Pi H290C OSEC Waveguide Amplitude Response

Some of the measurements for the H290C and H290 are posted. These are unsmoothed curves taken one meter from the horn in-room. The top and third plots are the H290 and the second and fourth are the H290C. Notice in particular the lower third (red) and fifth (magenta) harmonic distortion for the H290C. The response is also a bit smoother and there is no rise in the higher frequencies that most likely represents the crossover modifications.
