I've done some rather lengthy hunting on line and yes there are some very impressive room correcting devices out there than can do most if not all of what I was looking for but they are very expensive. The least expensive is in the $2,500 range. Unfortunatley I don't have $2,500 to burn. There are some less expensive paramaetric equalizers that perform some of these functions, such as the Behrningers. But none totally fit the bill without spending a whole lot. I'm wondering how much difference the SMS-1 itself would make? It really does everything I'm looking for but it's just limited to the sub-woofer freq's. I know proper managment at those levels can make a significant difference, and it's pratically a steal right now at $399.
