Default Sound Port Review Part #3

Pushing the design of sound ports I have become more daring in my work.



Another thing I've learned is the an intricate sound port design with a pattern of smaller holes performs more like a speaker grill than a bunch of tiny sound ports. The overall dimension of the design is what sound waves hit. The small holes don't act like a sieve only letting the highest frequencies through.



More recently I re-topped a Cocobolo Greta to set it up as a finger style instrument for Erithon. A sound port was requested. Erithon asked that we do a row of smaller sound ports in the similar to the inlay patterns on the arm rest and rosette. The challenge on this was just how small and how tight you can round the corners on the binding inside a very small sound port.







The answer is pretty tight!

That brings me up to date on the evolution of my sound ports.

Thanks for following along!
