Hi, I have an Audigy 2 ZS with a Z 5300 Speaker. I would like to know what are the settings that everyone use with this speaker and KX drivers. Personnaly, I only use a Timbre and EQ-10 with each connections ( one for the front speaker, one for the rear speakers and one with the center speaker ). For the EQ I decrease the low frequency ( the first 3 frequency )and increase the high frequency. I use the timbre to increase the treble ( +5.1 db ) and decrease the bass ( -3.0 ). For the Subwoofer I use only a volume dsp ( for reducing the bass because the bass are too present on the Z-5300 ). Finally I've decreased the bass level on the remote control ( level 2 ). Anyway the sound is definitly better with the KX project ( specialy the quality and the expansion ( 2.0->5.1 ) has nothing to do with the CMSS thing... ). I use my PC for playing, watching DVD and for listening music ( every type of music, but specialy alternative, rock, classical, soundtrack ). Btw, I don't know if there are other that can be used to improve the sound quality... but I've got some trouble using them because they are not documented. Cheers !
