Simple consideration for size; do NOT buy a speaker that is bigger for the room than what is needed. A person may be drawn to the general bigger is better trap, but when it comes to sound, you will find it VERY hard to place a large speaker in a small or not adequate space. Our HT room is a very near example of this. I cannot quite get as broad a sweet spot as i would like with the M60s because we sit 11 feet from them. I need about another 2 feet to get that broader sweet spot.
Chess, how big is your room volume? Dimensions?.....that your m60s are in now?
As posted 13.5 w x 16 L x 7 H in feet so the volume works out to about 1500 cubic feet. I have had them up in our main floor living room though off the side of our open floor plan kitchen. That room is about 18x 15 x 10 so 2700 cubic feet not including into the dining and kitchen areas or it would be well over 5000 cubic feet.
It has been awhile since i had the M60s on the main floor for a listen, but i do recall that they were bright (the room has a lot of hard surfaces though) but the stereo imaging was much better. We sit about 13 feet from the system again on the short axis of the rectangular room.
I may for kicks bring them back upstairs to test them out for sound as a refresher.
