(Although I don't think Steve has Series II speakers in his Imperial SO's). Dan

merry Ex Member	Re: Driver for SO imperial Reply #4 - 07/11/08 at 18:25:53 Ok, but the Vas on the Dayton is : 9.64 cu Ft and Steve was recomending that it would work well in a 4 cubic foot sealed enclosure. Ain't that a to much of a difference in number's (rememder i'm a newbie so my questions maybe dumb) Thanks for the help. Merry from Sweden

Merry,

Welcome to the forum!

VAS is the a specific volume of air which has the same compliance as the driver, it does not mean that the driver needs that much air space. With that said, the Dayton driver, which I have put into 4 different IMP SO's does sound great. In a sealed box, not horn loaded it would need a 2.17 CU FT box for the flattest response.
