Subliminal Talk

Ok to listen to Ultrasonic and Music through same (quality) speakers? Or should the signal be the subliminal ONLY.

I've been listening to mostly the Hybrid, of OFv2, Loudly

but sometimes I want to also listen to some track or something --- At these moments ok to switch to Ultrasonic and run both? Unclear on this.

As long as the speaker is actually playing both at once, it's fine.
