K-array Vyper KV102 II — SPL & coverage

The KV102 II is rated 120 dB SPL at 1 m. Sound pressure falls off with distance under the inverse-square relationship, so at 15 m and full rated output the model shows approximately 96 dB; backed off to a 60% drive level for headroom, that comes down to approximately 94 dB at the listener.

The cabinet's 140 deg x 7 deg (H x V) dispersion is asymmetric by design: the wide 140 deg horizontal spread is what produces the approximately 41.2 m horizontal coverage half-width used in this preset, while the tight 7 deg vertical pattern keeps energy off the ceiling and floor, controlling throw down the room and reducing reflected sound. As a passive cabinet, the KV102 II needs a matched amplifier channel sized to its rated input; the planner does not select or size that amplifier.

Use the planner by dragging the listener distance and drive-level controls to see the SPL figure move in real time. The suggested cabinet count is a front-coverage estimate based on the horizontal dispersion angle and room width; SPL adequacy at the furthest listener is a separate check the planner runs alongside it, and both should read acceptable before treating a layout as workable.

The planner does not model room reverberation or RT60, coverage zoning across separate seating or lobby areas, subwoofer pairing for low-frequency extension, the mechanical rigging or flying of the array, or DSP/delay-line tuning between cabinets. Each of those is a separate design step that follows once the SPL and coverage basics for this cabinet are established.
