You couldn't cross over the Beyma horns as low as the USD. Low-frequency cutoff is DIRECTLY affected by mouth size... half as big of a mouth, will restrict low-end output ONE OCTAVE higher. While the USDs are probably good to around 500 Hz, the Beymas are only good to 1000Hz, at the LOWEST. I'd probably not use something THAT small below 1200 Hz...
