Fi Technical

Well im running my 15 q ported right now and ilike the way it sounds but i was wondering how many of u are running them in a sealed box? I know the ported would most likely get deeper than the sealed but i was wondering hwo much of a difference it would be sealed and what other peoples opinions on the q sealed are. I do listen to alot of rap thats why i went with ported. Was wondering everyones opinions on the ported vs. sealed. thanks

I need your help guys..... 1. Sealed or ported? 2. Does any one have a pre-fab box that works well? 3. Does anyone have box specs that I could duplicate?

My sub sounds like ass in the box that I currently have it in. Waaaay too much port noise! I am only running a single sub right now, but I will have two Q's pretty soon. I am in desperate need of a box design to fit my needs, my parameters are as follows: (Max Dimensions Given) Depth - 15" Height - 16" Width - 34" I need the box tuned to about 32HZ. I would like to keep the chambers separate, as it might be a while before I buy the other sub. I would like to hear what the first sub sounds like before spending more money on another 1. All help would be appreciated. You can PM me on caraudio.com under Qbenjamin.

I was wondering which setup would fit better. i currently have a kicker 750.1 and i was planning on gettting a fully loaded 12" duel one ohm sub and running it at 2 ohm. I was wondering if that amp would be enough. If not then I plan on getting a fully loaded BTL 12" duel one ohm sub and running it with a Lanzar2000D. Thats supposed to put our 2000watts @ 0.5 ohms CEA rated. Which setup would work out better?

i currently have a 1997 mercury mountaineer with 2 q18's. i plan on walling it off behind the second seat with 4 q 18's. heres the problem i run into...the depth from top to bottom of the center of the back is 37.5-38 inches tall. but at the very back where the hatch shuts it drops to about 30 or less inches roughly. how would i go about building a wall with the subs on the same plane and port as well. i wanted to do the port in the middle with a pair of 18's on each side. but how would i get my box in. i want to avoid the pacman style boxes if at all possible. please help thanks. i know there are others out there with their explorers which is the same thing running 4 18'…

Hello all, I purchased a Q12 years ago and unfortunately for the life of me cannot remember if it is the dual 2 ohm or dual 1 ohm. There doesn't seem to be any markings on the sub or coils...how can I tell what I have? I could have sworn it was the dual 2, so I wired it in parallel to put a 1 ohm load on my amp. It sounds great, but the amp is going in protection mode when I turn it up. The amp is 1 ohm stable. So I pulled the sub out, wired it in series...which would put it at a 2 ohm load (if it was in fact a dual 1). No matter how much I turn it up, it stays on just fine. Problem fixed, right? Wrong. The sub sounds like crap now! As if the polarity is wrong or somethin…

My friend is buyin a Fi Q with all the extras and we were wandering if any body had any old box dimensions and i dont want the dimensions from the website Q 15 – We recommend using a sealed box in the neighborhood of 2-2.6 cubic feet of volume. Ported box we recommend using 2.8-4 cubic feet @ 28-33Hz. Again use 12-16 square inches of vent area per cubic foot of volume. so plz if u have some dimensions for an 15" Fi Q ported box Thanks

The motors on these woofers look almost identical. I know both woofers are made out of the same build house. Is there any difference in the motors? I know Xcon is more of a sound quality woofer, Im a owner, and the BTL is more of a SPL woofer. Is it the soft parts and the coil that make them sound different? Please excuse my ignorance on the subject.

So i picked up my 18 inch btl with hiXM coil and cooling options(DAILY). Now for the amp. Normally i would say that i don't have the money for the SAZ-3000D, but i found it online refurbished for the same price that i can pick up the Rockford Fosgate t2001BD from sonicelectronix. I read a post from a guy who got the refurbished SAZ-3000D and he claimed that it was functionally perfect so i wouldn't mind purchasing it. both are about $560. I plan on doing all the elcetrical upgrades necessary for either of these amps (big 3, Kinetic hc2000, high output amp, all that good stuff) now my only concern is that my sub is the dual 2 ohm and i will be running it down to 1 ohm like…

Finished the recone on a fully loaded BTL 15 today and this thing sounds even better than what I wouldve ever guess... I have one question though... I brought the sub to a friend who owns a shop to get the recone and after playin it a bit... Pulled up to a friends house and noticed the dust cap fell off, so I bought some more epoxy 5 min loctite and put it back on no problems. After expecting my little glue job the dust is maybe 1/16 of a inch off from where it used to be. Will this hinder the subs performance at all? Its sounds fine to me, still loud as chit...(My wife said it sounds like a machine guns going off in the trunk.LOL) this is only a temp system... Next syste…

Since both the Fi BL 12 and BL 15 are 1000 watts RMS, and I have about 1200 watts to play with, which should I get? Would there be a huge difference? And on a completely unrelated note, how do you guys go about bolting down your enclosures in your trunk? I have a 06 Sentra and below the carpet in the trunk is the spare with a piece of cardboard over it. Now there is about a foot of exposed metal running down both sides of the trunk. Just curious about how it's done. *Guess I should have asked first, will a box for a 15" BL fit in the trunk of a Sentra? Thanks.

So would I be better off gettin an Ssd or bl? I'm jus getin one fifteen and I'm not lookin for sound quality jus wanna shake houses and go deaf and also I hav a Pontiac grand am.. Wuld the subs be better firing up.. In the cab? As of now they are facing outside(ATM I have 2 12" inch kicker cvrs powerd by 1000 watt kenwood in a pretty big ported box takes up most of my trunk)

Hello all. I am currently running my 10" Fi ssd woofer in custom built ported box (sub up/port back). I love it! I have a kid on the way and would like to switch to a smaller sealed box for more space. I have a couple of questions: 1. Can purchase a prefab box that meets the recommened specs? 2. What size would be optimal? .6-1 cubic feet is what is recommended but would it be better to stay on the .6 side or the 1 cubic foot side? Thank you in advance...

what is the speaker wire gauge for a Fi BTL?

Hi all, I just recently switched my Q10 from being sealed in an ext. cab S10 to .9cuft port enclosure in an '88 BMW 325ix. I took a ton of time designing the box for the bimmer because I was looking for more output down low so I shot for 27hz using 4in PVC. I got it all built up and installed and I'm slightly disappointed with it so far. Things just don't seem loud enough. I figured going ported AND in a larger cab compared to the S10 I would get more output but I'm getting significantly less. I must add, the enclosure is sealed up to the rear firewall firing into the cabin of the car through the ski pass hole so I have zero trunk rattle. I don't know how this would affec…

What are the wiring options for the D1's? I can't find any charts indicating the wiring options for a D1 sub.

i should be getting a 18 btl any day now so i built a box for it i have somewhere around 6 to 7 cubic feet not including the ports iam wondering how to get the box tuned at 32 to 35 hertz is it the cubic feet for which the box is made or is it from the amp and cd deck ?? any help would be usefull thanks yall

Alright, so i finally have all the pieces together for the btl. Alternator, battery, amp, wiring, ect. So now to this whole... building my own box thing. i would prefer around 32hz and 7.5-8 ft^3 before displacements for sub and bracing. I have 3/4 inch MDF (its actually 11/16ths). So one question is how do i brace it properly? And... i need box calculations for a standard Sub facing up, port facing back of vehicle design. I really like Mac n' Cheese's idea of coating the inside of the box with resin, i might do that. so 7.5-8 cubic feet, 32hz, and the dimensions i have to work with in the back of my explorer are 44.5" wide, 25" tall, 22" deep. Maybe 30" tall if it make…

My 12" Q should be delivered tomorrow according to UPS. I'm trying to decide on either a sealed or ported box to go under the rear seat of my Extended Cab Silverado. I've never run a sealed enclosure in my past 2 setups, and I'm skeptical as to whether I will be satisfied with the output of one. Any suggestions or opinions would be appreciated. Thanks!

I have a bmw 328xi sedan and im gonna be running a single 12" fi q in a sealed enclosure because i wanted more sq the sub has the high qts option and the heat ring the website says .8-1.5 cu. ft what im wondering is what would be optimum size for the best sq for a wide range of music.

someone on another forum posted about more thiele parameters then wats on the site says he wants to know everything plus motor strenth can yu guys help out

so i have a d2 bl that will be on a saz1500 and was wondering on basic guidelines for a box. im looking for input from those who have played with em, or can tell me from other experiences whether or not 2.0 w/ around 40^2in of port would be okay. with the sub and amp in consideration should i go bigger/smaller, more/less port?

im thinkin of gettin this planet audio big bang 2 1400 that puts 1000 @ 2ohms ive read good reviews so this is just to seal the deal.......any info will help thanks

What is the difference between Running my SSD 900RMS@2ohms or Running my SSD 900RMS@1ohm. I think it has something to do with efficiency?

I know that you don't sell ib3 8" subs . But could you and at what cost ? Looking for one for the rear deck on my Lexus .
