I own the Athena AS-C1 and a pair of AS-B1s, as well as the remaining sub and rear surrounds from an old Sony HTiB. The problem I have is I am constantly turning the volume up to hear normal voices and then have to quicly lower the volume when the music or effects start. I have set the speakers to the same levels in the audio tests on my HE setup disk. Is this a normal problem? I am currently running a Yamaha AVR.
