[QUOTE="RAM_Designs, post: 7701784, member: 566575"] Because really, required port area has absolutely nothing to do with what size box the sub is in. Whether it's in 1ft^3 or 5ft^3, the air displaced by the sub is going to be the big determinant of what is the "safe zone" for avoiding port noise. It's just that people tend to use the same size box for 10's 12's etc, so the rule of thumb tends to be ok in most cases. I know Nick at Obsidian is a big supporter of NOT using large ports, but using smaller aeros to maintain extension below tuning and keep peakiness down. And with aeros, it's easy to use a smaller port and not have to worry about port noise. [/QUOTE]
