When you use a dual port design in winisd, do you divide the port length in half, or each port has to be that length they give you??

Thanks Jmac. One more question if u dont mind. Ive herd many times that you should keep the port velocity under 40m/s, however when i try out many of the manufactures suggested box reccomendations, the port velocity between 30 and 40 hertz is up near 75 m/s. Am i doing something wrong??

so then ur advice would be to forget their design and make my own. Problem is that when i try to keep the port veocity down around 40, my port length become very, very long. Is there someway to avoid this or u just have to have real long ports.

wait, my bad Jmac, in winisd my graph was on ft/sec not m/s. Thats why my ports were so long lol
