Overview
The LF- 2215 dual 15-inch (381 mm) low-frequency enclosure is designed specifically to address the extended low-frequency response required for cinema applications. The LF-2215 covers the frequency range from 35 Hz to 300 Hz. Close Coupled Woofers (CCW), with their tight spacing between woofers, improves coupling.
The SC-223 is designed for ease of installation. The MH-1060 components come pre-assembled to reduce field assembly time. Three bolts are all that are required to secure the MH-1060 to the top of the LF-2215 enclosure.
Features
- 3-way bi-amplified screen channel system
- MH-1060 provides 90° horizontal by +20° to -30° vertical coverage
- LF-2215 is constructed of MDF and is heavily braced
- Low-distortion waveguides provide highly articulate dialogue
- Shallow depth (20-inch) facilities installation
