I'm getting the b&w 603s3 will be using the rotel to power.My question is what would be the proper speaker settings for this setup.My receiver allows for individual crossover settings.Should i set to small /large/sub yes/no etc.Would like to also know what crossover should i use for all the speakers.Use will be 75-80 % ht/tv,rest music.Right now i will be using unmatched center unfortunatly until i can afford the correct one.would appreciate the help.
