Measured directivity

Measured directivity is on file for this model through a proxy: the data was measured on the JBL M2. The Cinema Designer's reflections engine uses it in place of the coverage-angle model.

Note
JBL publishes no directivity for the SAM. The M2 shares the horn-loaded JBL Professional architecture. CEA-2034 comparison (internal comparison, 2026-02-11): listening window within 2 dB; the SAM beams about 2 dB more above 1 kHz, so the proxy slightly overstates wall energy.
