11/28/2020 added 6" waveguide

6/20/2021 updated design with new tweeter interface, does not impact performance

9/1/2021 added 6.5" vA 68

note: the spike near 48khz in the plots below is probably an artifact of the sound card cutoff doing wonky things with the FFT math

5" waveguides

note: 5" 68 vA is an elliptical mouth with an aspect ratio of 1:.68
