OK I've narrowed my sub choice down to Kevins new tempest. Its modeling up real good in winisd and everything posted looks great. I keep seeing around 120db in room on these plans. The tempest is also a perfect match for my dayton 1000watt stand alone amp I already have. I want to modify the slot port design for my home and have a few questions. I've bumped my dimensions up some from my original plans. I'm wanting to go 20" wide by 20" deep by 38" tall. Slot port and sub both down firing. Will be a tight fit on the bottom but should work. The port will be 18.5" wide by probably 2" or 1.75" depending on room. Around 32" long I'm going for around a 20hz tune. I've looked at lowes and I can get oak in the sizes I want for legs and table top. 1x4 legs v on each corner and a 1" think table top. I'll go with a cherry stain on the oak and poly and paint the mdf black. The oak will hide all my screws so I don't have to worry about a million clamps. My plan for now is for 4" legs. I will probably double the mounting and counter sink the sub 3/4". Is 4" enough clearance for the port off the floor? Figure it's plenty for the sub. Winisd show around 20 to 25m/s on the port air speed. That box is 7.23 cubic feet and after sub and port/bracing should still be a little over 6cf. Is there anything else I'm missing? I should be ordering my sub/Christmas present soon. I haven't mastered google sketchup yet so here's my sloppy paint version so you see what I'm thinking.
