After a lot of reading here and looking at my manual I decided to check the test tone on my system. I have a Sony DE545. I have the fronts and rear set to small. I have a sony sub set at about 80hz and 3/4 power. When I hit the test tone button on my remote they all sound about the same until it gets to the sub. It is very low. Is this right? I have the volume control at about 13.
