A foreground music sound system includes at least one complementary array of speakers (12) comprising a bass frequency speaker (20) and a plurality of microspeakers (14-18). The complementary speaker array may be designed to provide full frequency response with substantially uniform sound coverage for a wide variety of acoustic environments. A current amplifier (25) is responsive to a music signal input and a microphone signal input to directly drive the speakers. The amplifier (25) is a high current, low impedance amplifier so that it is capable of driving a large number of speakers, without the need for matching transformers at each speaker.
