Large ports are peakier around your tuning whereas smaller ports have flatter responses

Those type r's will handle 1500w no problem. And I hope that when you say 10 cubes that is a typo. Do you mean 1 cube?

sorry 10 inch of port per cube

Ah alright. 10 per cube is pretty small, usually I try to do at least 12. And those subs are rated at 600rms but can take more as long as the power is clean and you aren't stupid about it. I would bump your port area up to 13-14 that should give you a good amount of extra output. What space and tuning do they have?

his current box is 1.5 per sub net I believe......we were discussing an enclosure closer to 2 cubes per sub......with roughly 14-15 inches of port per cube

If you are capable of building your own boxes, I would do something like 4 - 4.5 cubes @ 34-35 with 13-14 in^2 of port per cube. If you don't listen to many lows, raising up your tuning a bit will give you a lot more output.

EDIT: sounds like you are already taken care of, good luck!

33"w x 24"d x 16"h........with a port that is 14.5"h x 4.5"w x 32"d.........It will net you a little less than 2 cubes per sub with a 33hz tune and 15 inches of port per cube thats the box i lookin at

Not a horrible enclosure idea. If you can go larger I would though.

Also make sure you round over the port edges and put at least a 45 in the L of the port and try and make that 45 large enough to keep the width of the port correct through the bend.
