Have my speakers blown? Advice please

[Steelmonkey]

Hi, I've an aging Jamo DVR50 cinema system with Jamo A305 speaker system. All have worked nicely for many years. Recently I've started to hear a sort of buzzy distortion on two of the speakers at specific frequencies. Piano music seems to be the main culprit. Have these speakers "blown" and what could I do to fix or improve things please? Many thanks

I would swap speakers around to see if the distortion moves with the speakers if so I would invest in a new set Richer sounds do a wide range from not a lot of money

Thanks I'll try that. Can't understand how it's happened though. I never push them volume wise
