You have to read what a patent is about. Sometimes it's not evident. The Dahlquist patent for the DQ 10 is a great case in point. Given it's design and hoopla one would assume it was for the time alignment of the speaker. It wasn't. The patent was for the iron angles bent at 90 degrees used to hold the individual panels on. I was shown the patent by a friend who had a patent attorney for some tube/FET combinations. His attorney looked up the Dahlquist patent for him. It blew my mind when I saw the real patent. I wonder how many times this kind of thing has occurred. By the way I don't mean this to be any comment on the Dahlquist's performance.
