[QUOTE="squeak9798, post: 768818, member: 555320"] Simply a box with a side missing would not work since the front wave and rear wave would not be isolated from each other. However, your idea of having a box with an opening filled with a semi permiable substance would work wonderfully......and it actually has a name [IMG]//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif[/IMG] It's called an aperiodic enclosure; The box only has to be large enough to house the subs themselves, and no larger.
