Not to imply that drivers within a speaker need be in parallel.
Impedance Matching Confusion
My stereo amplifier has two sets of binding posts for each channel. The user manual says that it can drive a pair of 4 ohm speakers if only one set of the binding posts are being used. If I were to use both sets of binding posts, it can drive speakers that are between 8 ohm to 16 ohm. My speakers are rated at 4 ohm and they support bi-wiring. My question is that if I use both sets of the binding posts on my amplifier to bi-wire a pair of 4 ohm speakers, will it cause any issue/damage? Thanks.
My amplifier’s Power Output: 200 W + 200 W (8 Ω) 400 W + 400 W (4 Ω) / The speakers are rated at 4 ohm with 90db sensitivity.

On this amp, there is nothing mysterious happening - those posts are simply wired in parallel. Hence the warning not to wire 2 4-ohm speakers to both posts, as you’d end up with a 2-ohm load.

Funny Sony, Most likely you have the EU/USA/Canada model, where the Japanese one is stating 2-16ohms. Both versions are the same, same mosfets, same transformer, same power supply, same rectifiers, minus a couple of electrolytic caps on main L&R boards (signal). Please note that both versions drive easily SS-M9ED speakers, rated min 2ohms and 86db efficiency. Late answer but i have seen it late.
