Bass Management

I have Acoustic Research AR1's in front with powered subs.
I have full range non-powered speakers for surrounds, and therefore want all channels to be driven in full range.To do this, I must select "Large" speaker setting for my front powered towers in order to be able to select "large" for my surrounds. My Pioneer receiver will not allow for "small" fronts and "large" surrounds (if you select "small" fronts, all others including center, must be "small" also). In addition, AR strongly suggests that I use the Speaker connections for the mid/tweeter and the LFE
connection for the subs on my AR1's. When I use only the speaker connection, I still have PLENTY of bass volume on both music and movies, but I have recently plugged into SACD and DVD-Audio, which have the six channel output directly to the receiver's multi-channel input. One of these channels is specifically marked "subwoofer". My question is...what happens to this channel? Does the receiver mix the LFE info into all of my "full range" speakers, or is it only in the fronts, or is it possibly lost altogether? Please help me with any comments or suggestions!

Thank you!

Soogood51... correct me if im wrong but i think what
your saying is put the ICBM between the DVD-A
/SACD and the 6CH input on the Yamaha. Forever he is not saying to loop out and back in the reciever. The 6ch input is an analog bypass mode especially for DVD-A/SACD.
As far as I know (im 99.9999% sure) SOGOOD's theory will
work fine.

Voodoochile, yes that is correct, the other way to do it would be if you have pre outs for all channels. In thes case you would hook it in like you could a graphic eq.(between the pre outs and the amp in's. There are usually jumpers connecting them that you would remove. (do not lose them). In this hookup your player hooks into your 5.1 inputs on your receiver and the outlaw will do it's job just before amp. There is no loop back.

The ICBM does work as Sogood described and makes a huge difference on multi-channel SACD and DVDA. If the receiver has pre out/main in for all channels it will also work like Sogood stated. The ICBM has provision for stereo sub out as well. Sums all left side and 1/2 of center below individual crossovers and sends to left sub, same for right. Could be pretty neat for speakers will powered subs.
