K-Array Pinnacle KR402P II – Passive Stereo Line Array System

Product Overview

The K-Array Pinnacle KR402P II is a passive stereo line array system engineered for commercial AV installations that demand high output from a visually discreet footprint. The system pairs four Python KP102 I stainless steel line array elements with two Thunder KS3P I passive 21" subwoofers, all driven and processed by a single Kommander KA104 four-channel DSP amplifier. For integrators specifying a house of worship sound system, auditorium reinforcement, or a multi-purpose room audio installation, the KR402P II delivers full-range stereo coverage with the slim column profile K-Array is known for. Mounting hardware is included, so the package arrives deployment-ready for permanent installation.

Product Description

Each Python KP102 I element is a meter-long, stainless steel column loudspeaker loaded with twelve 3.15" neodymium magnet transducers. The closely spaced drivers produce the long throw and high speech intelligibility characteristic of a pure line array, with controlled 7°–30° vertical dispersion and a wide 90° horizontal pattern that keeps energy on the audience and off reflective ceilings and walls. Stacking two KP102 I elements per side extends vertical pattern control for medium to large rooms.

Low-frequency support comes from two Thunder KS3P I passive subwoofers, each built around a long-excursion 21" neodymium woofer with a 4" voice coil in a compact, lightweight enclosure. The included Kommander KA104 amplifier platform supplies 4x 2500 W at 4 ohms with onboard DSP and factory presets matched to the KP102 I and KS3P I, so system tuning starts from a verified baseline rather than a blank slate. Remote control is available through the K-array Connect mobile app, while K-Framework3 software manages multiple units over wired LAN for larger projects. Because the loudspeakers are fully passive, all electronics live in the rack, simplifying service access in installed environments.
