This was done to test whether 12Ω would sound louder than 4Ω since the Pleiades BD139 power amplifier without no feedback impedance must be much higher.
It did sound about 2.5 times louder.
Almost as loud as the Zeis Ikon 12Ω baffle speaker.
All 3 Tesla speakers were in closed small boxes. One box of linoleum, the standard reference, the other ones made of cardboard.
