On the Bench

At 50 Hz I could get 95 dB out of the speakers, but distortion was 27%. If you use these in your home theater, I would suggest a crossover frequency of 80 Hz.

At 1 kHz, the story is much different, with distortion at only 0.8%>

And, at 10 kHz, the speaker produced less than 0.2% THD+N, almost entirely 2nd order.

The THD+N vs. Frequency graph shows a reasonably flat spectrum across the audible band, staying below 1% distortion.

The quasi-anechoic frequency response was pretty flat from 63 Hz to 20 kHz. (Click on the graphic to enlarge it. Click on it again to return it to the smaller size.)

Although the nominal impedance is 8 ohms, it does dip down to 4 ohms. The spectrum suggests that this will be a relatively easy speaker for receivers to drive.
