People also say that my (former) magnepans, which are at least a bit harder to drive, generally, only sound good with lots of power. They were nuts. The speaker gets however loud the incoming...

connecting two power amp outputs to a single speaker is not significantly different from simply plugging one amp output into another amp output. The 4 or 8 ohms of the speaker will see very little...
