Fi Technical

so im looking to build a new box for the blow through in my truck. trying to think of some new designs to make it interesting. is there any benefit to having the subs angle towards eachother? i was thinking having them facing eachother down the center with plexi on each end so you can see the inside. thoughts?

Ok i have a 03 silverado extended cab and im wanting to put either 2 12 q, or 2 ssd under the rear seat in a sealed box that has .82 airspace for each chamber and a 7 in mounting depth. i dont know what subs would be best because i really want something that would make people stare lol any advise would be greatly appreciated

Hello Guys. I guess I could introduce my self before i start asking crazy questions..My name is David, I am a Firefighter, I live in Mississippi...I ordered one of the Fi 15 BL with the cooling option, Flatwind option and Universal setup..Daily driver...I am going to be powering with a Xt4000d Us Amps Amp. I have a Honda Civic and I will be using a ported box in the trunk..I have designed a box and was wondering if you guys that see these designs everyday think this one will do me justice...I used some measurements I took of my trunk and how I would like the box to sit...I will 45 all the corners in the box and build it as close to this as possible...Please look and tel…

Besides the voice coil, what are the differences between MT and BTL softparts?

I was told that I could check the sub with a dmm meter to see if its in good condition I got a 1.9 reading is this good, I think so just want to make sure? Its a 2 ohm dvc

I am in need of two 15" recones and baskets with screws for my RE SX's at the moment, I will need two more at a later date. I need dual 1's with some slightly bigger tinsel leads, not the spl ones from the btls, if that is posible. I need the total price for all of that shipped to 47987. Thanks; Andrew

I have two MA XL15s that I want to recone. how do I go about doing that. Must I ship the subs to FI? here is a picture of the sub in case people don't remember them

I've seen that Fi is using woven leads at least on some products, is the Q on of these? Also is this change going to make it over to the AA Havoc any time soon?

Hey I own a 03 Tiburon GT and am planing on putting in 2 12" BLTs with 2 SAZ-3000ds. I want to compete in SPL but also want to be able to listen to music (not as important). What type of box should i get ported or seal and should I get a wall or will it just be a waste of wood. I don't want to do a wall unless it will boost me db. Thanks for the help, I don't have a clue what to do.

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 2003 Gmc envoy, and dont know what i want to put into it, was thinking either 2 of the 15 or 18'' btls and either 2 of the RF t2000 bd or 2 of the t4000's any ideas what would be loud and still sound good?

Can someone give me the screw hole diameter of the 15" Fi BL? I saw the outer diameter was 15.625" but did not see a screw hole diameter. I am working with limited height and don't want the screws to be lined up on one of the boxes wall. Hoping I can save around a 0.5" inch on the height just having the outer surround overlay on the outer 3/4" edge of the box. Thank you for any help! I would measure it myself but I am ordering the woofer in the next few days and want to start the build now.

I have 2 rockford P2 15" d on a TMA amplifier 500.1 in a 4.5 Cu. Ft. Box ported. I'm in the process to get 2 Bl 12" d2 and I need the know if the HIFONICS BRUTUS BXi2608D will be a good option (cheap one) in a 5.0Cu. Ft. This will go in the trunk of a Toyota Yaris 5 door. My budget is pretty tight, that the main reason why I decided the BXi2608D. Here are the pics of my trunk Visit My Website

what fi specifiacations (dual voice coil, hixm, etc) shoud i pair up with a 2600 rms hifonics?

Hi yea i just got my 15" BL.... Thank you Fi Audio for a nice and fast delivery.... Now my question is, for anyone who owns one of these u kno how heavy that thing is so i wanna kno what kinda screws should i use or bolts, i dont wanna use basic screws i feel that this sub will just break them like toothpicks.... I cant wait to hear this bad boy in action Thanks

So if I get a DVC 2ohm BTL that means there are two voice coils, which just ONE can handle 2kwrms correct? So if I hook up 2kwrms to each, shouldnt that work? Or lets say 1500 on each coil for less heat? Yes yes I understand Im retarded, but you never learn if you never ask P.s. figured out my other question..

Has the title states, how do I get a 1 ohm load with 2 btls? My first previous subs where dual4 so I wired them in parallel. Do I need dual1 ohm? If so how do I wire them? Thanks.

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

I'm going to run 2-18'' BTL's each in there own box with 2500 watts to each sub. I would like to know if 6 cubes each would be good for the power that i'm running or should the box be bigger to reach full xmax? And do you have to add the ports size to the size of the box or not? I know you add the sub displacement to the box so do you add the ports to??? Want to run 2-6'' Precision Ports pre sub tuned @32hz. Does this sound like it would work? Want LOUD DEEEEEEEEEP BASS. And what is the disp. of a fully load BTL? Any help would be great.

when u enter the box design posted on the forums for the ssd into the re box calculator i get a tune of 30 hz ??? is this right cuz i need to change the dimensions a bit for it to work for me i making a rear center console for a 10 ssd. and also i can only seem to get 17" of port area not the 27 i assume i need will this be a problum ??? and also i will not have a L port just a straight slot. any suggestions or help would be appreciated thx

what does Universal option do to the sub frequencies response? will it make the SPL lower since the motor is not optimised for the coil impedence chosen? or does it give the 'peaky' effect like flatwind?

I'm looking for specs pertaining to a STRICTLY SPL setup using two BL 18's. What should the port be tuned to? How much airpsace do you recommend if I'm using a single chamber and acoustic coupling?

i want to know if 1 fi x 10" is good on a 200 watt amplifier. and what dbs could u get out of one

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 have a mazda ext cab pickup and have about 12cu feet to work with. I really want the FI Q18's. I have never owned a pair of 18's and that's what i want. I want to kind of do what Steve Meade did in his honda and build the enclosure inside of the truck. If i can't do that this is the space i have to work with 30in high x 49in wide x 14in deep. If i built inside i think it would be a little bigger. I was wondering if I can't fit 2 of the Q's, should I just use 1 of the Bl's?
