I am running a yamaha rxv671 10 inch svs Yamaha f&r presence for my 7.1 Yamaha center Dayton audio front l&r Rear l&r bose 301 series Id like to replace my two fronts i have 2 6.5s in a tower at 29 hz. They give great mids but i need a little more. Id like to put in a couple higher quality 6.5s with a external amp and some tweets. Ill need new crossovers the two speakers and a nice amp. Id like something that can run solo on 2.1 with my svs. Thanks guys
