It was a nice review. I watched for it and was happy to see them post as they did. I bet they had v3 tweeters...I found my v3 tweeters didn't like -7.5 either. At -10 everythings great. Good thing -7.5 isn't normal listening for me. And...v4 tweeters got installed tonight. Too bad I won't hear them until Monday night. Port plugs...might have been the next best thing for the review. All in all great honest comments.
I downloaded HTS's pic & zoomed in on the M100 tweeters. Although the pic is quite dark, they look like V4s to me.
I find that with my M22s + 2 X Velo Subs when playing music in my HT system, anything over -15 Db gets too loud for me - unless I'm into the sauce, ha! I recently watched Eric Clapton with Steve Winwood DVD 'Live at Carnegie Hall' in surround & found that -20 Db was most comfortable but still dynamic & enjoyable...
