The Conn pipe speakerswere constructed with either two or four 6" x 9" speakers in the pipe chest which fire up through the bottom of the pipes. According to Conn literature, the sound from the speakers excites the column of air in the pipes, which are apparently tuned to appropriate pitches, so a more-or-less "pipelike" sound emanates from the top of the pipes, and there is a slight bit of sustain (reverb?) to the sound after a key is released as the sound within the pipes dissipates. Ihave three sets of them connected to a modern digital organ. My personal opinion is, they probably enhanced the sound of the 70s-80s organs they were paired with. Current digital organs, maybe not quite so much, but I do like what they do to higher pitched reeds, strings,and mixtures, giving them a brilliance ordinary speakers don't have. Whether one likes the sound of them is a matter of taste, I suppose, but many people like them. I doubt you could go wrong. And of course, the main reason I bought them was for the "look."
