Subwoofers / Speakers

I currently have two Obsidian Audio OA12 V2's running off of 2 Audiopipe APSM1500's strapped @ 1 ohm. I used to own a Fi BTL 12" UFO motor sub before this system but on less power. The guy that currently has my old BTL is wanting to trade straight up for my two Obsidians. I think my Obsidian setups is a bit louder than the BTL was, but I really liked the way the BTL sounded, and it's able to handle the power I'm currently running better than the OA's. I'm considering the trade, but I'm looking for other opinions on whether or not this would be a good trade or not.

been having a hell of a time finding them, searched CA.com and carstereo.org where re's forum used to be. seems its dead over there, and figured someone here may have them handy.

Whats the price for 2 lvl4 18"s with level 5 coils? dual2's

I can't seem to find another place to buy a Cerwin Vega Vmax 12.2 anywhere but a local shop and from sonicelectronix. Anyone know of where i could pick one up for a decent price? Sonicelectronix wants $189, plus $31 in shipping fees. I am looking for the newest model, which is this one if anyone knows where to get one it would be appreciated. Thanks!

just ordered a kx550.3 and i need some suggestions on a sub. if the maw's were still in production , id snag one up , but i decided to downsize too late. so i need some suggestions for a 12" that will work well in both sealed and ported enclosures being fed 350-400wrms @ 2 ohm that will get decently loud and not sound like poop. budget is around $100 but ill spend a bit more if i have to get something quality. i was looking at the RE SR , but i really couldnt find enough reviews on them. thanks in advance.

hey there.. i have made some mistakes on my box and now i am attempting to fix it. i need to know the displacement of an aq hdc3 15. side note: my box is unintentionally tuned at 30hz.. re-tuning will be at about 38hz.. will i hear a noticeable difference in audible sound after the re-tune??

I have 2 MJ18ms and yesterday i noticed it wasnt geting low as it used too, I noticed it yesterday night around 1 am and it was freezing cold it was ice on my roof, and I had to tug at the door to open it I played songs that would shake the entire car and it just wont do it. I had to put sub out to 15 (max on my alpine) to get it to do anything like it used to I normally have it at 8 whats going on Is my amp dying or what? cant be my ears, becuse I can feel my system

Im planning to do a wall in my car but my wife says I have to wait until we have another car (we have kids.) In the meantime I have dimensions of 33Dx31Wx16H. With .75 MDF that leaves 7.79783 cubes total. I want to run one Xcon 18 but I dont know what the mounting depth is. Obvioussly Ill be mounting it sub up so my D will become 16". I assume 16" is deep enough but? After port and sub displacement I should have about 7 cubes and want to tune to 32hz. is 7 cubes at 32HZ. too much for 1 Xcon18?

my friend is looking to build a box and install a sub under the back seat. we don't have the dimensions of our space but we were wondering what a good sub would be that is 5" or less deep. were thinking one 10" or two 8" subs in a sealed box. or one 8" in a ported box. any recommendations would be very appreciated. we will be able to fit a 1cuft box according to the stealth box that is sold on crutchfield.

I've got two Havoc 15's for my extended cab ford ranger. I want to build a box for them but I'm debating between ported and sealed. I know ported can sound good, but there are certain advantages a sealed box will always have. (such as transients) I listen to primarily rock music. I have about 8cu ft available, and two 15s. How should I go about designing or choosing a box?

so what is the difference between the fi ssd and fi q. i am looking for a good daily driver and heard good things about both subwoofers.

Does anyone have the full t/s parameters for the XS-15dv.2? thanks.

So i have a friend giving me 4 RF 12" punches tomorrow in a big sealed box. I'm wanting to put it in my car just to see how it sounds. I'm pretty sure the punches are 4 ohm DVCs. Anyone have a good diagram on how I should wire these for minimal impedance? It would be much appreciated. Also, if anyone is curious on how they perform, I will shoot a video and post it on here.

if you take a fully loaded btl D1 coils and wire up one autotek mean machine 1500d to each coil would it put each amp at 1 ohms since its a 1 ohm coil?

hey everybody I came across a great deal on 2 Cerwin Vega Stroker Pros 15s and was wondering if they're any good? I was looking at the specs for a box and seems to be significantly smaller than the size of the BTL...anybody have any input?? thanks, Andrew

Just looking for a sub that will perform well in a sealed enclosure, and take6-800 rms. willing to spend around 200,shipped. everything is pointing me towards it, but i want to double check before i pull the trigger. Thanks in advance. Dave

Is it true, that it's not good the tune a box lower than the subs Fs? I always thought that you can tune a box lower than the Sub Fs, what's true about this and what happen if you tune it lower than a subs Fs? anyways, thanks.

well i still havnt decided on what i want to get in my truck. i drive a 03 toyota tundra access cab and will be removing the back seat for the box. i plan on doing the big 3 and getting a kinetic battery to help the electrical. as far as music, i listen to everything so i want the sub to sound well and i want it to be loud. something that can play all ranges of bass and be loud, not only certain spots. sorry if i dont make sense i dont know how to word what im thinking. i was thinking of a single 15" and saw the ssa 15" xcon. would this be what i am looking for?

AQ recommends what seems to be a pretty high tuning of 38hz. does anybody with these subs tell me if they can still dig pretty deep notes (i listen mostly to rap, but i also watch DVD's in my car) thanks

I am a new owner of a SI D2 Mag 12" Version 2 subwoofer. I need help with a box. This sub will play 65Hz and down and will be powered by a US Amps 900Watt at 12 volts amp. My car runs at 14.6 Volts. The rest of my system will be this. CDT ES520's in the kicks 150 Watts. CDT EF8's for midbass on the doors 300 Watts. The ES's will play 250 Hz and up. The EF8's will play 65Hz to 250 Hz. The SI sub will play 65 and down. Everything will be powered by US Amps. I am a SQ guy, so at first I would say I am looking for a SQ sub box design. However I have to ask , if I have 8's up front doing the midbass, and the SI sub is only doing 65Hz and down, will SQ even matter? …

I've been waiting to order the magnums si but dont know if they are even in stock yet. Is there a waiting list?

Dont wanna email Nick, and Im sure some other people are wondering as well. Any good news on the subs? Anything to keep us goin on Hows production coming?

<edited>

what the hell are you gonna put that thing in? And it comes in an 18
