[QUOTE="trumpet, post: 8549336, member: 628688"] I don't know, I don't deal in applications that would require 80+ sq. inches of port. I was looking at this in WinISD Pro with a different 750W RMS subwoofer I have in my database and I entered a port that is 1.25" W x 11" H x 22.4" L. That is a normal sized port for a single 12" on 400W, and it comes out to a tuning frequency of 30.66 Hz. Are you totally sure the port is 4.5" x 18.5" at the outside of the box? That's wide enough to put your fist into it plus it's half the height of a yard stick. [/QUOTE]
