[QUOTE="Farside, post: 443558, member: 554476"] I'm building a box for my 12" Type R using a 4" port. I believe [B]Jmac [/B] helped me with this earlier, but I'm trying to fit a 22" port into a box with a gross volume of 2.15 ft^3. right now outside dimensions = 14" x 16" x 22" I was told to keep the port a minimum of 3/4 Dia (or 3" in my case) away fromthe walls of the enclosure and i'm using a 90 Deg elbow to do it. My trouble is that the port runs under(or behind) the sub, but comes close to to bottom (magnet) of the sub - 1" to be exact. Is this way too close? Do the same distance rules apply for the walls and the sub? I could move the port farther from the sub, but this would require that I make the box slightly bigger than originally calculated ( WinISO shortens the port length to compensate for this) Thanks, [/QUOTE]
