i need a centre speaker to go with my m73 fronts. i know that the m7c1 and m7c2 are the obvious choices but can`t get my hands on them at the moment. i can pick up a 77c1 straight away,as an option. i know it is from a different range, and have read all the arguments about the tonal balance etc. but will it really be that bad? the m7c1 and m7c2 will not be available until the new year and i don`t want to wait that long. will the 77c1 do?
