Came home from work and checked the numbers. At 250 Liters given manufacturers specs and 2 Acoustic elegance PRs 18" at 3117.5 grams each
OOPs 3,000 watts gives 109.6 db at 10hz. Imagine with room gain !!

Chris, I do value your subjective opinions regardless of how bias they may be.
Since you haven't listened to a PR system as of late, give one a try. AE has the 15" PRs at 1050 grams Fs 4.63hz xmax 2" p to p on sale for $50.00. Two of these would work nicely with a SDX15 if you've got one layin around. I'm gonna model em now with one of those TC sounds closeout twelves from PE. Will post in a different thread. My opinion will be as subjective as possible of course ! LOL.
Do you mean you modeled the JL13W7 at 3000 watts? If this is the case, I don't think that is at all an accurate representation of what to expect. I recommend using the driver's rated RMS 1000 watts, and then de-rate the results by another 2 or 3 dB, in order to get something closer to real-world probable performance estimates.
