Fi Technical

My current box pounds in the 30-32hz range and I love it but I also love to compete in local competitions so I need a new box for all out spl. My trucks frequency is 41hz. Can someone help me with the correct box volume and port specs for a box that will peak at 41hz for spl only? The subs are a pair of Fi Bl 18s. Thanks.

ok here goes we have the box made (except for the ports) it's 19.3 cuft after dis. for subs(3 18 btl fully loaded)and bracing, i still need to make the ports........just to give you guys an idea first i cant make just 1 large slot port would have to be 3 at most (med. size ports)and i would like to tune it around 33-35hz oh and the ports would be facing the same way as the subs it's somewhat of a wall/slant design any help would be highly appricated ............................. thanks ahead of time...........................

looking at an 18" Q in a 4cuft sealed box....would a us md-1d be too much for power, or should i look into the bl line?

I'm currently looking at components to go with my 12" BL. I'm going to either go with Rainbow SLC 265s or SLC 265 Kicks. What I was wondering was with my box tuned to 32 Hz would my BL get loud enough up to 80 Hz to be able to have my high pass at 80 for the Kicks? Thanks

Let me know your thoughts My dimensions are as follows: Height- 15 Width- 35 Depth- 21.5 Port Dimensions: HV- 13.5 WV-4.5 LV- 24.75 35 hz tuning... Should wang?

Well I've finally decided to stop being lazy and put my BL in my truck but I ran into a problem while figuring out the port length. I have a 12" BL and I want to put it in a 2.5^2 ft. box tuned to 32 Hz. To do this with 2 4" aero ports they are gonna have to be about 24" I would just do slotted but since the box has to be slanted down on the top and up on the bottom I'm not sure how that would work. So I'm wondering if i could just use one 4" aero or if there are any other thing I can do to make this work. Thanks

Hey guys and gals, I have been slammed at work with all our new server upgrades and 32 new users that we hired, and I am the only network admin for a company with 55 inhouse users, 2 servers, and 21 remote users(<---- the worse part, remote users). I have gone through all my email and Im's, if you have sent either to me, and it hasnt been responded to, please resend and they will be done promtly. Thanks Shawn

i will be buying 3 12" q's in the future with the bp option but was wondering what VC comes in these, the site just simply says 3" 4 layer coil. is this a flat coil, or a copper coil or what, i was reading the coil options listed and it would seem to me that a copper coil would be best in this with it being a SQ orriented sub, but correct me if i am wrong. Will be running these off a Sundown 3000d on a daily set up that will see comps ocassionally wired in a series/parallel combination to right at 1 ohm. FI guys prefered on replies as i am looking at thier view point being that i know they know thier products better than no one else. no offense to anyone else there so pl…

i know you guys are buisy and all but i have been trying to get information on gettin my 18'' BL either warranty or a recone because one of the voice coils only works sometimes. but i have a competition coming up in a couple weeks and i really need this sub fixed in order to get the points i need to go to state finals.

I was just wondering if anyone has some box specs for a single 15" BTL for a 2002 Nissan Sentra XE? Any help would be great. Thank you.

Hello all. I'm getting ready to purchase a Fi Q 12 and a Candence TXA-1000d amp and I was wondering what the optimum enclosure would be for my application. I drive a 97 2dr Exploder, and listen to rock/metal.......lotso heavy stuff. I want the sub to sound as clear as possible when hitting the bass lines and bass drum and still have a nice thump too. So, if anyone has any ideas for specs for me that would be frickin' fantastic! Thanks, Mo

to whom i can talk to about dealing this product " fi car audio" here in our country? i already emailed it at [email protected] but still no one's answered , hope some one could talk to me about this. thank you very much

I am looking to build an SPL box for two 15" Fi SSDs with copper coils... I am just going to switch out of my daily box to this box when I go to competitions... What size box, and tuning would be best? I have a '95 4-door Blazer it will be going in.. I was thinking something along the lines of 6ft^3 tuned to 45hz..

Hi. Has Fi or anybody had any luck with running the ssd 15's sealed. I want to change to a sealed for my next setup. Looking for daily driver/occasional bassracer. Isnt' thomas rourke jr using his ssd 15's sealed? I was thinking of running 4 ssd 15's sealed off my Atomic 5000.1.

ok so I have used a few different calculators and got different lengths... the box is gunna be 4.0ft^3 for a 15" Q tuned to 32 HZ on carstereo.com calculator i got H 6"xW 10"xL 28" on winisd pro i got 6x10x 32.9 L?? what one should I got with or are there any other calculators I should look at? also what would my port area be looking at and would I be in the recommended 12-16" range? Thank for any help -Ryan

I'm looking for someone (Scott? Nick? Just anyone that knows what they're doing) to help me get together a box design (cut sheets, etc)... I plan on running the Q for a little while in a sealed box I built that is right at 2.6 cubes (after sub displacement), but want to build a ported box later so it will hit the lows better. I have no problem with building it, that is easy for me, I just need a good design that is tuned to a certain Hz. I want it to sound good, but be louder from the outside than it will be sealed. Would 32 Hz be a good "middle of the road" tune? The box is going to go in the floor of an ext. cab '01 silverado (still has the backseat, just leaving it up…

Im in the process of designing a box for one Fi Q 15 and I have a couple quick questions. If went over the 12-16 square inches of vent area per cubic foot of volume would this affect the sound Quality? I was just curious because I have seen a few enclosures that definatly go over this and sound amazing. I am going for more sound quality vs. SPL but want to get the most out of my subs. Also I am planning on tuning the box to 32 hz, that was the recomended optimal freq. for the 12" Q but does this also apply to the 15" Q? Any help would be really appreciated. Thanks in advance, Zach

So im about to build my first ported box and i need a little help. My 15" bl will be getting 2000 watts and has cooling and flatwind options. This will be going into a 96 infiniti i30 (same as maxima) My goal is to have the best LSQ setup as possible leaning more towards spl. I think i want to tune ~35. If the box is 4 cubes with the tuning at 35, is a port size of 4W x 13h x 21.8L correct? Is that enough port area? And is that a good tuning for my goal? Also if i use 2 circular ports that are 4" in diameter and 10.5 inches long would that be enough port area and the right tuning? Thanks a lot -Rick

any box builders out there wondering how much you charge for a box for 2 18 BTL FL, flared port, 13ply birch, 5-6 cu a piece shared chamber. dimensions would be 52 width x 20 depth x 25 height that would be my max dimensions give or take a few in. Another guy (Ryan Wallace aka Belunt from CAJ.com) was suppose to build me a box, but i cant get in touch with him now, and im trying to get a refund. but someone let me know something. thanks

Hey, i recently built a box for my 2 Fi X 12's, it is a ported wedge box 4.37 cuft after port and sub displacements. I have a 4 inch ,"precision port", flare port and is 6 inches deep. The problem is that the sub closer to the port moves more and im thinking that i could get more out of the subs if they both had the same movement. A little confused.. i was told that it would be louder if i would have divided the box and but two separate ports, one on each side rather than one on the passenger side. By the way i have them on a Autotek MM1000.1D

hey guys , i recently ordered 2 15 Q's , am going to run them off of a single SAZ-1500D , with 1500rms to both subs. i want to build the box before the subs get here , and had to ask for advice i noticed on the Fi website that the recommended size for each Q15 is 2-2.6 CF. i can give each 2.5CF . will i get good lows? will i lose anything? not enough power to them? im not planning a LOUD LOUD system .. just loud and clear;) thanks. Eli.

ive been asking/emailing for over a week now just for a price on a 10" Q recone kit. and so far nick replied telling me to ask scott and nothing from him. i understand you are busy but cant take a few minutes out of the day to email me back or reply here?

FI website says 5-10 cubes is the recommendation. i will have 1500w on tap and am wondering, what is the difference between the 5 cube box and the 10 cube box. obviously the 10 cube box will be more efficient etc etc. but im more concerned with whether 5 cubes is really going to be enough for an 18? most people build 8 cube+. biggest i can get is 5.5 to 6 cubes, is that size box really enough? anyone with particular experience with this would be especially welcome.

Hello all... after a lot of questions i have ordered my last big toy...a FI BTL 15 full loaded (dual 2ohms) i have ordered a rf 20001bd too .....but at this time it is backorder :Doh: :Doh: so what is the best amp for this sub? new hifonics 2007d ? orion 2500d ? sundown 3000? please helllllppppppppp me
