unfortunately, my first impression is that i do not like the way this speaker looks. it looks kind of like a box, but it's not a box... Ian, maybe if you could re-arrange the drivers to make it more symmetrical some how? My initial though was to add a second 5.25" and put the tweeter in the middle... But then it wouldn't have the exact same drivers as the m60..

Sorry to be the negative Nancy in the group, but you deserve honest feedback, so that is what i am giving you.
