55 Hz – 18 kHz

Phase Response

92 Hz – 18 kHz ±30 degrees

Linear Peak SPL3

133.5 dB with 18 dB crest factor (M-noise), 130 dB (Pink noise), 134.5 dB (B‑noise)

COVERAGE

Horizontal Coverage

110°

Vertical Coverage

Varies, depending on array length and configuration

TRANSDUCERS

Low Frequency

Two 9‑inch long‑excursion cone drivers; 2 Ω nominal impedance

High Frequency

One 3‑inch diaphragm compression driver coupled to a constant‑directivity horn through a patented REM® manifold; 4 Ω nominal impedance

AUDIO INPUT

Type

Differential, electronically balanced

Maximum Common Mode Range

±15 V DC, clamped to earth for voltage transient protection

Connectors

XLR 5‑pin female input with male loop output; XLR 3‑pin female connectors available to accommodate only balanced audio (no RMS signals)

Input Impedance

10 kΩ differential between pins 2 and 3

Wiring4

Pin 1: Chassis/earth through 1 kΩ, 1000 pF, 15 V clamped network to provide virtual ground lift at audio frequencies

Pin 2: Signal + Pin 3: Signal ‑

Pin 4: RMS (polarity insensitive) Pin 5: RMS (polarity insensitive) Case: Earth ground and chassis

Nominal Input Sensitivity

6.0 dBV (2.0 V rms) continuous is typically the onset of limiting for noise and music

Input Levels

Audio source must be capable of producing +20 dBV (10 V rms) into 600 Ω to produce the maximum peak SPL over the operating bandwidth of the loudspeaker
