I often play small dinner parties, providing easy-listening background music. I use the onboard speakers of the S970, but augment the sound with a pair of small, bi-amped 4-inch monitor speakers----about 40 watt powered speakers. There is plenty of sound to fill a room easily. I have two other larger systems. But, in many instances, that’s simply overkill for what the client wants, or what the occasion may call for. The money’s the same irrespective of the PA system.
