Please help me not make a dumb mistake

I am putting together a new secondary system. Among other things, I am planning on hooking up a Rhythmik F12G subwoofer using the subwoofer's SPEAKER level inputs. On the Rhythmik website, its says:

"Our speaker level inputs are only compatible with power amplifiers having single ended outputs with black lead output labelled as "COM", "GND", or "Ground". Wyre4sound power amplifiers and others with differential outputs are not compatible."


The amplifier I would like to hookup to the subwoofer is a Prima Luna Dialogue 4. The Prima Luna's black lead outputs are not labelled "COM," "GND," or "Ground." They are labelled 0 Ohm. Is that the same thing as ground?

In other words, can I safely hook up the F12G subwoofer to the Dialogue 4 amp using the subwoofer's SPEAKER level inputs?

Thank you.

Thank you, Yogiboy. I appreciate the help.

Fiesta75-- I don't have the option of using the low level subwoofer input in this system as it is currently configured, which is:

Mac mini --> Benchmark Dac3 (dac/preamp) --> Prima Luna Dialogue 4 --> Dali S180.

I have used the low level inputs on other subwoofers in different systems with good results. This will be my first experience using a subwoofer's high level input. Hopefully it works out.

Ozzy62-- As you said, I have heard many people report that speaker level inputs can result in a more seamless integration. I hope that turns out to be true in this system. In the past, I have spent many hours trying to get subs to integrate using the low level inputs. I have sometimes achieved good results with the help of digital EQ and experiments in room placements. In this system, I will have no EQ capability and only a little latitude with room placement.

Cleeds-- Thank you for the good advice. I have reached out to the manufacturer and am waiting to hear back. I'm feeling more confident that it won't be a problem given russ69's experience. 

Russ69-- Thanks for your comment. It sounds like it will work fine.

I appreciate the help folks.
