  "description": "Per-category and per-brand counts of specification disclosure across all nine tracked home theater categories: loudspeaker sensitivity ratings with and without their measurement conditions, minimum-impedance disclosure, AV receiver power ratings with and without channels-driven and THD, subwoofer low-frequency extension claims with and without a dB tolerance, TV and projector VRR / ALLM / 4K input-lag disclosure, projection-screen gain with and without a half-gain viewing angle, media-player resolution claims with and without output frame rates, acoustic-treatment NRC ratings with and without the third-octave absorption coefficients behind them, and home theater seating weight capacity and per-seat versus total width. Recomputed from the live catalog; a value a manufacturer does not state is stored as a first-class 'unstated', never guessed.",
