How to set up REL Subwoofer?



How do you set up a REL subwoofer [R-205] as far as the connection? This is only for 5.1 HT, watching movies (BD/DVD) and HDTV broadcasts, not for music playback.

I haven't received mine yet and this is also my first 5.1 HT system/sub. Glancing over the online manual leaves me a bit confused. I thought subwoofers used a single phono cable, but REL supplies and emphasizes use of their Neutrik Speakon High-Level cable. Is this the connection most REL owners use with a HT set up? I also got the impression that you can, or should, use the phono cable w/ .1/LFE input in conjunction with it. The A/V receiver is a Marantz SR5004.

For music reproduction the high level is better, My HT is also 2 channel so I can't comment on 5.1.
For HT, you should connect an RCA (phono) cable for the .1. If you also want the sub to supplement your other speakers, then connect the REL Speakon cable to our amps speaker terminals as instructed. Both will work at the same time.

So the phono cable with .1/LFE input needs to be connected? The Neutrik Speakon cable is only a supplement? What does that mean, what does it do that the phono .1/LFE doesn't? What am I missing w/o it? Can you use the Speakon cable on it's own?
