Fi Technical

Anyone or ficaraudio, could sketch me a rough design for a single 15" Fi Q w/out bp power, d2 off a 1200watt @ 1ohm Vented enclosure Here is what i got to play with, for space *truck* 35" Width 20" Height 17" Depth Open to whatever tune, i want it to be low/loud but sounds good at the same time. Listen to rap/reggae mostly. Gonna use .75" MDF Thanks in advance! I wanna get started building my enclosure. Currently using reaudio box design software on their site...

Hey everyone. I'm in need of some plans for a ported enclosure for two 12" Fi SSDs (with copper coils if it matters). This will be my first box build...but I'm confident I can make a nice quality box. I'm just having some trouble coming up with some plans. Does anybody have some drawn up I can use for reference? Any help at all is greatly appreciated! Here's some info you all might need: I want the width to be 44 inches. It's going in the back of my FJ Cruiser and I am trying to build something like this: This picture shows what the actual box looks like: The width in the back is about 45 inches. So I think a 44 inch box would fit nicely like his. I'm mostly looking for…

Hello everyone well I just orded 4 Q15s dual 1 ohm and bp power the box im building will have 2 seperate chambers, with 2 subs per chamber, with about 5 cuft per chamber,is that enough space?this is a sealed box. Also i will be using 3/4 inch MDF board to build the box, I will be putting double layers on the baffles, should I double layer all the other sides of the box or should I just brace inside to the single layers? thank you .................Brian

I am running 2 FI BL 18's in about 15.5 cubes after sub and port tuned to 32hz. It sounds awesome for daily and really picks up the lows. I have about 200 square inches of port also. I did 147.3 db on TL first time, then a 152.4 on an audiocontrol meter saturday. Now, I was told I should make my box around 10 cubes after sub and port and tune to 35 or 36hz and it would probably meter better and still pick up the lows. Does this sound right or do you have any suggestions? Oh yeah, I am running 2 sundown audio saz-1500d's strapped on them now. Would it matter with a slot port or are aero's better? thanks for any help

Hey guys, im from maximum threshold, my team captain has been waiting for a reply from scott about recones for my MT that we need for db drag world finals. Is there any way one of you can speed up the process a bit or maybe we can talk to another one of ya about it? We are in dire need of the recones and our trip to finals depends on it. Its a dual 1.4 ohm recone for an MT. Scott will know what im talking about as he's been emailing back and forth with Peter for a while, but as of late the emails have stopped. Thanks for any help you guys can give us. Don Doyle Team Maximum Threshold

Well i built a sealed box with .6cubes net, its not the output i was expecting. I plan on going to a ported enclosure. its going in a 2008 frontier and there isnt enough room to have the sub and port up. the sub will be up and the port will be toward the passenger side. 1. port to the driver or passenger side? 2. i read the sticky and it said .5 - 1.2 cubes is it .5 min and 1.2 optimal or any where in between there will work? 3. should i do a longer narrower port or a shorter but wider one? sub 10" Q amp - hifonics 1208 (1200w @ 1ohm) (yeah right lol) if i get 1000watts out of it her happy max 15" high max 11" wide max 12" deep

OKay so i got my car back... 15" Q in a (supposed to be) 4 cu.ft. ported box.... i love it so far and sounds great. i need to listen to it more tommorw. i hardly had any time today. but anyways, to the point... My box is 4 cu. ft. which means the port should be 48-64 square inches.... well i have 4 3" ports which is: 1.5^2 x 3.1415 x 4 = 28.2735 if the box is 4 cu ft and i replace the 3" ported with 4" ports, that would give me about 50 (50.264) square inches but how much would it take from the rest of the box? how would it change the sound and output? and how hard would it be to change the ports out? I think it may be restricting the sub a lil with such lil port area...…

Whats a good port length for the BTL as a daily driver tuned around the recommended 32 hz and 14in^2 per cube? 2000rms power. Enclosure will be glassed into the side of my trunk and I have around 4600in^3 before any displacements to work with. So should be around 2cuft after. Trying to see if I can make a ported enclosure work or not. Thanks!

If anyone has tried this could you tell me what you think of it? I'm trying to build a wall that is all funky shaped. Trying to smash 4 18's into a Ford Explorer. found this program but would just like to know if anyone else has used and what you think of it. The bottom is 37" deep x 52" wide then go to 33" deep x 18.5 " high. Top is 33" deep x 52" wide 18.5" high Grand total of 37" tall x 52" wide and the depth. Trying to utilize every bit of room I can so I can still have room for batteries and amps. Plus the ports gotta go in there to. Any help on any other programs or any ideas would be appreciated. Got it drawn out on paper. Kinda to scale it down to where it will …

okay my box is 20"hight x 40"wide x 20 "depth according to the speaker box tunning calc. its is 7.63cubic ft. now iam trying to figure out my port on it and the lengths i have right now is 7"hirght x 9" wide x 15" depth and i get 33.81 hertz its the hertz i want my box to be tuneed to but the port area per foot is only 9.14"sqaured and Fi says the port should be 12-16"sqaured do i have to cahnge the port to be 12-16"sqaured thank you for your help

Curious specificaly on the ''Q'' 18 w/bp

outter box dimensions are gonna be 58" deep x 46" wide x 24" high using two layers of 3/4 mdf all around (1.5" sides) gives me 28.7 cu ft before displacement assuming displacement is .26 per woofer lets call it 1 cu ft my plan is to use six 6" aero's to start with i am aiming to get at least 25 cubes net after port and sub displacement (assuming 1.5 cubes displacement for 6 6" aeros 15" long) i NEED this box to be LOUDEST at 44hz, so i'm guessing tune to around 40hz (not sure) its gonna be only for bass race and shows, i wont be driving this setup around town everyday, but i still will be playing music, mostly rap and not much in the 30-40hz range. dimensions are pretty…

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

Ok. i am planning on getting 2 15'' Bl's. (Dual 1 ohm, cooling, and flatwind). How much power can i feed them without buring them up?

So I am trying to decide on which Fi.Q I want... Either the 10 or the 12. My plan is to build a custom sealed enclosure to sit in between the second row captains chairs in my Tahoe, and the sub will down fire. I am leaning more toward the 10 because of space constraints... the maximum size enclosure I can fit in there is 27" L X 14" W X 10" H... So would y'all recommend the 10 or 12 with that, and what cubic footage for the enclosure? Also, What amps would pair well with the Fi? I listen to some rap, but mainly mashups, EDM, and lots of rock/country (basically everything hahaha) Side question... I don't know if any of y'all have a Tahoe with the Bose upgraded sound…

which is better 2 or 4-ohm for a SINGLE BTL on a kicker 2500.1

Ok right now I have the Q 15's and I've gotten used to them so I want to upgrade to the BL series. My question is, ok i want the same freqency response as the Q's have cause I like how they perform down low, but I need to know which options in the BL should I go with to have a good daily woofer? I was thinking of going with the cooling, flatwind, daily, and universal options because I am not looking to do any competing just some really bad street beating. But Im a little skeptical about the cooling option because it says that there is less metal in the motor thus making it a little weaker? So should I just go with p/chamfer, flatwind, daily, and universal because I dont w…

so i have a question? i have a Fi BL 12 that i beleive has a blown voice coil (soon to be fixed) but i was looking on the Fi re-cone page and started filling out the details and it asked me about the basket and the stacks? can some one please explain to me what those options mean? Every one input is aprreciated.

Hey i just wanted to know what would be a good enclosure for SPL with 2 12" BTLs.... I Drive a 2003 Tiburon GT and do wanna be able to listen to music occasionally. Thanks for the help

Im in the process of having a box built for my tahoe for a 18" BTL. my boxes dont always come out the way i want so i decided to have this one made by someone who knows what they are doin.. well me being the kind of person i am.. ill bring the info i have from him to you guys and hope to get some support or get me in the right direction. Guy is fully aware of the BTL's and has made several boxes for them in the past. He says he would like to make it 8.5 cubes tuned to 30-35hz and says he will give it a little bit more port area than Fi recommends... does this sound ok to you guys? anyone have something similar or done anything similar. I know here in the fi forums its say…

I am set on getting 2 15" BTLs, but I am trying to get some help from you guys on who makes really good enclosures. btw im obviously a noob

Hello everyone. I am receiving a 12 inch Q for Christmas which I am rather pleased about because Fi woofers are class... I was wondering what I should do about a box, the woofer is going in my bedroom instead of a car but all the reviews I have read about the Q lead me to it. It will be used entirely for music, rock, techno, a little pop, and perhaps some rap to show off a little. The room is about 8x10x8 with a chunk removed that is about a 18 inches by 3 feet for a closet, so not a terribly large room. One of my questions is the great sealed vs ported debate, which would sound better in this application. The Q will be more than plenty in a room this size either way. I…

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…

I have a excursion w/2 -18 Q's and want to know if i can tune them to 30hz instead of 28hz? and should i have the port and subs firing to the rear or facing up? all my boxes always had the port and sub on the same side.I would face them to the rear. I would face my box up and the bass cuts in half. Will this do same if i face the subs up and the port to the rear? I want to get the most that i can get out of subs and box. Any input....

Will 12-gauge speaker wires work with a Fi Q 15 D2? I hope so because I already have those wires installed with my current sub which is going to be replaced
