The EPZ house sound, by the numbers
Across the 13 measured models, the most common tuning is near-neutral (6 of 13, 46 percent). Next most common: warm (3), bright (2).
The model that needs the least correction is the Q1 Pro, with no band more than 0.5 dB from neutral. The one that needs the most is the 320, off by up to 5.1 dB before EQ.
