I know this is an easy one for some of you guys but I am a newbee so I need some expert advise to avoid wasting time and money.
I am building a dual 18" cabinet based on the SR7419x cabinet. I love the sound of this cabinet but I want to take it up a notch and put some 2242s inside of it and retune the ports. I will be building something from scratch so that I dont have to mess around with the origional cabinet.
I am also doing someting different though. I am using the shorter dimension of the cabinet as the baffle and the width of the SR as the depth of the cabinet. The box will have internal dimensions approx. (24"W x 48"H x 30"D). That's about 10ft^3 per woffer.
If I have a (6"x18") rectagular port (similar to the SR), what would be the ideal port length to provide a frequency responce down in the 30s?
Anyone have any experience building something like this or could point me in the right direction, I would appreciate it.
