It uses a dual-entrant asymmetrical horn driven by a 2-inch composite-diaphragm mid-frequency compression driver and a 2-inch HT polymer high-frequency compression driver. Mounted on a CS136LF low-frequency cabinet, it forms a screen channel for medium and large auditoriums.\u003c\/p\u003e\n\n\u003ch2\u003eHow does the Dolby CS131MH work?\u003c\/h2\u003e\n\u003cp\u003eThe dual-entrant horn lets the MF and HF drivers sit close together, which improves pattern control around the crossover frequency. Its asymmetrical pattern spans 55° at the top and 100° at the bottom horizontally, with 50° vertical, so coverage and volume shading stay even across the seating area. Frequency range is 400 Hz to 20 kHz.\u003c\/p\u003e\n\u003cp\u003eThe CS131MH runs in passive mode at 8 ohms, rated at 300 W @ 49 Vrms with 103 dB sensitivity and 128 dB continuous SPL at one metre. In bi-amp mode the MF and HF sections take separate 8-ohm channels (80 W and 70 W) for 130 dB continuous output. The advanced input plate's high-current, spring-loaded terminal block allows tool-free connection, and the horn ships preassembled.\u003c\/p\u003e\n\u003cp\u003eTilt and pan mechanisms speed aiming during commissioning.
