Yes. A number of the early designs in QST (decades ago) were straight sections.
If you want to play around with the tube, pick up a couple of long "mailing tubes". They are cardboard, so not quite as acoustically efficient I suspect, but easy to trim and fiddle with to determine what length you want to make out of harder material. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of P.J.Hicks Sent: Friday, February 17, 2017 10:57 AM To: ELECRAFT Subject: [Elecraft] (OT) CW Resonant Speaker Has anyone built the resonator with a straight length of tube? Perhaps terminated with a 45 deg. cut? Might be an interesting experiment. The 45 deg long radius street elbow in 2" is an order only item in my area so thought I'd substitute a straight length.
