could be, but realistically, you want to use the speaker drawing the horizontal line at the max bass /treble distortion (whichever lower ) you could accept and use that as the max level you could use it to not causing the music to distort above the SPL, KH150 is very capable but then in reality, the S360 in bigger rooms might make more senseright, so above 1,5kHz KH150 tweeter is even better than s360s compression driver, what a bargain
