The CCA house sound, by the numbers
Across the 19 measured models, the most common tuning is bass-heavy (4 of 19, 21 percent). Next most common: bright (4), warm (3).
The model that needs the least correction is the Trio, with no band more than 1.7 dB from neutral. The one that needs the most is the A10, off by up to 5.0 dB before EQ.
