The freqencies as stated above are related to an eq on the Sony.I just read the manual and you can run the reciever with the eq off.That should give you a flat responce,you should just leave the eq off and and you will be fine.

Also in the manual it suggest to start with 0db on the LFE and adjust it as needed.
