Tikandi Measurements

I measured the Tikandis and my own speakers using my Earthworks microphone and Spectra Plus FFT software. Frequency response measurements were made using a white noise signal played at 100 dB SPL at 1m distance. Measurements were made both at 1m distance and at the listening position.

Frequency response was measured at 1m on axis (top), and at the listening position (bottom). On axis, frequency response was within a few dB above 100 Hz, with bumps below 100 Hz. Room correction was calculated for the listening position, not on axis at 1m. The suckout just below 500 Hz is a room effect, and was not able to be corrected accurately due to the sharpness and the fact the frequency changes depending on the microphone position. At the listening position, the bass was much smoother, but the higher range was a bit more lumpy. Still, the frequency response was very flat compared to a typical loudspeaker.

1 kHz (top) and 10 kHz (bottom) sine waves showed 0.3 and 0.6% THD. This is a ridiculously low THD level for a loudspeaker. It would be reasonable for an amplifier much less a loudspeaker.

Gallo Measurements

Frequency response of the Gallos was also measured at 1m on axis (top), and at the listening position (bottom). These measurements were actually flatter than the Tikandis. I believe this is because I set up, listened to and measured my speakers second, giving me more time and experience to set up, measure and adjust the speakers. The measurements shown here were for the "hybrid" mode I found to sound the best.

The 1 kHz sine wave showed 1.2% THD, 4 times higher than the Tikandis. I did not measure the 10 kHz sine wave with the Gallos.
