[QUOTE="xluben, post: 2442775, member: 568852"] well, he gave me some measurements and this is what i came up with: (side view): [URL="http://img224.imageshack.us/my.php?image=dansboxsidelb4.jpg"][IMG]http://img224.imageshack.us/img224/1593/dansboxsidelb4.th.jpg[/IMG][/URL] and 48" wide. that shows the passenger side of the box with the 3" x 7" port opening, which will be 18" long. that comes out to about 1.85ft^3 @ 35Hz w/21in^2 of port area. not ideal, but the best i could come up with for the measurements he gave me. here's the winisd plot of the transfer function vs. a 1ft^3 sealed box: [URL="http://img224.imageshack.us/my.php?image=danstranferfunctionaf9.jpg"][IMG]http://img224.imageshack.us/img224/2705/danstranferfunctionaf9.th.jpg[/IMG][/URL] as you can see, a pretty good gain in max amplitude and a considerably (>10dB) lower peak and f3. i was a little worried about the small(ish) port, but winisd only shows it being a possible issue with a full 400W between the frequencies of 23 - 36Hz. on music i don't think that should be too much of a problem.
