Sadly both volti,as well as Any Klipsch speakers use at best average parts quality
out a 15 rating maybe 8, which is just being cheap for an extra $400
you can have far more premium parts ,I have rebuilt Xover for over 20 years
and over 85% keep making the same mistakes ,which is the ♥️ of all loudspeaker system and dictates it’s tonal balance as well as integrity.
