It will be a while before I can afford a charger, $90 is a good way toward the $150 brackets I need for the 2nd alt. Rear 1 is now 11.95, rear 2 11.75, front 12.00VSo keep the rears disconnected until I can get a charger?

Alright all you whiners and complainers, you guys said you were gonna this and you were gonna that. It looks like they went up about 20 bucks but they are "new and improved" so links to your build logs, post up some pics and vids here too please.

having some fun while waiting for the 1st set to cure didnt wait long enough but it will work... or will it?

So here is the business about smashed and cooked coils. I have gotten so much hate over the last 2 years about having to recone IB3s. First off, for the last 5 years I have only blown 7 subs. To the home theater guys that never do, that may be retarded. But to the SPL guys, they do more than that in 1 show. It's all relative. However, for a guy infamousely using IB subs in the "wrong" application off 6 times the rated power, are you guys serious? If a subwoofer is made for an infinite baffle, it is made to handle very little power... its not supposed to be loaded, it moves freely. I cram them in undersized boxes and port them milking them for all they are worth. So if these things were to die, they should die from burnt coils, too much power. I gave them 6 times their rated power yet I never once cooked a coil! Second, I am a poor boy. White trash. Red neck. I havent had the luxury of lots of money over a long period of time. I havent gotten to purchase subwoofer after subwoofer, amp after amp, try a new box after another box. I sat at the sidelines and drooled. Watched vids and stared at pics, the reason I am a vid and pic whore now. I got lucky, I got a pile of money... not a huge pile BTW... and I got 1 shot to stretch it out and get ONE try at a good home theater and a good daily driver. My home theater is famous. My home theater puts up numbers that others took 10 times or more money to get the same numbers. I had to. No experimenting, no years of adding, tweaking, learning, and upgrading. I had to plan with no experience really...no experience with anything on these levels anyway. I am going to pick a person that I like as an example. Twistedchild420. This is all respect, all love, for twisted. NO hate. Everyone else likes the guy too. He has had a "J L doubleyou seven for the cost of four hundered and...." most of us loved that vid. The guy has had giant expensive 8s, Digital Designs 12's or 15's, Incriminator Audio DP 21", old school rockfords. RD 18's. DC's? IDK if those were his. 8kW prototype amps no one can get their hands on. SAZ 2kW amps. SAZ-3500D. Stetsom amps. RD.I think he's had many other giant expensive amps. Hes had just as many different enclosures as he has had subs and amps. He has the money to buy new things and try them, try something new. Experiment. I have not. My subs were $199/ea. I had 4 IB3 18's in my van and 2 IB3 18's in the home theater. $199 plus $18 shipping per sub. Twisted cooked a $900 LMS ULTRA 5400 that was prolly $100 for shipping off a SAZ-2000D. Those amps are what, $900ish? Top of the line. That LMS ULTRA is rated 4000 RMS IIRC. So the guy blew up a $1000 subwoofer with a $900 amp rated for 1/2 the LMS's power? But I have $340 Audiopipe amps doing SIX times the rated power of $199 IB3s, get 148dB at 25Hz.... not many people on the plantet get to hit 148dB at 25Hz, those that do have $1000 subs, $1000 amps, $500 batteries.... and 2-24 of those $1000 subs, 2-12 of those $1000 amps, and 10-20 of those $500 batteries...along with 4-7 alternators. They build to be loud, to compete, not daily drive off a budget. LMS ULTRA 5400 after being reconed by PSI Twisted blowing up an RD Heavyweigh designed to take gobbs of power IDK if this is Twisteds, but here they purposely blow a DC lvl6 thats MADE to take gobbs of power and burp

I have had my cut out cones sitting outside since last year, out in the rain snow and sun, and the only thing that has happened to them is the cones on a few have turned white. The paper cones are still solid, foam surrounds are all good, glue holding them turned white but not loose one bit. The coils havent rusted, the coil glue hasnt let loose... they are just the same as when I cut them off other than bleeched. I have been impressed every time I look at them, so the other day I was having fun and displayed them on my porch. It stormed hard last night so I went out into the dumping rain and snapped some pics. I think drivers have come a long way over the years, as everything else does in life. Years ago foam surrounds were eaten up by the sun's UV rays. Cones were as well, along with moisture. But it seems now they are indestructable with the exception of pure abuse... like 6 times power rating smashing coils. I'd like to note that every single coil in these snapshots were smashed...not one coil was scortched or burnt. OK, one coil was scortched, but thats because I smashed the coil then tried to see how long it could handle pure sine waves before melting. It never melted and I became worried the amp would fail instead. I have been running these IB3s off 3kW amps for over 2 years and never cooked a coil, the new line has improved thermal cooling with 3 smaller pole vents vs 1 large one, yet the power rating is still 550watts: mechanical power handling in infinite baffle down to 20Hz. But who only goes to 20Hz these days? I do 110dB from 5Hz up The image of the 8 failed Maelstrom-Xs was inapropriate, so I was asked to change it. I didnt want anyone to think I was being cute or clever by now doing a pic of destroyed IB3s. That is not the case nor was my use of the Maelstroms a sign of disrespect. I found the Maelstrom image a powerful one, very moving. An icon driver, one of the best ever made, one that many of us have stared at and drooled over for years just wishing one day we could have just one...and here were 8 just sitting there. I couldn't help but feel sick every time I looked at it, but I couldnt click away. So this is a silly thread that can just be removed, but I have it up to simply say I mean no disrespect, and maybe spark some conversation on technology and its advances.

Needed to do recones, blew a dustcap... it's funny the things the kiddies pick to tell me why I suck so bad that others do as well. It's not that you got the same SPL as me 5Hz below your tuning with 1/2 the cone area... it's that Ive had to do a few recones though I run 4 times the power, though you had to do a recone too :-P I'm just gonna complain some more, if you don't mind. The fact you still have my attention just means I am still impressed man!

Kick ass!~ I dont need a vid to prove it, I was more concerned with it being at 25Hz not 27Hz.... you basically did it then, man.... you did what I do with double the cone area. I really should sell all my shit lol... I am in the wrong hobby, at least for auto... my HT is another story I am very impressed, and disapointed in myself!

I managed a 148.2 at 25Hz a year ago in a vehicle that was NOT designed for competition, let alone SPL. I simply wanted a vehicle that could get pretty loud, pretty low, and yet still sound very clear. Out of curiosity I went and got metered to see how loud it was below 30Hz. When I did so I got bombarded with "well this guy with 24 15's in 4th order got a 161 @ 25Hz" and "well this guy got a 154 with just 2 10's at 25Hz". Later some guy, who despite being from this forum was very polite and nice, comented on some of my posts. He was installing 2 18's and tuning around 30Hz IIRC. So I joked and said I'd give him my other alternator if he could beat my 148 @ 25Hz. He told me the other day he got a 156 somthing at 27Hz.... which is a ways off from 25Hz, but even if he lost 6dB going down 2Hz he'd still have beat it I'd guess..... assuming it was on a TermLab. So I'd like videos, proof, of people besting a 148 @ 25Hz or lower. Not 26Hz or 30Hz.... cuz that isn't the same. Must be TermLab, not the neat digital display Xzibit used on Pimp My Ride for the 22" Jackhammer. I'd like to see TeamRamRod's build log and videos of him getting 156.7 at 27Hz because thats impressive for any setup, let alone only a pair of 18s.

You didnt seal that window off? I caulked mine shut then filled them with 120-140 cans of Great Stuff, the big 24oz ers. I bought 5 24 packs then started buying 1 at a time till finished. learned my lesson though, next time I'll only do 5 cans at a time and let them cure 48hrs before the next set. Did you get TermLabed? I'm still very impressed man, you did great work. Kickin my ass with 1/2 the cone area.

Little vid i made of REW and a couple sweeps, a lot of people that subscribe to my vids have no idea what REW is, where I get my numbers or graphs. 110dB from 5Hz up REW Room Eq Wizard.AVI

Id sure like to see what Brian's FR looks like with 8 sealed up IB.... heres what Im doing with some more bracing and sealing up to go yet: My title "sealed up" is misleading, I am ported 1000 cubic feet tuned to 5Hz, I closed the entry way door to "seal up" the listening room a little better adding quite a bit in the single digits. I need to brace the ceiling more and seal up both the manifold door as air leaks around it as well as the entry way door.

just ran another sweep with the entry way door sealed up. So much for retuning higer, work on more bracing and more sealing up and I should be golden to 5Hz.

How does REW know how far down it can EQ? How can I get that spike at 5Hz, or at least make it flat to 5Hz?

Audyssey set all speakers to negative something, the sub was -12dB. I swept it again with -9dB then -6dB and still have headroom, but not much, so i will leave them at -6dB

I started to remove several filters as there was too much 5Hz-10Hz and everything else was dead, as I removed the 2nd 40Hz the buzz came back, and only on 1 side. Something is wrong so I took the BFD back out. Ran Audyssey for the 1st time, IDK who's system this is...but its totally different...instantly. Here's sweeps starting at -35dB in 5dB increments to -20dB and I still have a TON of headroom.

Filter 1: 40Hz -48dB Q 60 Filter 2: 20Hz +16dB Q 120 Filter 3: 20Hz +16dB Q 120 Filter 4: 20Hz +16dB Q 120 Filter 5: 20Hz -16dB Q 60 Filter 6: 20Hz +16dB Q 120 Filter 7: 20Hz -16dB Q 60 Filter 8: 20Hz +16dB Q 120 Filter 9: 20Hz -16dB Q 60 Filter 10: 20Hz -16dB Q 60 Filter 11: 40Hz -48dB Q 60 1st problem: as I was adding the last 2 filters I noticed rumbling got loud when I added dB, then i realized 1 side was doing it but not the other, before I saved it, though both engine lights are on. When I did the following cut it fixed it...but that doesnt mean they became symetric again. So I did sine waves at 6.5Hz, 10Hz, and 16Hz to make sure both sets of subs have the same excursion. They do. However, at 6.5Hz when I get it loud enough to get amplifier noise, it was on the same side that suffered rumbling. Anyway.... the 2nd -48dB cut at 40Hz killed it: but then the last filter, 12, boost 16dB at 20Hz Q of 120 fixed it and I am happy for now. Final sweep

I have 4 IB3s in the HT and 4 IB3s in the van (ok, not anymore, airspace was 1/2ed and tuning almpst doubled so now I have 1803s) I only spent $1760 for 8 IB3 18's shipped... $199/ea plus $20 shipping each. 8 LMS ULTRA 5400s at $900 plus $100 shipping would be $8000. If I could get 8 ULTRA 5400s for 2K I'd be running them for sure

What are some of the 18" drivers with the lowest Le? Does it even matter?

Look pretty sick Scott, I didnt even notice but Brandy did. Sure wish i got replies about recones for the 1803s....

I have custom dual 4 ohm coils run series/parallel 2 IB3 18's per EP4000 bridged 4 ohm. You could run 2 single 2 ohm IB3 18s off an EP4000 either stereo 2 ohm or bridged 4 ohm. Be careful, you have a lot more power than you need, you will never ever cook a coil with it (I ran 10Hz full excursion at tuning for 10 minutes and the amp got a touch warm, barely at all, but the subs stayed cool) but you could run into over excursions quickly without warning as they soiund just as good near full excursion as they do with no visible excursion at all. The new ones look sick, I didnt even notice but my girlfriend did.

Thats a vid I would love to see! For proof? well sure... but no, cuz thats what i LIKE. 192dB at 100Hz off 4 Adire Audio Extremis 6 4s sealed with 1700 RMS

everyone is misundferstanding what I am getting at, and that is fine, I am always misunderstood. I believe your pics. I also knew ahead of time that those meters are supposed to be good to .5dB or whatever of the TermLab. But the fact is, I would like to see it and see it at 25Hz and see it with a TermLab. I didnt record mine just for proof, I did it because it is what I myself like to see. People get pissed at me for doin sub excursion vid after sub excursion vid. Well before I could afford subs, I sat and watched sub excursion vids all day. I enjoyed it. I couldnt get enough of it. Now I make it for the other gu out there that took my place and I hope someday he gets to make some badass vids for the guy that replaces him. Also, I am new to REW and mics, but I have been into them for a couple of months now since someone sent me a free mic to see what my towers were doing. Since then I now click on threads about mics, I learn about them, and I see side by side sweeps of different mics and see that you cant compare systems with different mics. I dont care, Ill say it again... youre getting 156dB at 27Hz with 1 or 2 18s and that is INSANE! Period. So anyone can say whatever they want, I dont care, I gave you my props, sorry but Im not giving you my alt though even if you do a 161 at 25Hz with a TermLab and theres a link to an official record.... that wasnt the point! I am impressed, I tried my best, my idea got me a 148, you tried...you kicked my ass... I salut you! Sincerely! Having said all of that, I pulled a KW and did what I do... try to make the cool ones laugh and the retards that think they are smart talk shit.... without further ado: getting REW set up still setting up and dude walks up trippin nuts, mic wasnt set properly yet ratshack meter

Thanks man, I lost it for a second there.... glad you put it in a much more mature way than I did

Im not out to prove shit to anyway. i was there, I dont care what you think, I made a joke to the guy and said if he can beat me at 25Hz with just 2 subs Id give him my alt.... looks like he can do it, I was wrong. I dont really care that much.... but I have a radio shack meter and an Audyssey meter I bet I could hit 160dB at 10Hz with them.... so i am simply stating I agree with him he can prolly do it, but Id sure love to see a video of him doing it at 25Hz, not 27Hz, and it being TermLabbed not something else.

mind you 1 of 4 amps may have been blown at this time, so 3 subs were getting canceled by the 4th as well as the port not loading to reduce excursion or adding output.... Ill get TLed again now that I have the amp replaced after I get my other alt installed (if I get to keep my other alt LOL :-P ) 147.7 23Hz 147.9 24Hz 148.2 25Hz and 26Hz floor.AVI 132.5 15Hz 136.7 17Hz 140.3 18Hz 142.5 19Hz 143.8 20Hz 144.9 21Hz 145.7 22Hz.AVI 147.7 23Hz hair trick unintentional.AVI put on 148.2.AVI
