A good friend of mine just recently traded his 2 12s for a Btl n2 15 and is now looking to build a box. Being the guy he is, he likes the lows. This sub may not be the most applicable for his needs but he's hoping for the best. He likes loud, and he likes low. We were both thinking about a box that is roughly around 4 cu ft using 3/4 mdf. We were also thinking on possibly doing an aero port(s) design. Although a slot port is still an option. If it helps to know, the box will be going into a 1991 Jeep Cherokee. Also it will powered by a Hifonixs Brutus brx2400. He and I would very much appreciate if anyone has any designs for this type of application and or any re…

So I'm in need of a box for my Bl 15 in my scion tc.. I was going to get one built and shipped to me but it will take too long. Went to my local shop today, and they had one box for a 15". He said it was around 3.2 cubes which i guess is ok. Asked him what its tuned to and he didnt have a clue, said around 44 or something, which i would think is too high for the BL as i was shooting for 33hz. The box is carpeted, and higher up on the end where the sub goes in. Has two small ports in the sides. Price is $180. What im wondering is if the tuning really matters, and if it will sound like shit if i use this box?

I'm getting away from a ported box with my X 10" and going small sealed like .6ft^3. So what kind of power would get it rocking pretty good. I'm thinking around 300 but currently have 160 on it and love it. I want more sq and not so loud as ported. I love the sub and don't want a different one just different sound.

I plan on running 8 ssd 10's. 2 per box at 500 watts rms each. Each box will be 3 cubes before displacement tuned to 33hz. I plan on running 1 4" aero port per 2 subs. Do you think I will get port noise with that size port on only 500 watts? Thanks, I hope that wasn't too confusing.

want to know what fi soft parts to beef up my aa12" havocs .will the motor support an spl optiion or would it be better daily, or in between. .......... FRANKIN HAVOCS ON THE WAY????????!!!P.S. CAN YOU GUYS HELP ME!!!!!!

how much max RMS watts can a 18" fully loaded BTL N2 handle ?? i was wondering if i can run a 2400 watt RMS hifonics amp to it ?? also will a 6 cubic feet box ported to 35 hz sound good ??

building a normal box but using two layers of 3/4 mdf all around, which way would be the strongest? i know the first would be the easiest with less cutting, but would number 2 be so much stronger that i should definetly go with that method? Number 1 Number 2 any opinions are appreciated!

Whaaat happened? you guys just ruined my next setup :(:( will there be any 15 bls coming?

ive been using subwoofertools.com to help me figure out what my dimensions are going to be, but i have a problem. My max dims are 36x24x12, which correct me if im wrong is 6 cubes. but i cant ever get the depth to be close enough to 12 inches for it to work. id like the box to be about 4.5 cubes at around 34 hz. the closest design ive come to is 4^3 at 34hz, but that is with the xmax part at 16... im really frustrated right now.

How would i wire this my friend told me to get the dual 1 ohm and he knows what he's talkin about but the amp is rated at 1000 rms @ 2 ohms. Can someone tell me how to wire this

I ordered a re cone kit for a 15" RE SE 12 spoke basket/motor. I opted for the double spider option, internal leads, etc fully loaded. About how much power can this sub now handle? I did not see any specifications on the re cone page. Thanks for help in advance

Can we get a section pinned to this forum of the options and what they do with the sp4 and also enclosure recommendations

I was wangin my ssd the other day and it was wangin hard, loud just like fi should then i turned it off went inside and about 2 or so hours later i went back out there was about to leave and the sub or amp just didnt pound like it did before. It just wasnt as loud and didnt vibrate my whole car like it did before. I think it might be the amp, but im not quite sure. I figure it might be a connection problem or somethin, but i checked all that and no problems. Thanks Mike

Im looking at getting 2 subwoofers. Trying to decide between the SSD10, SSD12, Q10, or Q12. This will be a sealed with about .9 to 1.2 of airspace-haven't decided, depends on subs. Between the SSD and the Q which sounds better sealed/louder in sealed. What options would be best. I have read the descriptions of the different wires and still dont know what peaking is meant to be. -what effects will the flatwind coil or copper have on the power handling and sound quality and loudness. Peaking? better for sealed? -Is the BP option worth it in sealed. Will any of the options help reduce the subs heat in the seal enclosure. The subs will be sharing the power of a kicker zx…

Hi guys, I used the cut sheets for the fi btl 12 inch before. Was wondering if anyone has any cutsheet for 15" sp4 in sealed enclosure. Just for daily setup powered of a saz 2500d.

How much power are you guys running to your SSD's, optioned out, or not.

i emailed Fi SIX months ago askin about gettin a recone, and well im still waitin for a reply. i think i sent a email to nick, but cant remember. who else can i get ahold of to get a recone?

with a box at 27x21x27 what size port would i need to run a 18"btl at 2000 watts? this is just the available area for the box. with displacement it puts the box at 7.13ft^3. and i am using 3/4 mdf. or would it be better to run both btl's in the same enclosure and port it. if so the box would change to 27x42x27. what port length would be needed to run it at 32hz?

ive had a fi x 12 for a while now in a standard ported box i built. i want to spice it up a little by building a 4th order bandpass. Problem is i dont know the calculations for it. If someone could give me a hand in this it would be much appreciated. iw ould like to tune it to 35. if not that than 40.

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

I am running (2) of the 12SSD's in a ported box at right about 4 cu. ft. net and its tuned to about 32 hz. power is rated Zapco 1000W if I can get another cu. ft. What can i expect in the characteristic of the box? More efficent? more boomy? I do not want to make it sloppy, it's already ported which is a trade off for me to begin with. Or I might consider the max sized sealed box. How would you compair that to my existing ported box? thanks

Ok, I have an older BTL18 that was originally a D1 (written on the pole) and its in need of a recone. The owner got ahold of a D2 BTL18 kit, and I got the basket cleaned up and ready. It an older non-woven tinsel kit. But, I have it a snag...the D2 coils OD is noticeably larger than the D1. I have the kit shimmed and in the gap, but is this kit going to work??? Or will the coil hit the top plate when playing? Its a tight fit, but does have some space. Anyone make the D1 to D2 switch? Please reply soon...the owner is in need of a sub.

Does anyone have any clue where I can obtain so rough plans or designs on making pacman boxes for my 4 15" BTL's??? I have been searching but coming up with the stupid pac man game somehow..

Since my second Q is getting here tomorrow, I thought why dont I start working on the box like tomorrow or Saturday since I have nothing better to do on those days.. So I was hoping that there is someone around here that is an expert at box designs and cutout measurements could help me on making a design and measurements then I'll build it... The box is going to be for 2 15 inch Fi Q's.. Ported.. I would like the subs firing upwards and port firing towards the hatch.. Also, I want it to be tuned at 32hz.. It will be going in my explorer.. so the max dimensions I got: Height: 16 1/2 inches Length: 41 1/2 inches Width: This wont matter, I got plenty of room, but would li…
