[Elecraft] K2 Internal Battery

I think a pipe with a speaker in the end is considered a closed end cylinder, but I am not completely sure.  If so, resonant lengths are shorter.  Here is the page from one of my favorite websites if you are interested in experimenting with resonant speakers:

Re: [Elecraft] (OT) CW Resonant Speaker

I have not but you certainly can do it. The length of the tube will determine the peak resonant frequency and you would have to experiment with the length to tune it to the pitch you like best to listen to. Remember the days you would blow across a bottle to make a tone? The more you drank out

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
