K-array Python KP102 I: SPL & Coverage

The Python KP102 I is rated at 134 dB maximum SPL at 1 m. Sound pressure falls off with distance under the inverse-square relationship, so at 15 m and full output the estimate drops to roughly 110 dB; pulled back to a 60% drive level for headroom and comfort, the estimate is roughly 108 dB at the listener position.

The cabinet's 90 degree x 30 degree (H x V) nominal dispersion is what sets the estimated 15 m horizontal coverage radius used here. The wide horizontal pattern spreads energy across the room width, while the comparatively tight 30 degree vertical pattern keeps throw controlled and reduces reflections off the ceiling and floor. As a passive cabinet, the KP102 I depends on a matched external amplifier channel sized to its rated power handling.

Inside the planner, drag the listener distance and drive level sliders to see the estimated SPL move in real time against the rated 134 dB @1 m figure. The box-count read-out is a front-coverage estimate based on dispersion and room width; treat SPL adequacy at the listener position as a separate check from box count, since a single cabinet can cover a wide area yet still fall short on level at the back row.

The planner does not model room reverberation or RT60, so highly reflective finishes will affect intelligibility beyond what the SPL figure alone suggests. It does not zone coverage across separate seating areas, pair the cabinet with a subwoofer for low-frequency extension, account for array mechanical rigging and cluster angles, or apply DSP delay and equalisation tuning — all of which belong in a proper acoustic design pass.
