I am building a 8.5 cf ported box to house altec 416's. its supposed to have a 6" x 10" by 14" long rectangular port. How in the world to you build this? can you buy such big ports pre-fab? I notice partsexpress only has small circular ones.second question. is there anything wrong with cutting out the driver opening using a jigsaw? I know people use routers with circle cutting jigs, but if I'm flush mounting the drivers, wouldn't free hand jigsawing work ok?
thanks in advance for any advice or suggestions, Kevin Grier
