Vandersteen 2W sub connection


Recently purchased a pair of vandersteen 2C speakers and a bi-wire cables for them. Now looking to add a vandersteen 2W subwoofer but completely baffled by connection requirements. Shared the link to a pic below and, if anyone is familiar and can help, I’d really appreciate it. They have 4 banana plugs and 1 banana/spade plug yet the manual mentions an RCA connection. Wtf!?

It does come with a WX2 crossover. Doesn't say "2Wq" on the back, just "2w". Does the red plug look like an RCA? Looks like another banana plug to me.

Hey guys, sorry got busy with work. I may have missed it but how exactly do I connect that sub? I have a 2 channel power amp with a 2 channel preamp. Speakers are bi-wired. What other cables do I need and how do I connect them. The diagram on the speakers doesn't really clarify. Really interested in that sub but confused about connection.
