Your room will affect the PR enclosure and sealed enclosure the same way. If you room has 12db of boost at 20 hz, both alignments will be affected by it.

Are you modeling both drivers off of the 3600w? I'm showing that one driver would be over 45mm excursion at 10hz in a 3ft box with that much power. The drivers are 4ohm so the CE4000 will be giving about 1200w to each if you run both off of one amp. Use a 3rd order Butterworth HPF at 8hz in your modeling. That's what's in the CE4000. If you reduce the box volume to 2.4ft per driver you should be ok throwing 3600w to each driver with no filter.

All that I'm saying is that the LMS drivers will bottom out hard and damage themselves if driven too hard. He will have enough power on hand to do it in the 3 foot box. It might take a very rare event to do it, but I'd rather not take the chance that it ever does. The further you get out there into high excursion, high power combos, the less room for error that you have. The LMS drivers hard bottom at 44mm xmech and they sound clean all the way up until "whack!".

Noooice...:T

How is the damaged CE4000 issue going?
