Powerful 15-Inch Sound

The KL 15 combines a 15-inch low-frequency driver with a 2.5-inch voice coil and a 1-inch high-frequency compression driver with a 1.35-inch voice coil. The two-way configuration is designed to provide powerful bass response while maintaining clear and detailed high frequencies for music, speech, and live performance.

With an 800W peak amplifier and maximum SPL of 128dB, KL 15 provides the output required for demanding live applications while remaining suitable for portable sound systems.

Advanced DSP with Linear Phase FIR Filters

KL 15 uses advanced DSP processing with Linear Phase FIR filters to help maintain a coherent phase response and consistent sound across different listening positions. This processing contributes to the system's clarity and intelligibility while providing practical control over the speaker's tonal response.

Four built-in presets are available: Playback, Flat, Bass Boost, and Wedge. These settings allow the speaker to be quickly adapted for music playback, general sound reinforcement, enhanced low-end performance, or stage-monitor applications.

Flexible Three-Channel Input Section

The KL 15 provides three independent input channels for flexible source connection. Channel 1 features a balanced XLR/6.3mm combo input with selectable microphone or line operation, making it suitable for microphones or line-level equipment. Channel 2 provides a balanced XLR/TRS input for an additional line-level source.

Channel 3 includes a built-in Bluetooth receiver, allowing compatible mobile devices and wireless sources to be connected without an additional cable or external receiver.

LINK and MIX Output

A balanced XLR-M output provides flexible signal distribution to additional equipment. The output can be switched between LINK and MIX operation. LINK sends the signal before the individual level controls, while MIX follows the channel and Main level controls, allowing the KL 15 to feed another loudspeaker or mixer according to the requirements of the setup.

Stage Monitor and Pole-Mount Operation

The cabinet is designed for more than conventional front-facing PA use. Its symmetrical 45° rear inclination allows the KL 15 to be positioned as a stage monitor, while the 36mm pole-mount socket offers two tilt positions of 0° and 7.5° for flexible tripod and stacked configurations.

The 90° × 60° dispersion pattern provides broad horizontal coverage with controlled vertical coverage, making the KL 15 suitable for audiences, performers, and small venue sound reinforcement.

Portable and Practical Cabinet Design

The KL 15 uses a rugged polypropylene enclosure with a full front grille and three integrated handles: two side handles and one top handle. These features make transportation and positioning easier for mobile performers and sound technicians.

The speaker is supplied with a dedicated soft cover featuring a purpose-designed pocket for cable storage, providing additional protection during transport and keeping essential cabling conveniently with the loudspeaker.
