Hello last week I upgraded my front tower speakers from energy connoisseur Cf-30 to the energy reference RC-70. My two rear channels were hand me down Kenwood bookshelf speakers do I gave them the heave-ho and am using the CF-30's as my to rear speakers. The current center is a hand me down Kenwood. I was wondering since I am unable to get the energy reference lcr to match the rc70' would the energy cc10 do alright? Also if it matters I have a pair of Polk psw111 subwolfers.
