Hey everybody a real newbie hear but here it goes. I have some Cornwall cabs ( no drivers,I was going to put 511b's on top, but thought I'd try this first) that measure 25.5 W x 36 H x 15.5 deep. The 620 measures 26W x 40 H x 18 D Can I add about 4.75 inches to the front and get about the same volume as a 620. If I did my math right it seems like it may work. What are the downsides to doing something like this? Would that make it too square? Does that matter? What port size sHould I use. The same as a 620 right? Any reason to leave the port shelf and vent like the cornwall? I'll be using 604-8h and maybe talk to GPA about some crossovers. Any thoughts would be great.
Thanks in advance
