Voicing and Construction

Top bracing is 3 fan braces with a carbon fiber bridge plate. Back bracing is X-braced which allows easier tuning of back resonance. My experience is that the Chladni pattern is larger on the back when X-braced versus ladder braced.

Top thickness 2.0mm at center tapering to 1.6mm at perimeter.

Back thickness 1.9 mm thinned to 1.6mm at perimeter.


Top monopole 365 Hz

Top cross dipole 511 Hz

Top long dipole 703 / 785

Back 390 Hz

Air 190 Hz
