Hi. I have read countless articles on home theatre setup on the audioholics website. A year ago I bought a rxv667 Yamaha receiver along with Monitor Audio M Series speakers. I have the M 4s M1s, M centre and the MW10. I use the auto setup with the receiver. I always get the fronts set to large as well as the surrounds but the center channel gets set to small with a crossover of 160Hz. It sounds good to me. Now I have also changed everything to small and the sub crossover to 80. What would people recommend? According to most articles, everything should be set to small and a crossover set to 80. Any opinions?
