I'd be really careful, especially using a ported enclosure. From my experience with Eclipse subs, it doesn't take much to blow them.

 

eclipse subs were really designed for small sealed boxes.. im not at all saying they cant be used any other way, but there a very clean sub. and sealed boxes (built right of course) are cleaner. I would be very carefull putting that much power to them.. I get huge headaches putting about 700ish to my 2 because its pretty rediculous.. it was 138 db, with more in it.. i forgot to up the gain (it was on 4) and my door speakers were starting to distort, not the subs.

 

Edited for stupidity
Eclipse subs have some of the stiffests motor structures available which makes them wonderful candidates for a vented box.

I do doubt that he's really putting 1000wrms to them though.

 

no, actually he did get 138 ;P

 

really?! I missed that.

 

Well, he's running a jl 1000/1.....so I would assume it's a true 1000w rms.

 

All wattage is based on volume control - even at full gain the 1000/1's regulated output wouldnt put 1000w to the sub until the mids were to a close to unbearable volume. And because its regulated it wont peak much higher than that. How often do you really drive around at full volume(unless you are an asshat who likes annoying people)

And at full volume, even rap music doesnt usually (there are some that do) produce continous bass output so there would be plenty of time for thermals. People usually dont think about that when they are purchasing equipment. For dailey driving, a person with and 92db/m speakers would rarely if ever use more than 40 or 50 watts totall for all their midrange speakers and 100-200 to drive each woofer...


A true 750wrms speaker will without a doubt be able to handle 1000w music power reliably - maybe even more. Now if you throw sine waves on it thats a diff story.

 

dude every box i hear you talk about is vented or ported, and saying how much better it is.. and time and time again i see you proved wrong. I did hit 138, I can hit more.. do i need to prove anything to any of you?? no.. are eclipse subs not made to be cleaner then loud?? be honest with yourself here..well the eclipse rep i talked to would beg to differ.. according to him what im saying is right..

 

... you cant prove a fact wrong. ported boxes are louder.

And when properly tuned and driven they are just as clean. But yeah, I'd love to see your new in box... and still in box system hit louder than 140. go for it.

 

No shit. But I'm not talking theoretically. What's next, are you going to explain to me how the amp isn't putting out 1000w rms when the car is off either? My point is that the jl 1000/1 puts out a true 1000w rms. I'm not talking about the percentage of time it does this, or any other off the wall variable you can come up with in your over-calculating little head.

Number one, a sub is much more prone to blowing in a ported box, no matter what wattage you're throwing at it. Number two, there's a reason why manufacturers put rated specs on their equipment. Overpowering a sub AND throwing it a big ported box is never a "safe" situation. Number three, I talk from experience, something that anyone who has been in car audio for more than several years will tell you is way more valuable than anything you learn in school, textbooks, theories, or calculations.
