RM6880 Surround connections

I just purchased a RM6880 5.1 system. I've been looking at the speaker connection print for the subwoofer and I have some questions. It shows no connecton at the "line in" (RCA style) plugs, but has speaker level inpus and front speaker outputs. The remaining speakers are powered directly from the receiver. Can I run all of the satallite speakers off my receiver and use the "line in" connector for sound input to the subwoofer? What is the reason for powering the front speakers off of the subwoofer?

Next the "line in" connector says filtered. I have to guess that the subwoofer has an internal crossover that filters the high frequencys through this connection. Is this correct?

I would just like to have an idea of how I should hook this system up before I put everything in place. FYI, I have connections at the reciever for a center channel, subwoofer, and the remaining 4 speaker. Thanks for the help.

    Either way should work fine and yes the Rm 6880 Sub has in internal cross over.I have already asked this question and its been discussed in this thread below.But yes you can do the polk way or the speaker input way.

    You can only do the fronts with speaker level inputs by changing the speaker settings to LARGE or full range.So that the low frequencies will be sent to the subwoofer and your speakers will be getting the mid range and the highs.

    OR

    You can do the RCA level input in the sun to connect to the receiver. Actually I am using a Y split sub woofer cable to connect the sub to tmy receiver.Again it depends on your taste for the sound..

    Enjoy your new system!!

    If you do hook it up this way (line in on the sub and LFE or SUB out on the Reciever) make sure you turn the crossover on the sub all the way up to max. (200hz or more).

    You don't want to double filter your bass and both the line in and LFE out are filtered.

    You are right about the cross over thing..but..

    The sub in this package doesn't have a crossover knob.It is set internally so everything is been taken care off :)

    You can try both running Pre out from receiver to sub and as the Polk suggested hook up, i.e., Front speaker output from receiver to sub and run the front speaker from sub, and on the receiver input in the info as "no sub"
    try both with same CD, DVD, Movie etc with same volume same, effects and choose the best you hear.:)
