RE: Amp cutting out on more efficient speaker. Why?
Posted by pictureguy on May 13, 2022 at 19:08:55:
Infineon BOUGHT International Rectifier and may be selling (changed in some fashion?) IR amps under a new name.
I have one of the original IR amps for test.....the 'reference' board version in stereo.
It is Just Possible that the amp doesn't like the REACTANCE of the speaker.....as opposed to a sheer bad 'impedance' match....
I suppose it IS possible for a higher sensitivity speaker (manuf #?) to actually be a worse load to the partnering amp. some wacky low impedance point coupled with 60 degrees reactance?
