Fi Technical

ok guys i have a RF BD1500, birthsheet 1740 @1ohm, would 2 12" Q's or 1 15" BL be louder?? or is it possible for that to move a BTL a sufficient amount?? and also could you tell me what options to go with please and finally if i get a duel 1 ohm, does that mean the amp sees it at .5 or 1 ohm? and the duel 2 at 1 or 2?

I was originally talking to Scott about a Q 18 in my h/t setup, but I have a chance to get a used SSD 15 instead. It needs reconed, so I was just wondering about the best coil for the recone, and a few questions. I was planning on asking for the copper coils with the recone, but I was just wondering if it would be best with my setup. I was goin to use one of the following plate amps with it, so around 500rms at 4 ohms. Bash 500 http://www.partsexpress.com/pe/showdetl.cf...tnumber=300-752 Dayton 500 http://www.partsexpress.com/pe/showdetl.cf...tnumber=300-806 At the moment I'm leaning more towards the Dayton, but I wasn't sure if it was worth the price difference. Also cou…

WHICH DESIGN WOULD BE BETTER THE SUBS SHOOTING UP WITH THE PORT AT THE BOTTOM SHOOTING BACK, OR SUBS AND PORT FACING THE SAME DIRECTION.

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

I have a Fi BTL 12 running with a rockford fosgate amp but I've been wondering what I'm supposed to set the frequency knob to on the amp near the gain.I think it goes between 80hz-300hz. I dunno.any info anyone?

Would there be any noticeable difference between making one huge box or leaving both of them in separate boxes, advantages? disadvantages?

Does anyone have a contact number for them?

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…

Can somebody post them up? Trying to see if they'll work on my rear deck using the 19.1 cubic foot Cadillac Deville trunk...

Hifonics TXi1508D- Titan Series 1500 Watt Mono Amplifier pushing an 18 fi bl

Basically I'm stuck between two designs. The first one is 4.3cf with a 6" flared aeroport tuned to 35Hz. The second enclosure is 3.5cf tuned to 32Hz using a slot port, with 54" of square port. The power is 1000 watts rms at 1 ohm.

I have my 18 bl and my car now so im ready to construct my box to fit my trunk. Ill be running the sub and amp at 1000rms at 32mhz. The trunk has alot of space but im worried about putting the box into the trunk so if anyone can give me the proper dimensions for 32hz please let me know and does anone know a good calculator tool for this so i can calculate the port size also? THANKS!

So I just bought my new car, a toyota celica, and I am going to have a custom box built for my q 18. with a kicker zx750, how many cubic feet should I go for? I am looking for a flat frequency responce and a good balance of sq and spl. I know these are all really rough terms but I just could use some advice.

I am looking for sound quality mostly, not worried about if the bass rattles my car apart. If I go sealed would it be terrible if I went prefab from online? and if I went ported I am thinkin about 2 cubes at 30 or 32 hz. how big of a difference would trupan-lite over mdf make? thanks all

what's the sub displacement of a btl 18 tripple stock magnet? thank you

Was going to order a couple 2 ohm recones for my SSD's but now there is the basket option of yes or no. Didn't know what this meant. Can someone tell me please?? Thanks!

I just designed my box and came and up with 12.37 sq inches of port per cube is that a little low? What does more sq inches of port per cube do? I also came up with about 4.03 cubes per sub before displacment I want to do a little larger what does everyone I think? My dimensions I used are 23width x 34height x 49 length. they will be in an 05 f150 with two kicker zx1500. 1 amps powering them for now will upgrade power. I know they give generall recomendations of 3-5 cubes per sub and 12-16 sq inches of port per cube. What is everyone else running? and what should I tune to? I did 27 hz my amps lowest is 25 hz and the way I understood what fi said was 2 above your amps lo…

hello im from turkey..there is no fi sellers in europe i wanna make order via net and got some questions.. whats the weight of fi btl s aprox? which amp do u suggest for this monster?i only know 3 for this baby first one kicker zx2500.1 second ground zero 1.3000 and last one hertz hd1k and u can suggest good ones if u know something kick ass for this btl..

Sup guys. I currently have 2 15s in my car and the box is around 4.7 cubes. If i got 2 15inch btl fully loaded subs would i have to increase the cubes of the box? Thats my max cubes that can fit in the car

Hey guys. I plan on purchasing two 12" Fi BL's. I will be powering them with two NINe.1 amps.....those are my plans. any other suggestions for amps are welcome. But the NINe.1's fit my bugget perfectly. I need suggestions for a box.... Ive been messin around and came up with this box. I will 45 all of the corners and seal her up tight. Should this box pound alright, but still sound dec.?? thanks here's the link http://www.subwoofertools.com/forum/ported...;Fs=27&CE=0

I will soon be purchasing the Fi BL and was wondering if I will have to upgrade my electrical. The amp I will be using is either a sundown 1200d or audioque 1200d. Thanks

Configure Speaker: Ohm: dual 1 dual 2 P Chamfer: no yes +$10 Cooling: no yes +$40 HiXmCoil: no yes +$20 Daily or SPL: Daily SPL Induct Heat Ring: no yes +$25 Universal: no yes I can't seem to find what these options mean and/or how eeach affects the end product and I would like to order a couple of the Fi 18" BLTs. I will be playing them daily. Does anyone know where these options are explained so that I can decide what to choose and why?

i have a 15" btl fully loaded. i want to compete in bassrace and maybe just for spl burps wise. i have about 5 cubes to work with. i kind of want the box to move alot of air for shirt tricks and hair tricks. is it possible to get high numbers with the two i want to compete in and still move alot of air like others do with this sub. just curious

Does anyone know what the hyper pole option on the 2009 fi bl is?

i have a center console box for the rear of my crew cab titan.its 1.7 net and i want to do 2 BL 10's.after sub displ. its .7 per sub.my port is an aeroport.3"x10" so that 30 sq.in.will this work and sound good?thanks
