Model 8C10DVCA-2T72 is a premium pro sound, 8-inch 15W single cone driver with dual voice coils and two transformers, designed for systems where individual speakers must be connected to two separate or piggy-backed systems and is typically used for retrofit applications. Order grille and enclosure separately. Important: Do not use this driver if one voice coil is fed from a local or zoned sound system because it would result in cross-talk issues. An application like that would require two separate speaker drivers.

Specifications

• Driver:  8 in. 15W cone speaker with two voice coils allows for mechanical mixing of two circuits, such as music and paging, at the speaker. Highly efficient magnetic structure energized by 10oz ceramic magnet.
• Frame:  20-gauge stamped steel with zinc-plated finish.
• Mounting Bolt Circle:  7.625 in.
• Transformers (2):  25V/70V dual voltage transformers with taps at .25, .5, 1, 2, 5W
• Assembly Frequency Response: 54Hz-9kHz (±6dB), 50Hz-20kHz (±13.4dB)
• Assembly Mounting Depth:  2.84 in.
• Assembly Dispersion Angle:  90 degrees conical
• Assembly Average Sensitivity:  95.8dB
• NOTE: Dual voice coil speakers should not be used when one voice coil is fed from a local (or zoned) sound system. For example, an application where a dual voice coil speaker is installed in a classroom with one voice coil connected to the school’s all-call paging system and the other voice coil connected to a local sound system that is used only in that classroom. When the local sound system is playing, the all-call voice coil will also be traveling across the speaker’s magnet which induces a small cross-talk voltage on the all-call speaker line. In the speakers in all other classrooms that are connected to the all-call speaker line, this will result in the audio from the local classroom sound system being heard softly. Only use dual voice-coil speakers when all of the speakers on the line are fed by the same two all-call amplifier systems.
