Evidence update · 1 September 2026

Catalog 4.31.64, checked 26 October 2026, contains 26 SMSL product records: 25 deep profiles and 1 additional searchable record. All 26 are L2 documentation profiles; this does not claim independent SPL testing. Similar model names and rapid revisions mean the exact suffix, driver, remote and firmware file must be verified before transferring a specification between products.

Manufacturer output and distortion figures remain manufacturer claims until a traceable independent measurement is attached. Future QA403 results will be added as separate measurement records.
