Alright well im going to be getting 2 18" FI BTL's reconed(The older version) and was wondering what kinds of new options I can get like diff dustcap or diff tinsels stuff like.....that Id want carbon fiber if posssible and also what are the prices on diff options...any tips on packing for shipping?

Hi, i recently bought a recone kit for my Btl. It was a 12" and I am upgrading to an 18". I cut the surround and spider to remove the cone. Now, i see the screws holding the basket to the motor. Simple, right? Well i cant get the screws to break from the motor. They were soldered on to the metal. I broke the solder with a screwdriver, and now i'm left with six screws that WILL NOT budge. I really put some power behind one screwdriver and the screw started to strip on the top. Any ideas?

Sent an email, and with all the set backs I've heard about with the email provider you use, I thought it might be easier for you and me to put up a thread about it here. It's a 15'' and I would like d2 coils. Was just wanting to know how much it would cost, and if it's possible to get the person whom I'm trading with for it, to ship directly to you, and you ship to me. Thanks, Jonathan

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 have 2 15s btl. 1 is dual 1 ohm, measured 1.5ohm on each coil.(working) both 2 magnet motor. 2nd is d2 , measured 2.5 ohm. (blown) d1 sub, the pole is black color , i think that means its universal. d2 sub blown, doesnt have black colored pole. Question is can i recone d2 with 1 ohm recone kit to match my other btl, and will they have same specs? plz help me out.

Before my son was born, I was running 18's and I really miss the output of that setup. So I am thinking of sending in my 12's to get re-coned as 18's, or if its not to hard, just doing the re-cone myself. Yes, I am tempted to off load the two 12"s and just get a 18' xcon or BTL, but with hardly any more power, and 1/2 the cone area, this setup should be louder theoretically. Secondly, I am not a box designer at all and I am completely lost as to what works and doesn't. This is a daily setup. I don't compete. Using RE's Calculator just as a ref, it looks like the max volume I am able to get is around 13.5 cubes before displacement. That is leaving a bit of space between…

Well I am gonna be going for my first recone attempt. It will be a BTL. I am feeling pretty confident but have a couple of questions. First thing How do I properly clean all the excess stuff from the original BTL. Like the surround on the basket and where the spider is glued down at. I was told just a heat gun to get it loosen up so I can just pull it all off? Second I hear alot of people talk about the "Triple joint" and how well that is glued. What is the triple joint? Also I am confused on how to properly "shim" it. Is it that the shim alligns it properly so that it doesnt rub? If so that means the paper shim is only making like a hairline gap? And wheres the best pl…

Hey, I sent you guys a konaki motor about a month ago with an invoice of what I wanted. Just wondering what the statis of it ? The name is Jason Leonard if that helps. I left the invoice in a pouch outside of the box will my contact info, email address, payment options and what I wanted. If you could just reply to this on the statis of the motor/woofer. Here is the tracking number --> 1ZE4E0710335401132 Thanks -Jason

HI. How many costs RECON to BTL + shipment? How long are they waiting for RECON? How to order RECONKIT quickly from the FIcaraudio company? I sent 3 messages Email to the [email protected] address and silence. Nobody is answering please help my BTLs 18" ; Ohm: dual 2 P_Chamfer: no Cooling: yes HiXmCoil: yes Daily_or_SPL: Daily Induct_Heat_Ring: yes Universal: yes

Is there like a list of subs that you guys can recone? or is it just american sizes? or what? Are there any rf's able to be reconed? or are they all foreign motors of some kind??<----T1's????? i want some ssd's soooooooooo bad but i need some $$$ and ive got 2 toasted T1's sittin here, jw wonderin if i can do anything with them instead of sending them to rf for $104 each plus shipping which is like $40 each, each way---- $400+ haha Thanks

I originally bought a FI Q 12" dual 1 hoping to run it with a JL 1000.1v2 so I didn't really think much or care if it was dual 1 or dual 2. Unfortunately for my plan the 1000.1 would not of fit due to space restraints where I planned to mount it in my car. I instead went with a Sundown Audio SAX 1200Dv2 running the 12" Q @2ohm with ~700 watts. I find that the bass is adequate but when I look at the cone I can tell the excursion is not what it could be since im running it underpowered. Im wondering if I should sell the dual 1 I currently own and instead buy a dual 2 and run it at ~1200. What amount of DB sound difference would I be looking at? How much am I losing out exac…

I am about to build a box for my incoming BTLs. I reviewed the cut out sheet for 1 BTL that is provided on the forum but was unsure as how a box for 2 BTLs is supposed to look like. I am unfamiliar with how the different dimensions in a ported box affect the performance of the sub so I would appreciate some input. 2-BTL 12 4.9 cubic feet @ 32Hz

My amp is going to be a 1500d, for sure. Two SSD12s have a recommended ported volume of about 5ft^3, and a BTL15 has a recommended ported volume of about 5ft^3 as well. I understand the two 12s will move more air, which may be more impressive as far as my budget will go, and being realistic, I don't anticipate being able to buy another amp or the surrounding electrical to back it up for awhile. Anyway, I ask your advice once again. Should I go with two SSD12s or one BTL15 powered off of a 1500d running at 1 ohm? If built in their ideal boxes, which would get louder, or would it matter? What would be the pros/cons of either? Mahalo, Trevor

Guys I have purchased some ssd 15's from a guy and was wondering if I could send them in to get the bp power upgrade or if if that is something that has to be done at the time of the first build

ok someone told me before that if they were standard 3" coils then they could be reconed. well i got bored and ripped on of my blown T1's apart. outside of the coil is 3.204"-3.244" and the inside of the coil is 3.020"-3.051". bent a lil bit, maybe from removing it. how much would it cost to recone? how much power would it be able to handle? would i just be better off buying ssd's? thanks. p.s.- any more dimensions needed ill see what i can do, its kinda hard to get into the basket with a 6" dial caliper . but ill see what i can do if ya need me to. the gap in the motor is approx. .145"

Hey I going to be getting 2 Fi BTLs fully loaded with the daily instead of SPL option, should I get the Rockford Fosgate 4000-1BD or Sundown 3500D?

DAMNIT, well i heard a lilttle noise coming from my speaker today, hadnt played it in about a week, but anyway, i pulled it out the box to find that i have 2 holes in the spiders from tinsel leads, and numerous rips, guessing its from playing below tuning. i need to know how much a recone is scott, i dont know wether i will or just sell it, looking to get a new truck and there wont be room for a BTL 15, its loaded by the way, What to do??????/

Is it safe to run a single fully loaded 18'' BL on a Rockford T2000 @ 1ohm?

I ordered 2 15" fi btl subs I also already have 2 rf t40001bd amps.. I was curious if everyone thinks I should just use one of the amps for both subs (each amp would have its own sub) or if 1 amp should be enough for both subs.. Any help is much appreciated

ok so i have built alot of enclosures in my day but it has been about 4 years or so I have a mx15 in my truck right now with a 6" round port and its tuned to 32 hz sounds great i am super happy with it ok now onto the project I am helping a friend design a box for his car and a wedge style box is optimal to save the limited space that he has I will be using a BL12 and we will be making a ported box for it but the standard slot port wont work well for his application so we are opting towards a round port now here is where the issue arises I am unsure what size port i should be running single 6" or single 4" or possibly something else the enclosure we r shooting for is a f…

that is 1.5 cu.ft after displacement at 35 hz,has anyone here done this? if so,how did it do ?

So i just ordered my 15" BL sub, and im getting it soon and cant wait, but im kind of stuck on what amp to run it off. I was looking at the Kicker ZX 1500 amp, using all Monster cables to power it. however, before i spend my money on this amp, i want to be sure that it will be the right amp? is there any other amp that could be better for me to get around the same price as the kicker amp? i rlly want my sub to pound, but sound good at the same time. thanks alot to anyone who helps me out

I want to make sure I'm not going to burn up my coil on my SSD. I bought my sub 4+ years ago (I don't remember exactly), copper coil option only. Back then they were rated at 800rms. I have it wired down to 1 ohm, so it should be receiving 1200 watts+ since I have read lots of times that Sundown amps usually do over rated power. I set my gains using an SMD DD-1. I know these are frowned upon by a lot of people as a waste of money, but I didn't buy it and just borrowed it from someone who did. It helps to set gains so there's no distortion, so I'm assuming nothing is clipping. That's just my assumption though. I set up my headunit, sub amp and mains amp all with the DD…

Hi all, I was curious, has the topic ever come up on here about running one of the Fi dual voice coil subs with only one voice coil connected? I was reading through a forum post on the12volt.com about how it should not damage a subwoofer if the loss of heat dissipation is accounted for by running at a lower power level. Obviously it is better to run both coils whenever possible, but it might be useful to run single coil if someone were stuck in a non-ideal amp setup. the12volt thread What % of RMS power would be acceptable to send to a dvc sub in single coil configuration? Thanks

hi im a proud Fi owner and was planning on upgrading some time in the near future.. i have a BL right now and would like to upgrade to a BTL... i had a custom enclosure made just for my BL made to all Fi's specs... i was wondering would it be possible to reuse this box for a BTL?
