The standard
Designed to the industry’s own benchmark.
CEDIA/CTA‑RP22 is the recommended practice for immersive audio in private cinemas, published by CEDIA and the Consumer Technology Association. It defines four levels of performance, judged where it matters: at the seats. How loud, how quiet, how even. Every AMP loudspeaker is designed to its targets.

The most that can be achieved
Minimum screen-channel level at the listening position, dB SPL(C). Source: CEDIA/CTA‑RP22 v1.2 (2023), Table A.1. RP22 levels describe a complete system in a room, so the level a cinema reaches depends on the room, the amplification and the layout as well as the loudspeakers.
