I've often had questions about what speakers I can plug where into what amplifiers. If somebody can give us a basic understanding of this, it would be very helpful.
I suppose Richard is saying that if two 16-ohm speakers are wired in parallel, that halves the resistance and makes it 8 ohms. And I suppose they would make 32 ohms if wired in a series.
Or not. I'm mostly just guessing.
