Glad I do home auditions,found the MC-1's very enjoyable for surround work.
Even though they were X-over at 100hz,the right side seemed to have some mechanical noise as if the ribbon would
be vibrating on something.
Wendell suggested perhaps a 120hz X-over point.
As the room is only 12WX19D,volume wasn't thx levels(-19)on the dial.
Perhaps using another sub between the 4b-sst and surrounds or I'm thinking another home audition with the MG-12's next week to see if they give me more of the same.
I have not much room behind(3'-4')so maybe the 12's are to big,size doesn't matter,it's the sound quality
