It combines a custom 12-inch mid-frequency driver with a low-distortion 75 mm titanium dome high-frequency driver on Dolby's patented asymmetrical waveguide. Mounted on a CS128LF low-frequency cabinet, it forms a complete screen channel for medium-sized immersive auditoriums.\u003c\/p\u003e\n\n\u003ch2\u003eHow does the Dolby CS128MH work?\u003c\/h2\u003e\n\u003cp\u003eA passive crossover inside the cabinet splits the signal between the 12-inch woofer and the titanium dome, so one amplifier channel drives the CS128MH. When it is paired with the CS128LF to form a System 128, the stack needs a minimum of two amplifier channels.\u003c\/p\u003e\n\u003cp\u003eThe asymmetrical waveguide covers 60° at the top and 120° at the bottom horizontally, with 60° vertical. Rear seats receive more direct energy while front rows get wider, softer coverage, which keeps dialog level consistent. The 12-inch driver uses a cooling-optimized motor and suspension plus an aluminum demodulation ring for lower distortion, and convective vents cool the HF driver and crossover.\u003c\/p\u003e\n\u003cp\u003eRated at 300 W @ 49 Vrms into 8 ohms with 101 dB sensitivity, the CS128MH covers 255 Hz to 20 kHz and reaches 126 dB continuous and 138 dB measured peak SPL at one metre.
