Anyone know how to set up Rythmik subwoofers on an ARCAM AVE550 receiver?

I have been looking at the F12 G (the G has the paper cone material).  The lighter weight material supposedly makes the texture of the bass more lifelike and dynamic for music with a very fast response and decay.  
Regardless these seem to be special subwoofers compared to the rest of the pack.  
As for connecting to your receiver definitely connect to the speaker terminals of the amp (parallel with your main speakers).  Connecting to your amplifier will allow the best possible integration with the main speakers because they are each receiving the same signal and sound signature.  
If you make sure that the subwoofers are positioned reasonably - along the main wall, about 6" or so from the wall and not in the corners of the room I don't believe room correction is necessary.  I have measured the respinse of many subwoofers and positioning them reasonably flattens the response which avoids peaks that require correction.  
If this sounds like a good starting point we can walk you through how to adjust the crossover, phase, level, etc. for best possible integration.  

LFE out? did you mean preamp out? LFE out is exclusively for home theater if I am not mistaken (low frequency effects). If you don't use the high level inputs via the speaker cable, then I would either use the extra set of preamp outs on the preamp/receiver, or if only one set, just buy a splitter and run an extra interconnect over to the Rythmiks left or right channel RCA input.

Then on the rythmik you can best set what frequency sounds best to blend with your mains (don't have to touch the mains)

I talked to an ARCAM dealer and he said there is a setting on the ARCAM.  If I select stereo direct, it will not play the subs.  If I just select stereo it will.

Jim Salk and Brian Ding told me the way to hook things up is by using the LFE connections and let the ARCAM manage everything.  One person told me my ARCAM does not have a bass management system.  If so, I bought a piece of junk.  Maybe, I can control some of this by using some adjustments on the Rythmik subs.  I most likely will set the gain at halfway.

Maybe Rythmik would be wise to sell their subs through dealers so customers can at least hear them before you purchase them and the dealer could set everything up.  Problem is there are few ARCAM dealers.  

Right now I think I better go back to school and get a degree in electrical engineering like so many people who belong to Audiogon do.

Sorry bdpd,  I didn't mean to upset you.

I talked to a really good speaker manufacturer and he told me to set things up with an SPL meter.  This is pretty complicated for someone who does not have a degree in electrical engineering or for someone who is not a dealer.

I really think the Rythmik direct servo technology is the way to go.  Just wish they had a speak on connection and design as what REL has.  I do thing the Rythmik F12 Signature will play down a lot lower than REL.  If I can find someone who could set things up it would be a lot easier.

The problem is ARCAM has horrible customer support.  They do not provide phone support and I think this is a horrible way to support their customers.  They also do not respond to emails.  I wish I had purchase the Anthem 5 channel amp and their HT processor.  Life would have been much easier.  The Paradigm district sales manager is fantastic and he has been so helpful.
