Hello. Im soon buying this receiver and a pair of Monitor Audio Silver S1, which will later upgrade to 5.1 These bookshelfs can do 45Hz pretty well which means i can set crossover low like 50Hz. This tx-sr501 receiver is one of rare having option to change crossover frequency but 60Hz is the lowest. My question is will i want to set CO lower than 60Hz?Is there receiver in this price range that has better CO options? Although ill use 2.1 for quite some time ill use it for dvd, music, games, but most important are music and dvds.
