hello all, Im running a Onkyo Tx-sr805 and I have th epleasure of owning rf-83's, my question is what should i set them at...full range? to a certain HZ like 80hz, i used the calibration mic but i feel as if my rf-83's arent putting out the sound that they can, i am a bass loving kinda of guy and like to feel it if you know what i mean....any help would be a GREAT help, also if anyone is a Receiver expert, should i keep the onlyo tx-sr805 or get the tx-sr636?
