OK, I hope I am not being a pest here, but if I go with the 4" tube that flares at both ends to meet the 7.25" flange, what length should I cut the tube to (and does that include the short flared section or only the part of the tube that is a straight 4" in diameter)?Thanks in advance for any help... first project other than single driver / open baffle... and I am math challenged.
Regards,
Greg Jensen
