Ed, If I add the extension, indicated with
cardboard w/lines, I have the original 22 1/4 sq. in's. If I block off the
cowl openings to match the diffuser, I will have 18 7/8 sq. inches. The
neck at the smallest point is approximately 15 sq. inches as close as I can
determine by my barn door math. Which is the better way to go, opening
wise, the larger or the smaller opening. If these numbers are in the ball
park, I'll lay up the glass. Thankyou
