I had 645's. They image and soundstage incredibly well.Bass is tight and fast but not tons of it.They are a bit lean sounding,very fast and clear.They look weird,need to be pulled out a bit into the room and can handle dynamics and power.Good value,but check if they are right for your room.Although in some ways I miss them,I needed more bass,and more conventional looks. They sure do float a piano into the room. They can be trialed,but do your homework first. The owner of the company is a real nice guy to work with. Take care--
