The R800 is a combination FM receiver/amplifier/speaker. The SPK 800 is driven by the
amplifier within the R800. Both are compact, self-contained, and portable. Most rooms will
require just the two speakers, placed in either front corner of the room. For larger rooms,
additional speakers may be added to the rear corners.
