. I figured the dimensions are 25x15.5x17 which is 3.81 ft cubed. I'd like the port tuned to 33hz. If anyone could help me out it would be greatly appreciated. And if you could leave the formula for future reference that would also be appreciated....thanks
