So here is the actual mesaured frequency reponse in Voltage dB at speaker terminals, Nice for a 300B I think,I love the sound but one cannot deny the frequency drop off of 1dB that must be audible.. the secondd figure is the inroom measurement with Tranistor(green) vs 300B (Blue) tube amplifier using a calibrated Umik microphone..
