What about people who speak QSC?

QSC speaker is a high-power professional stage speaker made in America.

Professional speakers, namely stage speakers, are high-power speakers suitable for stage performances, singing, square concerts or publicity activities.

The sound quality of this speaker is good, but it is not suitable for home use-because it is not the sound quality of HiFi (the sound of professional speakers is rough-the midrange is good, and the bass and treble are almost the same), and the power is very high, which requires a large amplifier to make a good sound; If the power is reduced, the sound will be distorted and ugly.
