I am looking at purchasing either the 60's or 80's. Either will be run bi-amped from a Carver AV-705X. My listening room is 15x14x8. I use it for about 50/50 HT/Music. I am worried that the M80's will be to large for my room. Which would you recomend. I am leaning towards the M60s if I dont sacrifice any sound quality, imaging, or anything like that.
