Professional-Grade Audio Performance
Multipurpose 2-Way System
The multipurpose 2-way system provides versatile performance for portable PA and fixed installations. The 2-way design is ideal for professional applications.
12" Woofer
The 12" woofer provides powerful and controlled low frequencies. The 12" size is standard for professional loudspeakers.
1.4" Titanium Diaphragm Compression Driver
The 1.4" titanium diaphragm compression driver provides clear and resilient high frequencies. Titanium is ideal for durability.
2000W Peak Power
Efficient Class D Amplifier
The 2000W peak Class D amplifier (1800W LF + 225W HF) provides exceptional power with energy efficiency. The power distribution optimizes low and high-frequency performance.
Flat Frequency Response
50Hz - 20kHz at -6dB
The 50-20kHz frequency response at -6dB provides flat reproduction across the audio band. A flat response is essential for accurate reproduction.
45-20kHz Extension at -10dB
The 45-20kHz extension at -10dB provides low-frequency extension. Extension is important for full-range reproduction.
132dB Peak Maximum SPL
Exceptional Sound Pressure
The 132dB peak maximum SPL measured on-axis at 1m provides exceptional sound pressure. A 132dB SPL is sufficient for most professional applications.
126dB Continuous
The 126dB continuous SPL provides sustained operation without distortion. Continuous SPL is important for professional operation.
Intrinsic Correction™ DSP
Automatic Intrinsic Tuning
Intrinsic Correction™ DSP provides automatic tuning and loudspeaker management. Intrinsic correction optimizes frequency response.
Loudspeaker Protection
Intrinsic correction protects the loudspeaker from overload and damage. Protection is important for durability.
Directivity Matched Transition® (DMT)
Excellent Power Response
DMT provides excellent power response throughout the coverage area. Power response is important for uniform reproduction.
75° Axisymmetrical Coverage
75° axisymmetrical coverage provides uniform dispersion. Axisymmetrical coverage is ideal for main PA applications.
Presets and Savable Scenes
Factory Presets
Factory presets for common applications allow for quick operation. Presets include options for PA, monitoring, and installations.
Savable/Recallable Scenes
Savable/recallable scenes allow for storing custom configurations. Scenes facilitate consistent operation.
Multi-Function LCD Screen
Intuitive Digital Control
The 1.75" x 1" multi-function LCD screen allows for control of crossover, EQ, delay, and frequency contour. Digital control is important for professional operation.
Multiple LED Indicators
Multiple LED indicators (power, input signal, limiter active) provide visual feedback. Indicators facilitate operation.
Versatile Professional Inputs
2x XLR Combo Inputs
The 2x XLR combo inputs allow for the connection of microphones and instruments. Combo inputs are standard on professional equipment.
3.5mm Stereo Input
The 3.5mm stereo input allows for the connection of portable devices. The 3.5mm input is ideal for phones and tablets.
XLR Loop-Thru and Mix Outputs
The XLR loop-thru and mix outputs allow for connection to additional systems. The outputs allow for daisy-chaining and mixing of speakers.
Robust Professional Construction
Impact-Resistant ABS Enclosure
The impact-resistant ABS enclosure provides durability. ABS is resistant to environmental conditions.
Dual Pole Cup Mounts
The dual pole cup (standard and 7.5° down-tilt) allows for flexible deployment. Pole cups are standard on professional equipment.
M10 Inserts for Flown Applications
The M10 inserts allow for flown mounting. M10 inserts are standard on professional equipment.
