[QUOTE="THATpurpleKUSH, post: 7519191, member: 615398"] Shoot for 14sq in of port for every cubic ft of box volume for that woofer. Ex- 2 cu/ft box = 28sq in of port. Round ports are more efficient so they don't require as large of an opening as slot ports. With a 12in woofer, you should never go smaller than a 4in diameter if using a round port or you will have terrible port noise. [/QUOTE]
