The K-Array KR402 Mark I Powered Stereo System includes a pair each of KMT21 Mark I 21" Subwoofers, KY102K Bundles, and KY102KF Bundles.
The KMT21 Mark I Powered Subwoofer features a 21" direct-radiating, long-excursion driver, programmable on-board DSP, and multiple analog & digital I/O for creating a broad range of speaker configurations. Equipped with a codec that lowers the signal/noise ratio, the KMT21 Mark I Subwoofer offers enhanced functionality for creating presets. It also features an integrated touchscreen that provides intuitive control over the main DSP functions including input/output levels, signal routing, offset delays for subwoofer and speaker output (up to 10 ms, each) and overall system delay (up to 330 ms).
Each KY102K Bundle includes a Kayman KY102 Line-Array Element Speaker and K-Joint2 Adapter, which come packaged in a carrying case. The KY102KF Bundle is similar to the KY102K, but with a K-Foot2 Column-Installation Adapter included. A pair of KY102 Line-Array Element Speakers, connected via the K-Joint2 Mounting Adapter, stand atop each KMT21 Mark I Subwoofer utilizing the K-Foot2 Adapter and an extension pole (not included).
The KY102 Line-Array Element Speaker features eight 4" long-excursion, full-range cone drivers housed in a sturdy stainless steel chassis. The closely-spaced drivers feature true line-array characteristics, such as phase coherence, low distortion, and focused listening in both the near field and at a distance from the speaker. The speaker is able to reproduce the whole vocal frequency range with high intelligibility, starting from 90 Hz.
