- 50w Power Handling
- 84.5db Efficiency
Below is the measured harmonic distortion spectrum for orders up to 9th harmonic and THD for 2.0Vrms at 0.5m. Distortion is very low and does not have anomalous resonances. There is a 670Hz bump that might be a woofer basket resonance, but it is quite low. Nominal distortion at 1khz is about 0.19%

Below are some measurements of the Vanguard Scout speaker response showing the crossover response curves. Crossover is my own asymmetric slope design employing 2 inductors, 2 capacitors, and 2 resistors. Crossover frequency is at 1700Hz with both drivers having absolute positive polarity for nice transients and percussion realism. Blue is predicted system response and orange is actual measurement overlay:
