Bravo to Vicky for discovering the need to bass boost the signal before feeding the Pleiades Linoleum Auratone type 5C speaker

One way to do this is mid, treble cut between amplifier and speaker. Current experimental values for a very nice balanced sound with great articulate, deep bass is (taking jumper cables into account), (amp now sees 12.8ohms instead of 4ohms): A series resistor of 10ohms. A (2.3ohm resistor in series with 220uF capacitor) shunt to jumper cables, cables feeding Tesla drive unit.
