PWK tired of the wild claims by competitors and took them to task at trade shows and snail mail. Eventually he simply put a Bullshit button inside the lapel of his jacket. When he heard bogus claims he just gave them a flash and walked off. This isn't very surprising as PWK would also discuss issues with his ministers after church if he felt they were wrong. There are some great stories about PWK at Church.
This is the straw that broke the camels back the Karlson. It was advertised flat + - 2db from 20hz to 20,000hz in 1955. Klipsch bought a Karlson and measured it at Hope. The results of course show that they earned a BullShit button and far from as advertised. I'm sure Jim Hunter at Klipsch has the correspondence between PWK and Karlson. I'd love to read those exchanges.
