One problem, IMHO, with the panasonics is the size of the hole in the
front. It is too small and can reverberate under extremely loud sound
pressure levels.
If you can make something with a larger diameter hole it would be great.

Someone here, I think perhaps it was Seigfried back when he
was a contributer, calculated the resonance of the Helmholtz
resonater that the cavity and hole comprise and found it to
be well above the audio band. Enlarging the hole could even
possibly lower it.
Larger hole == higher resonance; smaller hole == lower resonance frequency.
Diffraction effects might have more influence on HF performance -- dunno.
