Core Design: 3-Way Column Loudspeaker

The KC12 uses a true 3-way active design, combining:

• 12-inch subwoofer for low frequencies
• Midrange drivers for vocal clarity
• High-frequency compression driver for detailed highs

This separation ensures:

• Strong bass response
• Clear and present vocals
• Wide and even sound dispersion

Unlike traditional PA speakers, the column design improves coverage consistency across the listening area.

Power & Amplification

The system is powered by a high-efficiency Class D amplifier module, delivering a total system power of up to 1450W peak output.

Performance highlights include:

• High headroom for live performance
• Clean output at high SPL levels
• Low distortion even under heavy load
• Efficient thermal management for long sessions

This makes it suitable for both indoor and outdoor professional use.

DSP Processing & Sound Tuning

The KC12 includes advanced built-in digital signal processing (DSP), allowing optimized sound performance depending on the application.

DSP features include:

• Factory-tuned EQ presets
• Dynamic limiting protection
• System alignment processing

Coverage & Dispersion

One of the strongest features of the KC12 is its wide and controlled coverage pattern.

It provides:

Subwoofer Performance

The integrated 12-inch subwoofer delivers deep, controlled low-frequency output.

It provides:

• Tight bass response

This eliminates the need for an external subwoofer in many setups.
