so your trying to tell me that 4 4" aeros would be great for a 5.5 cube box....well i have alot of people here who will disagree....but to each his/her own.
Yeah, actually....for anything other then pure SPL it IS enough port. 2 6" aeros is PERFECT for 6cu.ft and 4 is PERFECT for 12.
Honeslty OP, I'd say use aeros. It's pretty much proven they aren't too good to be true. They work wonders //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
