It uses Dolby's proprietary dual-entrant asymmetrical horn and custom compression-driver technology for consistent coverage and uniform volume shading. The system covers 31 Hz to 20 kHz with 28 Hz usable response and 136 dB maximum summed continuous SPL.\u003c\/p\u003e\n\n\u003ch2\u003eHow does the Dolby System 133 work?\u003c\/h2\u003e\n\u003cp\u003eThe CS136MH horn pairs a custom ring radiator mid-frequency compression driver, which covers the primary vocal range of 400 Hz to 4 kHz, with a titanium-diaphragm high-frequency compression driver. The ring radiator allows a lower crossover frequency, improving intelligibility and power handling. The dual-entrant horn keeps the drivers close together for pattern control, spanning 55° at the top and 100° at the bottom horizontally with 50° vertical.\u003c\/p\u003e\n\u003cp\u003eBelow the horn, the CS136LF carries two 15-inch woofers rated at 1400 W @ 74.8 Vrms in a braced wood enclosure. The advanced input plate's flip-card PCB selects tri-amp or bi-amp system configurations, and the spring-loaded terminal blocks allow tool-free connection. Laser aiming sights in the horn work with a common laser pointer and the tilt and pan mechanisms for fast, accurate aiming.\u003c\/p\u003e\n\u003cp\u003eThe BKT.136 tie-plate kit ships with the CS136MH, and the BKT.FLR floor bracket (sold separately) anchors the stack.
