I've spent countless hours designing this box for a 15" K that will fit my application the way I need it to.It has about 3.7^ft of airspace after driver and port displacement.My problem is the port.I was going to use an Aero-Port but I dont have the room to do it on the box,so my next idea was the slot port which is what you see here(the red line).My question is will this be alright?I know the port is suppose to be on the same panel as the sub,but that is not an option here.Any ideas/advice will be greatly appreciated......thanks
