All Ohm Home Theater systems are mix and match. You can start with a 2-channel, audiophile music system and later expand it to a full-blown 7.2 system with nine matched speakers. When there are receivers on the market that can do it, you can even go all the way to a Dolby Atmos system with twenty-four distinct main and surround channels, one subwoofer and ten ceiling speakers. Other brands of sub-woofer and rear/ambiance speakers can be mixed with the Ohms. As long as the three front mains are matched Ohm speakers, you will enjoy the unique benefits of Ohm Walsh speakers: natural voice reproduction so dialog is clear at all listening positions and accurate, stable imaging on well recorded music.
