[QUOTE="Immacomputer, post: 5583429, member: 570419"] Hit the Print Screen button (next to F12) and then open MSpaint. Go to edit --> Paste and then save as a .jpg file. Then upload to a place like [URL="http://www.tinypic.com"]http://www.tinypic.com[/URL] and then post it here. The distance should be based around the total surface area of the air between the loading panel and the enclosure. This should be more than the Sd of the driver. For instance, lets take a 15" by 15" loading panel over a 12" sub with an Sd of 75in^2. The total surface area of the air mass would be 4*15"*h where h is the height off of enclosure. 4*15 = 45in. Now if we put the loading panel 3" off of the enclosure, the total surface area will be 3"*45" = 135in^2 which is more than the surface area of the driver so you should be safe. I would shoot between 1.25-2x the surface area of the drivers' Sd. [/QUOTE]
