Fi Technical

It is 2.375ft/3 and tuned to 30Hz. I mostly listen to rap and some techno. Is this a good box for a Fi Q 12? http://www.caraudio.com/forum/showthread.php?t=280672

Anyone have custom box dimensions for two 15" ssd?

Can FI do this to my Conecpt PT's? Sorry that i posted this but im sure someone can answer me faster then emailing them...

Guys, I know the BTL enclosure recommendation for the 15" BTL is 3-5 cubes net, however I also know that required volume is also dependent on power supplied. I was wanting to know if there would be any problems with running (3) 15" BTL's in a 8 cube net shared chamber enclosure? I should have roughly 3500 watts on tap for each sub, but I will not submit them to that much power, I was just wondering what I could get away with in terms of enclosure size? This is a daily beater.

This is the box i'm gonna start to build this weekend if everything works out. It's gonna house a FI BTL 18 Loaded. Tell me your thoughts on the design good or bad thanks everyone for your input

Well, After serching the forum, I have found what is included in a recone kit, but now its time for the questions. I was woundering what a 18" Dual 2 ohm BTL recone with flatwind coil will cost. Also I have never done a recone before but I beleive I do have the logic, and patience to do one, but would I be better of just sending in the motor and basket for a recone? Would it cost the same for a recone kit as it would to send in the sub (Shipping not taken into consideration here)

I have 4 15" kicker's in my car right now running off 2 hifonics 2006's. i am thinking about putting either 4 18's into a truck or 2 18's of the trunk of my car. i want to flex and have a lot of bass. i already sound loud i my car but i want more. do you think i am jumping out there to far with purchasing 4 fi btl 18's? and if so what sloutions do any of you have for me to get flex and more bass? I will probably using the same amps or buying the slightly higher rated brutus. Oh just fyi the car is a lincoln towncar

well like i stated on someone elses thread, my tinsel lead broke and i really felt the woofer didn't sound the same anymore. i was just looking at it and noticed that the surround is starting to crack around where it meets the cone. and i also need a terminal which i broke a long time ago. my question's.... do i order the recone an do it myself? never done it, so i'm kinda wanting to try it. do i send it back to fi and have them do it? i built a box for another guy in hawaii that has a btl and was wondering if they could do my tinsels like his? or, do i buy a new woofer, because shipping back and forth might be kinda pricey? any and all suggestions welcome and …

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

Hey I tried doing a search...I kept getting an error anyone know the specs on a TC7 motor?? I am probably going to buy one because of a good deal on it. What size coil does it fit?? Will a standard 12 spoke basket fit it???

I have a pair of 10" BL's and chose the SPL option when I bought them. I had no intentions of playing music with them, but now I wonder if they'll handle playing music for a short period of time. I was thinking of trying Bass Race in Db Drags next season but don't want to have to buy new subs in order to do it. Does anyone know if these subs with the SPL option will handle music for 30 seconds at a time at full power?

Hi, Ive got a MTX TA81001 amp that pushes 1500 watts at 1 ohm and im going to run a 15 inch Q. Do i need to get the BP option or will it be fine without it.

whats the most power you could safely put through a btl 18 loaded, and not blow the coil? im just wondering what some have tried and found to work where as someone might have tried ____ and blown said sub.

I just ordered a FI ssd 12 inch subwoofer, a Kicker zx750.1 amp, and 4 ga wire kit. I previously built a 4.0 cu ft box out of 3/4 mdf. I was wondering if the ssd would be alright in this box. Also how long would the port need to be if using 3" dia. pvc pipe so it is tuned to 33 hz? Thanks.

Do you guys offer a recone kit from Fi that will fit the RE SX motor? If so, could you PM me a price please? Also, would you be willing to sell the recone + motor for a Q? Let me know!

I am looking to build a slot port box very similar to the threads that are very recent in the forum. My dimensions are slightly different and I want to flare the port walls which will complicate things. My dimensions are: height: 14" width: 30" depth: variable tuning freq: 32 hz box volume: 2.3 cu ft subwoofer: FI Q12 Dual 2 amp: Soundstream PCA1500D Like I said I would like to flare the vent sides by cutting slits in the MDF and bending it. I have made some test bends and they seem to work out pretty well. I have read that adding the flares will require an additional 1-2" of port length. I can add the additional length that is required for the flared p…

I'm sending in my 3 hp motors to be reconed on WED. I need a addy to send them to. Also I believe its $148 to have them reconed to 18's including shipping each. Correct? So I you could let me know where to send them, and if its ok to sen'd a m/o with the motor, or would it be bast to calll me and I'll pay over the phone with my Debit card?? Thanks, Joe. P Also The 3hp's have the tall top plate. would there be any benefit to miacine cooling channels in the top plate?? Could you do a fully poly cap on the 18" recone(like a havoc), I've seen 1 done, and a 10 with a poly and Fi logo, I'd love to have a full poly with the FI logo. Would look great..

ok so i have a 15" ssd with copper coil and a us amps md 23 i ordered a audioenhancers ported box for it that was close to the required specs, but i got sent the wrong box. the one i recieved lookes to be 2.3ft at anywhere from 34- 38hz area will this work or is it going to be to small???

I own a 2003 Mustang GT, and am trying to get the best system I can in it. I have VERY limited trunk space and so chose a single fully loaded 12" BTL powered by a Kicker ZX2500.1 (2500 watts RMS into one channel @ 2 ohms). I also have a kinetic 2500 in the trunk. The trunk opening is too small to get any sized box thru so I'll be installing it thru the back seat. The opening is 13" high by 32" wide, and 28" deep. I'm looking for a ported box to get the most bang out of the sub. Anyone got the best design for the BTL with the max dimensions (13x32x28)? Thanks.

i'm looking for a speaker box plan for my fi bl 18. would this box work or should i go bigger? http://img35.imageshack.us/my.php?image=5c...hz62sqin6hk.png

Before anything, how much power will a Q with BP cooling handle, if gains are set properly, no audible clipping, etc.? Okay, first off, the SSD should be louder then the Q, IN THEORY (disregard the box and everything), due to it's higher sensitivity, correct? Second, the SSD is known to be heavy on the low end bass, but a bit lacking in the higher freqs. How does the Q do? Will the Q slam as hard as the SSD? In other words, will the Q reach that ass-dragging low bass that rap music is typical of? Thanks, I'm going to ask a couple more questions based upon the answers I receive to this, so check back. -SteveSan

What is the best option setup on a BTL for SPL use only and how much power will they take for Burps only?

right now i have 1 12" ssd fully powered in a ported box. it is 16X22X14. it sounds good and i listen to almost everything from rap to techno. I was wondering if it would be better to switch to a sealed box? i mean one advantage would be less used space. and which direction should i face the box also...

im trying to stay with an enclosure that is 3cf or less and trying to decide whats better, 2 12s sealed with 3000watts (buy a new sundown 3000 amp) or 1 12 ported with 1500 watts (keep my mtx 1501d)? if the sealed subs would be louder, how much louder? last option is 2 10s ported. looking for LSQ, basically the loudest set up i can get with the space available. appreciate the help!

Would be grateful for any help. I just got my 18 btl in the mail and would like to start to build a box. I have built alot of sealed boxes but haven't built a ported box. I drive a 98 tahoe so size is not a problem. It will be used in a daily setup would like to tune that way but get loud thanks for any help
