The HR-28 enclosure is a high-performance passive full range, with an excellent power-size ratio. It consists of two 8” hexacone transducers and a 1” high frequency compression driver. It offers a wide dispersion of 90º x 60º and 126 dB SPL (1000W program).

This enclosure offers a selectable operation between bi-amp or passive mode and is ideal for a wide variety of applications. Although this cabinet can be used without a processor, we strongly recommend that the cabinet presets are applied for maximum optimization and performance.
