Vertical Coverage Settings: Coverage is effective (frequency response similar) beyond the traditional -6 dB coverage angles. This is especially useful in
compensating for differences in listening distances. Figures show both the -6 dB and -12 dB coverage angles (at 3 kHz).
Angles are in reference to cabinet aiming axis.
Pattern UP Settings:
“Point”: -6dB @ +7°, -12 dB @ +12°
“Tight”: -6dB @ +9°, -12 dB @ +15°
“Narrow”: -6dB @ +10°, -12 dB @ +20°
“Medium”: -6dB @ +13°, -12 dB @ +24°
Pattern DOWN Settings:
“Point”: -6dB @ -7°, -12 dB @ -12°
“Narrow”: -6dB @ -10°, -12 dB @ -20°

Transducers:
Low Frequency Drivers: 6 pcs, 165 mm (6.5 in) drivers, lightweight neodymium motors, 50 mm (2.0 in) diameter voice coils, copper-capped pole
tips to minimize ux modulation and linearize inductance, 16 mm (0.63 in) long coil for high linear drive and high power
handling, damped blended textile surround, coated cones for moisture, UV and salt resistance. Magnetically shielded.
High Frequency Drivers: 24 pcs, 25 mm (1 in) drivers, neodymium, encased magnet and coated diaphragm for moisture, UV, and salt resistance.
