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.

I have two REL T5 subs, one for each channel (HIFI stereo listening only)
what is the correct cable set up with the Neutrik cable/s. 
I am guessing its (+)sub to (+)amp and (-)sub to (-)amp and the earth to the amp chassis? for each channel? Do you think this is correct? 
Thanks in advance

Hello,

 I have B&W 600 series 5 speakers. Planning to get a REL T9i sub now.
Got a query regarding the connection. My avr is a denon avrx2300. I want to connect the REL through High Level input as well as LFE. For movies i want to use the LFE primary so my speakers will be all set to Small with a crossover to 80hz. For music i want to choose the High Level Input & use the denon avr Pure Direct mode which will basically make my Front speakers Full Range. Is this way possible with the REL sub?

Thanks.
