I'm building a large 4way tower simmilar to the NHT VT series. It will have 2 sepearate chambers with a side firing (closed)10" woofer on the bottom, and a 3way, vented chamber on the top (8", 6.5",1"). The mid will have its own enclosure in the upper chamber. The dimensions of the upper chamber are 22H x 9.5W x 25D, all in 3/4 MDF. My question is regarding the port. WinISD gives me options for various port diameters. Is it generally better to go with wider and shorter, or narrower and longer port, whats the difference? Space is not an issue beacause the cabinet is very deep. I'm planning to put the vent on the back, directly opposite to the 8" woofer. Also, the 6.5" (radioshack 40-1011) mid woofer will be my midrange driver (800hz-5000hz). WinISD recomeds a ported enclosure but I'm not worried about its base capabilities so I'm putting it in a small 3.3l closed chamber. Is this okay? Sorry for the long post.
