And I am looking to bi amp these 6300's too since I want to tone down the bass as well. Never would I have ever guessed that I would be saying that about a tower speaker. How the heck did RBH Sound get so much bass in this tower. This is a positive, not a negative.\n\nI guess the six of the 6" woofers per pair of towers equal to about one of the SX-1010 subwoofer. I tested one SX-1010 sub in my 18' x 20' x 12' family room, and it was shaking the walls like a rag doll. :eek: So I can see why you are getting a lot of bass in your room. \n\nWhat are you thinking of using to bi-amp the SX-6300\/R towers?
