I have a Boston System in my sun room and I want to upgrade the surrounds. This is the system: CR85 Fronts VRC Center Yamaha RX-V630 onkyo Surrounds from HTS650 system The room is about 12 x 22. The surrounds have to be mounted at about 10'. I was looking for CR65s or CR75s. My question, would any of the following work well? CR55, too small?? CR6, CR7, or CR8. I don't know much about these. Energy c1. I'm curious about these. When I listed to them they seemed to be a good match to the Bostons Any thoughts?
