The loudspeaker system shall be 3-way actively driven between the low frequency and the mid/high sections. A passive crossover shall be used between the mid/high frequency sections.

The loudspeaker shall only be operated by a dedicated, compatible controller amplifier.

The loudspeaker shall produce a cylindrical wave segment suitable for use as an element in a line array and maintain an extremely accurate horizontal dispersion pattern down to very low frequencies (80° > 250 Hz).

The loudspeaker shall have a design that exhibits extremely low power compression and for this reason shall utilize the rear rigging elements as a heat sink for the midrange driver.

The loudspeaker shall consist of two 12" LF neodymium drivers in a vented enclosure, one hornloaded 10" midrange driver and two coaxially mounted 1.4" exit compression drivers with 3” voicecoils coupled to a waveshaping device.

The enclosure shall be constructed from marine plywood with an impact resistant and weather protecting PCP (Polyurea Cabinet Protection) finish. The cabinet front shall be protected by a perforated steel grill backed with acoustic foam.
