Product Details

The R6-51 three-way full-range loudspeaker system is engineered to provide quality full-range long throw sound

projection in a variety of outdoor and indoor applications. Its very high output, wide range, smooth frequency response, and high efficiency ensures both high fidelity music reproduction and superb projection of clear intelligible speech with very low distortion. The system is configured for bi-amplification for an active crossover for the LF to MF/HF sections and has a passive crossover for the MF to HF sections. The R6-51 is an extremely capable system using an innovative all horn loaded design of multiple driver vertical line arrays. The resulting output and coverage pattern is ideal for applications requiring high impact, long throw full-range performance.
