K-array Lyzard KZ1 I — SPL & coverage

The Lyzard KZ1 I is rated 86 dB SPL at 1 m. Sound pressure falls with distance under the inverse-square relationship, so at 6 m and full output the planner shows roughly 70 dB; wound back to a 50% drive setting for background dining use, that becomes approximately 67 dB at the listener — headroom intact, nothing straining.

The cabinet's 140 deg x 140 deg (H x V) dispersion is unusually wide for a point source, which is what produces the approximately 16.5 m horizontal coverage radius on the -6 dB axis. A wide, symmetrical pattern favours even near-field fill across tables close to and away from the cabinet rather than throw down a narrow corridor. Being a passive cabinet, the Lyzard KZ1 I needs matched external amplification sized to the room and programme material — it has no onboard power stage.

In the planner, drag the listener-distance and drive-level controls to watch the reported SPL move in real time. The box-count figure the planner returns is a front-coverage area estimate only; treat the SPL-at-listener figure as the separate feasibility check for whether the level is actually adequate at that seat.

The planner does not model room reverberation or RT60, so a hard-surfaced dining room will read louder in practice than the free-field figure shown here. It also does not handle zoning across distinct areas (bar vs dining vs patio), subwoofer pairing for low-frequency extension, the mechanical rigging of a cabinet array, or DSP/delay tuning between multiple boxes — all of these sit downstream of this coverage estimate.
