Bi-amp/tri-amp mid-high loudspeaker is consists of 1-inch high frequency compression driver on Dendritic horn, 6.5-inch high-mid frequency driver on patented Polyhorn device and two Turbo-loaded 10-inch low-mid frequency drivers. It combines Dendritic HF device and midrange Polyhorn in physically aligned, equal path length waveguide with 100° of horizontal dispersion, ensuring phase-coherent wavefront at horn mouth. The compact trapezoidal enclosure contains 1-inch high frequency compression driver on Dendritic horn, 6.5-inch high-mid frequency driver on patented Polyhorn device and two turbo-loaded 10-inch low-mid frequency drivers. The TCS-1061/100 is switchable tri-amp/bi-amp enclosure and includes passive crossover network between MF and HF drive units which can be bypassed via an internal jumper located inside the low/mid driver access door. Neodymium drive units are used throughout in order to achieve cabinet’s low net weight. Recessed panel at the rear of cabinet carries two parallel-linked Speakon NL8 connectors for input and loop-through connections. An external flying system allows the assembly of unobtrusive loudspeaker arrays in fixed installations with wide range of coverage possibilities. Front and rear flying strips are supplied with each loudspeaker.
