I just got last week into a new Elite 49TXi and I love the sound. Seting it up and using the MCACC was really helpfull and easy . My concern now is about my speakers which are a 4 Ohm M&K 150 THX series and the AVR manual look for 6-8 Ohm speakers. Will I get into any trouble running my 49TXi with this low Ohm speakers? My room is a 18'x18'x9'
