Hey folks, New to the forum, picked up a pair RP160-M's yesterday on a good deal, got them from a good speaker store in my city. I trust the guy that sold em to me, but still want to confirm if the receiver he sold them with provides the appropriate amount of power. He sold me the Onkyo TX-NR575. It's currently setup in a 2.0 mode, but going to pick up a sub today. From what I have researched, with the speakers being set in 6ohm via the receiver, there should be more than enough power for these bad boys. But don't want to damage them in anyway, not a super loud listener, just looking for crisp and clean. Any help would be appreciated. Cheers! Also, apologies if this is a repeat question. I can't get through to klipsch support, and can't really find straight forward answers online, or any forums with someone that has the same setup. Thanks in advance.
