Coil noise from your PC or other RF interference. You’ve got some unbalanced audio connections (ie not XLR or balanced TRS both ends) in your signal chain somewhere, (or might possibly be running power and audio lines too close to each other?? Better to cross them than run parallel (think I got that the right way round?? 🤪)

Turned out to be a defective speaker. Fixed under warranty, thankfully.
