I've got the Newform Research Monitor 30's and the soundstage and imaging are great. The sweet spot, about maybe 2 people wide, but it is listeable in much wider area. They have that great airiness of electrostatics. These are made to mated to subwoofers so not directly comparable to the 645 series. With only a 30 inch ribbon, you can definitely tell the difference when you stand up. These speakers definitely need a quality subwoofer. I need to upgrade to a faster one. I have some of the rare full length grilles, which help their odd apprearance, but they sound better with them off
Thanks, just my two cents worth.
