91sdime Posted December 21, 2010 Report Share Posted December 21, 2010 I am new to building subwoofer boxes so please bear with me. The sub my friend has is the Memphis Audio CM12D2 and requires a 2.44 internal airspace box, with a port of 12.5" X 2" X 25" I have tried using the box calculator but I can't get the tune at 36Hz, it says it will be tuned at 29Hz with their specs. But when I make the internal airspace of the box 1.7 with their port specs its 36Hz. I am really confusing the hell out of myself with all this stuff, shouldn't be attempting something like this lol.

91sdime Posted December 22, 2010 Author Report Share Posted December 22, 2010 Yes it would be greatly appreciated to help in figuring out a design, and kinda helping an idiot out where he shouldn't be sticking his nose lol. I just don't see in paying $150 for a box I can ask a couple questions and end making for $40 lol. Link to comment Share on other sites More sharing options...
