K1 3-Way Active Dual 15 Line Array Speaker System – High-Performance Audio for Professional Sound Reinforcement

The K1 3-way active dual 15 line array speaker system delivers precision-engineered acoustics and robust build quality tailored for live sound applications, touring productions, and permanent installations. Designed with a focus on clarity, coverage, and durability, this professional-grade loudspeaker combines advanced wavefront shaping technology, multi-driver architecture, and intelligent DSP control to ensure consistent performance across diverse environments. Whether you're managing large-scale events or small venues, the K1 offers reliable audio reproduction from deep bass to high-frequency detail—making it an essential tool in any modern sound engineer’s arsenal.

Key features include a wide usable bandwidth of 35 Hz to 20 kHz (-10 dB), ensuring full-range fidelity for music, speech, and effects. With a maximum SPL of 147 dB, the system excels in demanding acoustic conditions without distortion. The unique 110° horizontal directivity pattern (symmetrical) and customizable vertical dispersion provide precise sound coverage tailored to room geometry and audience layout. Its modular rigging design supports inter-enclosure angles from 0.25° to 10°, enabling flexible array configurations that maintain coherent wavefronts even in complex setups.

Internally, the K1 houses two 15-inch low-frequency drivers in a bass-reflex enclosure, four 6.5-inch midrange units with dedicated reflex loading, and three 3-inch diaphragm compression drivers equipped with individual DOSC® waveguides for optimized high-frequency dispersion. This tri-band configuration ensures seamless crossover transitions and uniform tonal balance across all frequencies. Each driver section is powered by a dedicated channel within a quad-amplifier shell featuring 4 x 1800W output at 4 ohms, delivering ample headroom for dynamic peaks while maintaining thermal stability through built-in protection systems. The integrated digital signal processor operates at 96 kHz sampling rate using 32-bit floating-point precision, allowing for ultra-accurate filtering, delay compensation, and real-time monitoring via Ethernet-based remote control protocols.

Constructed from premium Baltic birch plywood with die-cast aluminum side panels and corrosion-resistant steel rigging hardware, the K1 withstands rigorous touring demands. Its IP55-rated cabinet provides dust and water resistance, making it suitable for outdoor stages and temporary installations. The sleek dark grey brown finish (Pantone 426 C) not only enhances visual appeal but also blends seamlessly into most stage environments. With a net weight of 56 kg and dimensions of 438 mm H × 520 mm D × 1342 mm L, the unit balances portability with structural integrity—ideal for both mobile and fixed installations.

This active line array speaker is ideal for use in concert halls, clubs, corporate events, festivals, and theater productions where consistent sound coverage, high output capability, and reliable operation are critical. Its compatibility with Subwoofer extensions allows for extended low-end response down to 25–34 Hz, enhancing immersive audio experiences for EDM, hip-hop, classical, and spoken-word performances alike. Engineers appreciate the intuitive user interface, comprehensive preset storage (199 locations), and AES/EBU digital input options that simplify integration into modern digital mixing workflows.

Users consistently praise the K1 for its transparent midrange clarity, tight bass response, and ease of setup in both single-box and stacked array configurations. Many report improved audience engagement due to the system’s ability to deliver even coverage over long distances without audible coloration. The inclusion of real-time diagnostics for gain, mute, EQ, and load monitoring makes troubleshooting effortless during live shows, reducing downtime and increasing operational efficiency.

Common questions often revolve around compatibility with existing amplification systems—though the K1 includes its own powerful internal amplifier, it can also be used as a passive component in larger arrays when paired with external amps. Another frequent inquiry concerns the optimal stacking angle for different venue sizes; recommendations range from 1° to 5° for smaller rooms and up to 10° for large open-air events, depending on desired coverage width and height. Maintenance is minimal thanks to the durable construction and protective circuitry, though regular cleaning of grilles and inspection of connectors are advised for sustained performance.
