Sound power alone does not predict loudspeaker sound quality.

Evidence

It also showed that sound power, what CU based its accuracy score on, was, by itself, not a good predictor of sound quality. However, when viewed as a member of the spinorama family of curves, irregularities in all of them indicated the presence of resonances, so the smoothness of the curve was relevant. — Toole, Floyd E, Sound reproduction- the acoustics and…, 1198
