A dual-entrant asymmetrical horn with 2-inch compression drivers sits on a dual 15-inch LF cabinet. The system covers 31 Hz to 20 kHz with 28 Hz usable response and 134 dB maximum summed continuous SPL.\u003c\/p\u003e\n\n\u003ch2\u003eHow does the Dolby System 131 work?\u003c\/h2\u003e\n\u003cp\u003eThe CS131MH uses a dual-entrant asymmetrical horn that places its mid- and high-frequency compression drivers close together, which improves pattern control around the crossover and gives even coverage and volume shading. Coverage spans 55° at the top and 100° at the bottom horizontally, with 50° vertical. A composite-diaphragm 2-inch mid-frequency driver and an HT polymer 2-inch high-frequency driver handle the upper bands.\u003c\/p\u003e\n\u003cp\u003eThe CS131MH runs passively at 8 ohms (300 W @ 49 Vrms) or bi-amped with separate MF and HF channels. The CS136LF carries two 15-inch woofers rated at 1400 W @ 74.8 Vrms and wires at 4 ohms or 8 ohms through its flip-card input. Spring terminal blocks on the advanced input plates allow tool-free connection, and the preassembled horn simplifies setup.\u003c\/p\u003e\n\u003cp\u003eIntuitive tilt and pan mechanisms aim the horn at the seating area.
