With crystal clear sound penetration, K-series two way full range loudspeakers can be used for indoor sound reinforcement of KTVs, conference rooms or other venues of similar size. The 50 -100°×55° constant directional unsymmetric rotary compression horn enables both vertical and horizontal installations of the speaker boxes. Flat frequency response together with accurate crossover guarantees excellent sound effect. Blended with 15" active or 18" passive subwoofers, the two way full range loudspeakers are able to produce different styles of music perfectly.
