[QUOTE="beerman, post: 1111108, member: 561845"] I thought about adding a "port position" selector box. Options would be "side", "bottom" and "CRX". Side is "standard" while "bottom" and "CRX" would have to work around the woofer basket. Difficult since the ports are enormous with those designs. 9:1 ratio with a 40" wide box would yield a 38.5x4.25" port, or nearly 164 square inches. Not really a problem with high-excursion woofers, since the port is going to be that big anyways, but many people wouldn't want that for two or three "entry level" woofers. [/QUOTE]
