Hey Pusta welcome to the Aperion family, I don't have answer to your question myself as I am also new to this. (it was so much easier years ago when all you did was plug in receiver, hook up speakers, add a cassette player, and if you were feeling fancy add a graphic equalizer.) But I have picked up a little in the forum. If I'm wrong someone will correct me but I would start with running towers at full, and satellites at around 80hz. You can go from there and play with settings til it sounds good to you. Try both at full, both at 80, move from 80 up to 100 or down to 60. Just keep playing in about 20hz increments until you get sound dialed in. If no one else chimes in I would say go to best source for Aperion speakers, the Gurus, they can be very helpful with all questions. Also check out Aperion University on the website and see if the answer is there. Happy listening.
