Due to a large amount of requests I have spent some time designing a simple version of my Infinity Kappa VQ Build. These plans would likely be easily completed by someone with wood working experience in less than one day. A novice would probably want to take more time, but shouldn't have much trouble with this design.\r\n\r\nThe graphs:\r\n\r\nTransfer function:\r\n\r\n\r\nSPL versus frequency at 400 watts:\r\n\r\n\r\nCone excursion at 400 watts:\r\n\r\n\r\nPort air speed at 400 watts:\r\n\r\n\r\nThe CAD design:\r\n\r\n\r\nThe cabinet is 22.5" wide x 22.5" deep x 25" tall with a port that measures 12.5" wide x 55" long x 3" tall.\r\n\r\nWith the top taken off:\r\n\r\n\r\nFront baffle and top taken off:\r\n\r\n\r\nSide taken off as well:\r\n\r\n\r\nOne cross brace removed as well:\r\n\r\n\r\nCut list (Use 3\/4" cabinet grade plywood):\r\n\r\nFront baffle: 21" x 24"\r\nRear baffle: 22.5" x 24"\r\nSides: 21.75" x 24"\r\nTop\/Bottom: 22.5" x 22.5"\r\nCross brace (large): 16.5" x 21"\r\nCross brace (small): 6.25" x 21"\r\nPort bottom: \r\n2x 18" x 3"\r\n17.25" x 14"\r\nPort back:\r\n2x 24" x 3"\r\n18" x 14"\r\nPort top:\r\n2x 13.75" x 3"\r\n13" x 14"\r\n\r\nYou will want to get some OC705 or 8lb Rock wool to place inside the cabinet. Use a 4" piece wrapped in cloth (to eliminate chances of pieces being blown out the port) and glue it (using 3m Spray 77) to the large brace.\r\n\r\nRecommended amplifier EP2500.\r\n\r\nThats everything. Optional things you can do to increase sound quality:\r\n\r\n1) Round over\/cove the port corners with a router. This will decrease air turbulence and minimize chances of port noise\/compression at high SPL.\r\n\r\n2) Integrate the unit with a DCX2496. This will also allow for equalization of your subwoofer for maximum perceived sound quality.\r\n\r\n3) Build 2 and integrate as a stereo pair with the DCX.\r\n\r\n\r\n**Please note I make no guarantees about actual performance as there are a variety of factors that effect such a unit.***\r\n\r\nFeel free to ask any questions either here or via PM.
