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...
