[. . . ] A high power 10" cone driver allows operation as low as 250 Hz and the advanced phase plug coupling permits a crossover point of up to 1800 Hz to the high-frequency horn. This ensures that most of the dialog range is reproduced by a single element for unmatched intelligibility. The LF-4115 single 15" (381 mm) low-frequency enclosure is designed specifically to address the extended low-frequency response required for cinema applications. The LF-4115 covers the frequency range from 35 Hz to 250 Hz. The SC-413 is designed for ease of installation. The MH-1063 components come pre-assembled to reduce field assembly time. Three bolts are all that are required to secure the MH-1063 to the top of the LF-4115 enclosure.
