Hey guys, as the topic says I have a problem with a SSD 12... the spider feels very weak in a spot like there is a crack under the top one. So my question is will it be fine to run like that? (i don't know how long its been that way but it worked fine till the day I took it out) or do I need a recone so it doesn't get any worse? Thanks

how much airspace would you guys reccomend for 4 x Q 18's in a sealed wall?

Well my 1 18in fi bl mag cracked. Dont ask me how lets just say that i am very sad that this happen. And another bad thing that happen is one of the voice coils went bad in it to. I took one of the subs out of the box cuz i heard alot of buzzing. Then saw that the top magnet of the motor was split in half. I dont know why this would happen but it went from me bumpin super hard to only bumping a little with one sub. So if anyone has a BL motor please let me know or give me some info on how i can get it replaced thanks.

My fully loaded BL 15" came in today so started to design my box. I want to use an 8" aeroport and wasn't sure if it has enough port area. Box is 5.5 ft.3, 8"x17.5" flared aero tuned to 33hz and going to be powered by a DD M3a at .5ohm. Will the 8" aero suffice or will it choke the sub?

I ordered recones for Konaki motors, if you can remember, I have the thread up in the General Fi section, anyway, I was wondering what type of spiders and coils you used in the recones construction. It looked to me like 3 spiders were used and the coils were copper flatwind. Also would like to find out what you guys would estimate the power handling (rms) of the sub would be with the soft parts you sent me. They are seeing probably 1200 watts each, which I am sure they can handle fine, I do not plan on upgrading my amp EVER, but I am wondering just out of curiosity what the rms of these things would be.

specs on 09 fi ssd 18

So, I ordered 2 SSD 12's last week, (currently have 2 Pioneer 307's in a ported box I made a while back) I was just wondering how to make a decent ported box for the new subs. Car is a 97 eclipse, and the dimensions I got were (15h x 36w x 20d inches) I might be able to go .5in more on the height and depth. Would the height of the port be 13.5in? What should the length and width be? I'm using BassBox 6 Pro but when I put in the info for the port it adds to the total volume of the enclosure which for some reason makes me think it is going to come out wrong when I build it. Any help will be appreciated. I'll be powering them with a RF P1200.2 Thanks.

i currently ordered a btl 18 with 2100w amp and i also got a new high output alternator and kinetic HC 1800 high current power cell to replace my standad battery and was wondering if i need another battery?? just confused because do i need one under my hood and one next to the amp or just one? and if i need two can i get one smaller one for the back?

Hey guys, first post! Haha. Well, I recently just received my 15" BTL in the mail. I was looking and it and noticed that there were no screw holes for mounting the sub to your box. So how do you mount it? Another question I had was, is there a special way that I should be breakin in the sub? I didn't know if there was a good way to do it. Thanks guys and appreciate all the feedback.

sealed up at the kicks i hit a 144.8 with my single 12" BL. at the dash sealed i got a 144.3 the meter was an audio control. and i lost 1 db when i opened the window. song i used was airforces and hypnotize. they both did about the same number. Basically what i want to know is if this is a good number for a single twelve trunked car? could i get it higher by using a 50 hz test tone or somthing?

can anybody help me with box design? i was just gonna make a box similar to the one i have in my escape for the ssd 12's but i kinda want something a little better. i listen to every type of music from bass music to jazz to rock. so the box would have to be versitile. the twelves only have copper coil option. i need help because the space is limited. i have a huge trunk but for some reason benz decided that was also a good place for the gas tank and spare. i am thinking that the port(s) should face up through the space in the rear deck that will be cutout. i have two sets of max measurements because one way the box would have to partially cover my amp and the other way it…

i want to get a 15" BTL and put it in a 1999 dodge stratus. i cant decide if i want a ported box with the BTL firing at a 45 degree angle towards the trunk and have the port firing towards the seats (i currently leave my back seat down, it is MUCH louder). OR go with a sealed box with the BTL firing towards the seats with my back seat down. i was thinking a Hifonics Brutus 2406 for it, which is 2,400 watts RMS at 1 ohm. i would get it fully loaded. PLEASE MAKE ALL THE RECOMMENDATIONS YOU WISH! another thing is the new BTL's, there is no triple stack magnet!?!?!?!?!?!? it is just a single magnet, why would they to that???

haven't been on here in a long time. i'm trying to run two of these, but i lonly have 2 cubes after displacement for each. i already built the box and i'm waiting on recones. it's tuned to about 37. just wondering if anyone tried btl 12's in the same size box and what you thought of it? oh btw amps are 2 t20001bd's. one to each woofer, dual 2 ohm woofers.

I have 2 mono amplifiers of the same kind and I have a dual 2 ohm sub. Is it possible to put each voice coil to each amp without hurting sub?

I have an ssd 10 under the back seat of my nissan titan and im havin problems with it hitting the grill i have on the box when it pounds. Ive been adding wood to create more space between the sub and the grill but i was wondering if there are any other techniques i could try. Any help would be appreciated.

If anyone can help me, it would be greatly appreciated. I had somebody build me a box for my (2) 15" Q's but I think the Tuning is off. Can you tell me the Size and tuning of it? here are the dimensions. The box is: 35"x25"x25" The port is: 29"x23.5"x5.5" Thank you!

the actual diameter of the BL 18? need to see how im going to have to design my box

Both setups will be run off of a Sundown Audio 2000D amp. I only have a space of 1.1 cuft per chamber to work with. I mostly listen to rap and want these subs to be able to lit the lows well.

Ive got a Kicker KX600.1 that I'd like to pair with a 10" SSD to avoid purchasing another amp. The amp specs are RMS Power at 2 Ohms 600 W x 1 RMS Power at 4 Ohms 300 W x 1 Opinions on this vs getting something for the 1000rms rating of the 10" SSD

I'm too lazy to A. Look down this page a bit to see the other 8 questions asking the EXACT SAME THING. & B. Use the search function. & C. Go read the stickys at the top of the page that list recommended enclosures for all of Fi's subs. ...so I figured I'd pollute the board some more with my "problem" that really isn't a problem, and doesn't need anymore discussion. Thank you.

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.

so, i got an enclosure built for my 12" BTL (single slug motor) but the magnet refuses to fit into the cutout. i was wondering what the cutout diameter would make it fit. i can't trim the cutout because its only enough for the cutout itself since the box is 14"H with only .25" clearance on the top and bottom.

i recently ordered a fi q 10 and it came in today i hooked it up to my RF p6002 wired 4 ohms and when ever i turn the volume up i hear a awful rattling noise it sounds like it is coming from under the dust cap. i read through the forum and found another person that had the same problem and i think it said his dust cap broke the glue loose or something. if this is the problem how do i fix it? and what do i need to do to fix it? again this is a brand new sub and has never been used before. does fi even test the subs before sending them out?

ideally, what would be a good power range for the ib3 12 inch sub?
