Thank you John for the detailed reply. I see that you actually looked at REL settings. I appreciate it. I will take your advice. In addition, I will add the high-pass connection, since I can still do it with "full band" settings for M60s. It is probably a good solution especially for a two channel stereo. I will simply have to find the time to do it this weekend.
