The oh-so-aptly named Laocoon Loudspeaker/Follyphone. Photo circa 1912. (A fake instrument designed by Mr Lewis Sydney (pictured) to poke fun at the elaborate experimental musical instruments being invented at the time).

Moving somewhere in the uncertain middle ground between loudspeaker and church-organ, the Amplifier Institute Laocoon Loudspeaker was a demanding example of interactive audio technology. Every Thiele-Small parameter, and quite a few others, could be manipulated in real time for the optimal musical experience. Note the user/victim shown here has been obliged to use his left foot to control No 4 Bass Damping Control lever. Note also that he is raising his eyes to heaven, as well he might. Students of classical literature will understand the name Laocoon borne by this snappy bit of technology.
