I just got a Marantz SR7001 receiver and some Revel Concerta F12 speakers. The F12's are 6 Ohm's each and the receiver says on the back panel where you hook up the speaker leads minimum 8 ohm for the Front A+B channels and 6 Ohm min for the surrounds. The manual doesn't say any more than read the back panel for what ohm loads you can run. It does give a rating for power at a 6 ohm load in the manual. Do you think I'm ok to run my 6 Ohm speakers with that receiver?
