You'll need a Z-Coupler or a resistor network at the BL-6000 end.
Here is some documentation.
2-pin DIN is always speaker level. It's easy enough to hide a Z-Coupler in an RCA plug. Measure the resistance of your "cable" from both ends first with the remote end open circuit, then shorted. If there is a Z-coupler in there, you'll be able to discover it.
I've forgotten the internal details of the BL-6000, but many of their speakers had printed circuit traces for built-in attenuaters. I would pop them open, remove a jumper and insert a pair of resistors.
This is very helpful. So you are saying the speakers had provision for attenuators? So if the existing Denon drove these normally, it is possible the attenuators are in place? Thank you.
