CHAPTER 2 – THE PROJECT K2 S5800 LOUDSPEAKER: A TRIUMPH IN ACOUSTICS AND TECHNOLOGY stable pinpointed stereo image. All the sound seems to come from the combination horn in the center. Music imaging is more realistic since the sound appears to emanate from one point and not from multiple points at different times. Project K2 is a constant-angle sys- tem without regard to frequency. Careful horn design enables the loudspeaker to strictly adhere to a 60° horizontal/30° vertical coverage pattern.

CHAPTER 7 – PROJECT K2 S5800 SWITCH OPERATIONS The K2 S5800 has two switches mounted on the network panel on the rear of the enclosure. The switches are covered by an access plate which is easily removed by unscrewing the two mounting screws. See Figure 8. The Network Mode (Bi-Amp) Switch™ (center) should be left in the Normal position except when bi-amplification with an external electronic crossover is to be employed. The necessary cross- over slopes for the K2 S5800 are very specific and b
