[QUOTE="SPLEclipse, post: 5256049, member: 602411"] at 1.85 ft^3 gross (after all driver/bracing displacement but before port displacement), you will need 6.274" of length with a 3" round port. your net volume will be 1.824 ft^3. the tuning is at 35hz. also (something i forgot to mention earlier), [URL="http://www.psp-inc.com"]http://www.psp-inc.com[/URL] always adds and inch to port length measurments for flared designs. im not sure why but you should check out that site for sure. thier port lengths for non-flared designs are off a little though.
