Fi Technical

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

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.

Hey guys, After putting my 15" BL together in a 3.5cuft box, which sounds awesome, now I just have to fix my amp problems. Anyways, I have to build a box for a friend for her 15" Q. I suggested sealed since she wants to do more stuff in the trunk and I didn't want to take up the whole trunk like my box! We both have Scion tC. I was thinking a box for the 15" Q sealed with the exterior dimension of 12" high x 32" wide x 16" deep, with 3/4" wood. That will give an interior volume of 2.69cuft w/o sub displacement, so with the sub it is 2.5cuft. The sub will be powered by a Kicker sx1250.1 amp, that amp supposedly gives out 1250 watts at 1 ohm. So with that given se…

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…

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

I have a 04 Honda Accord sedan and I was looking @ the 15" Q which would be daily. I have a couple questions 1. 1ohm vs 2ohm (amp running about 1000-1200 RMS) 2. SQ wise should i go ported/non ported? 3. I don't know if a 2 cube box would even fit in the trunk any suggestions @ all, im new to car stereo if you didn't already know lol. ANY INFO WOULD HELP! thanks, -B

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 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 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

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.

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

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?

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?

Is the recommended sealed cabinet size of 0.2 to 0.6 cu ft after displacements given in 2007 for the high QTS driver. Also does anyone know what the high QTS is

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

i have a budget of $500 for an amp can anybody tell me what would be better for a 18" bl and 18" btl i will appreciate any help from anybody. thanks, Jose

I was just wondering which is best on the Fi Btl the dual one, or the dual two, an if order the universal what does it come set as or what? Please help me before i order thanks.

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.
