I must have v3 since the tubes are 2.5 inches long. I'll have to research this some more to figure out what would need to be done to the xo's. Thanks for the help.
Would a longer port tube from parts express that is 4.375" in length compared to the 2.5" original tube make any difference in sound on a CF3?

Cornwall's available for the same price $1100 and the same market place.

Doesn't sell raise the price. Inflate demand?
