It is hand-built from quality wood and uses two high-performance 15-inch transducers designed with Finite Element Modeling (FEM). Massive magnetic motors and cast-aluminum baskets give it low distortion and deep, faithful bass.\u003c\/p\u003e\n\n\u003ch2\u003eHow does the Dolby CS136LF work?\u003c\/h2\u003e\n\u003cp\u003eThe two 15-inch drivers use 4-inch copper voice coils, FEM-optimized motors and suspensions, cooling systems and resonance-free cast-aluminum baskets. Exceptional internal bracing and a finely tuned port design reduce distortion and support years of dependable service. The cabinet covers 31 Hz to 400 Hz with 28 Hz usable response.\u003c\/p\u003e\n\u003cp\u003eRated at 1400 W @ 74.8 Vrms with 102 dB sensitivity, a single CS136LF reaches 133 dB continuous and 142 dB measured peak SPL at one metre. The advanced input plate's flip card selects 4-ohm parallel wiring or 8-ohm bi-wire operation. In System 136 two cabinets stack, with the lower unit run under Dolby's separate processing values at 900 W @ 60 Vrms.\u003c\/p\u003e\n\u003cp\u003eBalance-centered handles, a shallow cabinet and a side-loading input plate make unpacking, installation and service easier.
