Fi Technical

Hey guys, I have Manny from http://www.trexcaraudio.com/ building my box for 2 18" btls..and I was just wondering if this sounds correct, his calculations for the box: 19" high 40" across 37" deep 95 sq ins port is 13" long (tuned @ 32 hz) and is 11.79 cubes thnks, Freddy

Ok, I am used to building the everyday run of the mill square sealed boxes. I have a 4 door truck with the 60/40 split seat, which I will be removing the 40 section and building a box with an upward firing sub...but I am thinking of porting this one. My question is, can I run ports out of PVC that sit about 2" inside the box and run external under the other part of the seat? Trying to think of some options to possibly install a 15" BL instead of a 12. And the volume of the pvc pipe should be equivalent to the total recommended port in the BL specs correct?

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?

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 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??

im looking for a ported box for the trunk of a 95 caddy, 14"H 14"D 38"W is the max for the box. it's for a 12" ssd how long/big should i make the port to tune it around 33Hz's it also going to be powered by an alpine 650 watt amp.

does an one know the displacement of a fully loaded BTL the web site say .26cuft but thats not with the 3rd slug, just tring to get as close as i can so that way my port will be as tuned as possible, or is .26cuft close enough

I hope this is posted in right place.... Two questions: 1.) What is the RMS and peak wattage for a single 12" BL with the dual2, flatwind, daily and pchamfer options? The reason I am asking is because I seen on Fi 's site that it says 1000w/rms, but everyone is highly reccomending the sundown 1500d (which i am about to get.) So, why is that so if it is only rated for 1000watts? Does adding those options bring it up? I had a new custom box built by Sound Advice here in florida and the guy who was instlling it says to me that I will not notice too much of a difference in swithcing from a RF Punch 1000w/rms amp to a 1500 watt/rms amp ( in this case to the sundown 1500d)…

first off i have an 18" fi q with the bp power option and a hifonics 1610d amp. its in a focus, and it will b in a 7 cubic foot box hopefully, but my question is that i want to use pvc ports instead of the normal slot port, i used the winisd program, but either im an idiot, or its really hard to use. i put in my t-s parameters for the q and then i set it to 7 cubic feet and put the tuning at 28 hz. then i changed the porting to round and put in that i wanted to use 2 4" ports. it says they need to be 9.25" each. is there nebody out there that can check that for me to make sure its correct? any help would be greatly appreciated. thanx.

I have a 12in fi bl fully loaded and a sundown saz1500d with all 0g wire and stock electrical. My alternator is 110a. Im not sure what I will need to do to see full power from the amp. Would the kinectic 950 be enough for an extra battery in the back?

This is to FI, What are my options on reconing a TC 3hp motor to a 18"??? I need it reconed to a dvc 4 ohm. What parts will fit?? Could you pm me a cost of the recone if I send it in thanks, Joe

I got a baffel cut for my 12" box so I could convert it to accept my BL 10", I have a box uilt to spec for the BL only its for 2 BL's. I have not got around to ordering the 2nd (money) so I had to put it in something else until I get the second. My dual box is common chamber, so I cant run it that way without the other sub. So, I put the BL in the 2.15 cuft box powered by my 9.1, 1200 rms, its very loud and low, only, I know its not good for the sub to be in a box thats too big. I hear it will make the sub super efficient (spelling) , I am thinking to add some MDF to the box to shrink it down or run the sub at 4 ohms (450 rms) until I can get the 2nd one for the dual inst…

hi all i was wondering if anyone new the le:, z:, and pe: of a fi Q 18 because i need them to design my box on winisd and fi doesnt have them listed. thanks

Im going to put a 10" bl under my rear seats and need to know if it will fit. My box is going to measure 7.5" in height and the bottom of the seat is 9.5" tall. Is 2" enough room for the excursion of the bl? If not should i use 5/8" MDF or 1/2" MDF

Hello everyone It has been awhile since ive las longed on to this accound but now im back. I got a Fi Bl 15" about 3 yrs ago and i would have to say it was the best/ loudest/best built sub ive ever come across. I had my box made by a guy out in Canada. His company name was Pound That Sound. Since i havent been on this website in awhile ive noticed that he no longs makes enclousres.... Ive been looking around for someone to help me with my next built since ive gotten a new car. Im sticking with the BL and i going to have the same set up likelast time, 1 BL 15" w/ hyper pole option. Now my question to anyone who wants to answer is... is there anybody you would recommend for…

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.

Well I just had a box made for my 15" BTL and they kinda messed up...first they made the woofer hole facing up and the ports facing up also....do the ports facing away from cabin sound louder? Also i found out that the box is tuned to around 29hz....how will that sound?????? Will it sound good..will it be loud most also? I listen to mostly all rap just to let people know (i know rap sounds better in different boxes hz wise)...The box is around 4cuft also just to throw that out there. Help is much appreciated thank you. Here's some pics. Inside...one of the ports.

i need 2 mt recone kits for my 15's i will also need the glue and i would like to have them dual 2 ohm plus i would like to have the fi dust cone can any one help me out with this i need to order these asap no response on web site

Hello I have a jeep srt8 with two rockford fosgate 1500.1 bcd's and four rockford p3 15s in a custom box tuned to 35 hertz. I want louder now. I've been hearing alot about the fi subs. I wanna keep my amps but get four fighteens that will do great with my amps. Both amps comined will do 3900 watts rms. I've been looming at the fi bl line. They are rated at 1000 watts rms 2000 peak. So if I had four Of them they would be 4000 watts rms , I would only be shorting them 100 watts. My question is can these amps slam the bl pretty hard and can I use my same enclosures I have now with 12 cubic ft and , 6.1 per chamber for two subs on each side and tuned to 35 hz. Basically each…

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

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

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

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

I ran 2 bl 18's off 2 sundown 1500d's for little over 2 years with no problems at all. Those bl's had cooling, flatwind, daily options. Now they offer to have a 4" coil for extra $50. This time I will be running either an aq or sundown 3500 on 2 18's. With the 3500d should I go ahead and get the 4" coil, Im pretty sure the 3" would be fine since I ran the others with no problems that long. thanks for suggestions
