DC offset level to avoid speakers damage-


Dear All would you help me to understand this?
My actual power amp has very low DC offset.

I understood that Pass aleph renomated amps that i am targeting have a quite high offset in the range of 50mV.
Something to be worried about ?

Which is the max tolerated level from a speaker ? Which kind of damage can occour ?
Any speaker is more sensitive ?
Tks

Not to worry - a 50mV output offset calculates to 3 microwatts dissipation in an 8 ohm load or 6 microwatts into 4 ohms.

Per Ohm's Law, power is voltage squared DIVIDED by the impedance
