Sound Horn(s)

This is a little larger than we are aiming for but representational of our concept none the less... impression

Dimensions of a sound horn are generally as follows:

Length = 1 wavelength of lowest frequency to express

Circumference of open end = 1 wavelength of same lowest frequency

From that frequency the horn will be effective at sounding the next 3 octaves. A smaller horn is required for higher frequency sounds and therefore it follows that more than one horn may be required to adequately sound all frequencies of our 3D print interpretation...
