Free-field model with one point source per stack, without ground reflection, audience absorption or cabinet response. Cardioid is approximated as a directivity pattern and does not reproduce any manufacturer preset; the choice of reversed cabinet is documentation only. Absolute levels are to be read as relative. Rating uses four frequencies across the working range. Check delays and gains against a second source before transferring them.
