I wouldn’t say I’m an expert, well with resonators anyway, and this is very much an experiment so we shall se. When talking to more experienced reso builders than me, they all said about adding ports. Like you say I’ll find out when it’s all together. I have heard it prior to doing this so it will be interesting to see how it sounds.

You are kind of wrong but your logic is sound. It’s a little different for a reso. They act a bit like a speaker but l not really. The cone kind of vibrates back and forth, rather than moves back and forth as much as a speaker. They do get their tone from the back of the cone. If you look at a resonator the f holes or holes near the cone are put in for this very reason of letting the sound and air from the rear of the cone escape. This helps it not sound choked, a bit like a port on a speaker. Some national electric resonators have a cover plate on the back as well as the front.

Like it.

Late idea…I’ve drilled holes deeper than where the cone sits. This allows air from behind the cone to come out through the front, this should make its acoustic sound even better and also help to make it a little louder.
