[QUOTE="Jeffdachef, post: 8363051, member: 650438"] do you know what tuning you want for the subs? because ports have to be tuned properly. what music do you normally play? also for the port design, lets say for example that big port in the middle is 7 inches wide, and when it starts to bend, since it splits up, each side will be 3.5 inches wide afterwards. For the software, you'll want at least 1 cubic feet for each sub with 12 to 16 port area per cubic feet. Be sure to include common port walls and displacement of the subs which is .1 cubic feet per subwoofer. The tutorial for torres is on the download page which will show you what common port walls are. Port length is not how long the wall needs to be, its a measurment straight down the middle of the port. for example its the red lines in the box designs on this page [URL="http://www.srtforums.com/forums/f40/official-free-ported-box-plans-56k-no-435910/"]http://www.srtforums.com/forums/f40/official-free-ported-box-plans-56k-no-435910/[/URL] Use that to figure out how to do a proper port length. Example of a design after I take away 15 inches for both side 6.5 speakers. [IMG]http://snag.gy/VrRKr.jpg[/IMG] [/QUOTE]
