Sub box porting is this too much?

Rave'n Silver Member Username: Goatin U.S.A Post Number: 698 Registered: Jan-06	Posted on Wednesday, April 05, 2006 - 02:30 GMT I want to build a new box for my R's so that I can port them. The plans I have drawn up now give it 31" of port space in a slot port with about 1.65 Cu Ft Gross airspace before displacement of the sub. Will this work? Or is it too much port for it?
