Generally, threads get locked when nothing new is being said, when efforts to keep things moderated seem to be failing, or when things seem to be getting out of hand in terms of attitude and personal comments. Tough call to make sometimes, and even tougher to make sure everyone feels like they got their licks in first. Just so folks know, debating moderating decisions in threads - rather than by PM's to the moderators or admins - is not viewed kindly here. It is nice to see Klipsch folks hang out here, and I hope it doesn't call for much attention from the mods.
