Other than the papercone deteriorating over time (still in decent condition), what other maintenance is required for these units?
I love the horns, but just like ID's (Image Dynamics), they are a PITA to tune, especially w/10 - 33 band EQ's. Any secrets you guys would like to share regarding tuning, and optimal performance. Yes, I know sound fields influence the settings, and this is just a generalized question, since I have been out of home audio for many years now.
I haven't really noticed any degradation in sound quality yet!
Thanks
