No. Distortion from amps being over driven is what damages most speakers, not good controlled power. (Your ears on the other hand....go easy!)
Overpowering my speakers
I have Gen One Klipsch Forte. I have Nelson Pass’ Nakamichi PA-5A 11 on the way. Fortes are efficient 99db, (100 WPC max)….and the Nakamichi is 150 WPC.
Should I be concerned?
My speakers are 9/10 condition, with a 12” passive radiator. All playing is conducted through Bluesound Node. Thanks
