Consumer protections? Electrical standards?
AS/NZS Electrical Standards, Canadian Safety Association, Federal Communications Commission, International Electrotechnical Commission, Japanese Electrical Manufacturers Association, National Electrical Code, National Electrical Manufacturers Association, National Fire Protection Association, Occupational Health and Safety, Underwriters Laboratories, etc.
I'm sure Celestion has to comply with standards to be able to sell their products. It's a 20 watt speaker to anyone with authority.
