The way he has it designed now is good but I just wanted the port in the middle to make it have a balanced look. I know he is really busy designing boxes so I was wondering if someone could help me. "What I came up with is a 3.75ft^3 box tuned to 32hz. This will give you the exact same response, but give you a 3db boost and extend the playable bass range another 4hz. The port is quite large which will yield a bigger SPL boost and no chance of a problem with port velocity (port noise). This design will have a very smooth response with very high SPL gains, as well as a very safe design. it is tuned low enough that you will not really have to worry about harming the woofer itself." The box dimensions would be: 4.58ft^3 tuning freq. 32hz port dim. 3" x 14.5" port length 23.5" W 32" x D 19.75" x H 16" Port: H 14.5" x W 3" x L 23.5" (2) front/back: 32" x 16" (2) top/bottom: 32" x 18.25" (2) sides: 18.25" x 14.5" (1) port #1: 14.5" x 15.25" (1) port #2: 14.5" x 3.75" Box Diagram: http://www.geocities.com/boxbuilder777/jlw6v2-2.jpg |
