Yesss!!! Welcome to the 24 club sir!

I would go bigger if you can. Testing has shown 15 cubes sealed to be about the otimal size....bigger is better, but only incrimentally from there really, withing reason. 10 will work great if you can't go bigger, just some food for thought. I'd go d2 because you can wire coils in series for 4ohm stereo...nice easy load on the amp..crest amp with 2kw a piece....or if you wanna get a bit crazy go d1 and 2 ohm stereo for almost 4kw a piece biggrin.gif

Honestly that's what I would do with these if I were intending on using them in "small" sealed enclosures. The specs released are based on the d2 version. Now this is an assumption but if there were no other changes other than the coil being wound for the d1's then there is a strong likelihood that the BL has increased and that the Qes/Qts has dropped. This would end with a lower Qtc in 10-15cuft compared to the d2's.

Plus in the smaller cabs you'll need that extra power to use up all that throw. smile.gif

Yes sir I was looking at pro-lite 7.5 it looked like a good match whether it be 2 it 4 ohm load. Maybe I can get the 1 ohm version and get to more latter and run 2 per channel at 4 ohm load smile.gif . Just food for thought

Isn't Ricci supposed to get one of these 24's to test?
I read that somewhere...I forget where...
anyways. when is he supposed to get his to test?

Sorry for the minor derail...

Rhino11...congrats on a great purchase

No offense taken at all. That's just another way I'd go about using these monsters. In your case, probably not even an issue and really in the grand scheme of things...going with either one will present similar end results of performance and satisfaction. smile.gif

Can't wait all these projects with 24's. smile.gif

it depends on which amp you intend to run.

the inuke 6000 or 3000 (bridged) work with 4 ohms net well.

the prolite on the other hand can run 2ohm loads per channel. well, at least the manual says it can. :-) not sure if it is designed to run at those loads for short time frames or hours on end.

the cv5000 can run 2 ohm loads per channel as well. surprisingly, I've never seen it bench tested, but the amp that it is modeled on (crest ca18) has a pretty solid reputation.

all that said, the driver is only spec'd for 1500 watts. 1500 watts in a 15 cubic foot enclosure only gets the driver to about 25mm excursion. in order to take advantage of the massive excursion, either a really large box / infinite baffle is required or running the driver at more than rated power is required.

Listen. It's All Good.

also, it looks like on the website that today is the last day before the price on them goes up...if that is relevant in your case.

Yep, huge sealed/IB with rated power or much more in a 15 cube or less box. I can tell you this, you'll all know more for sure after this weekend biggrin.gif

The rated power really is comical...it's capabilities have been proven privately to be much, much more..more than double and serious abuse.

I swear I had seen a CV bench before I bought them, but can't find it for my life right now. Really solid amps and handle the load no problem at all.

You should be fine. You can always hook them up together for a 4ohm load at the very worst.

You don't have to buy two more to get a 4ohm load.

D1's are 2ohm with the coils in series. Two 24d1's (like you just ordered) in series would be 4ohm.

roger chop. if you happen to remember where the cv test was, please let me know.

without knowing the testing conditions, the "1500 watts" rating could pretty much mean anything. what bandwith, what signal, what crest factor, how long, etc.? maybe it is conservatively rated suggested amp power for folks who might get the urge to send sustained sine waves/bass drops through their gear. who knows...

sounds like the cv5000 would be a good match for the op's new acquisitions!

Listen. It's All Good.

I think it will be a great match. With regard to testing...A sine wave, long term at double rated power didn't bust it

Thanks guys I am looking to go sealed will see if I can pull off going with 15cf but you can check out my theater build when it goes up. I need to get on that soon. I have a dedicated space of 27x14x9 foe the theater all the walls have insulation and drywall. So I need to make decsion on the sound proofing. I want to build a room within a room, but I can do hat channel and iso clips if need be. Stage and screen wall. There will be about 3 feet or so Behind screen for room for the speakers.
