Popping Noise

I'm running a K3s and have a popping noise through the external speaker when turning on the rig and to a lesser extent when turning it off.  I recently changed speakers, thinking maybe a change would help, but the issue is still there.  I'm currently using a TenTec 307B speaker.  I've checked the cabling and terminals and tried a few different shunt capacitors across the speaker termnals.  Does anyone else have a similar issue?  Any ideas what to try next?  Thanks.
