Do you have them wired as mono? In series? That would mean it equals to 16ohm on your amp!
That would explain why they sound so muted
I was talking about the Mono signal from the PCB. I am unsure if the Sega PSU amplifies the signal from the PCB in any way? Or perhaps the volume control is just directly controlling the volume output from the PCB?
Would be good to hear feedback from @jepjepjep about how he found the LG speakers on his NAC.
