would be nice if surround receivers were more flexible with where you can send the LFE channel
i can sense it, someone out there is thinking right now "but what about the (LFE + main) option"
most people think that sends the LFE channel to both the subwoofer output and to your main speakers but it doesn't
when you set all your speakers to large and subwoofer to "yes", the only channel going out to the subwoofer output is the LFE .1 channel
with "LFE + main" option selected, the subwoofer output on the surround receiver will now send the LFE .1 AND the bass from your "main" channels as well
here's an example:
let's say you have 7 bp7000sc's all the way around and each channel set to "large" and dual trinity's for the LFE channel with subwoofer set to "yes"
let's say the director sends a 20hz thump to the front right channel
the trinitys will be sitting there doing nothing and your front right bp7000sc will handle the 20hz thump
with the "LFE + mains" option turned on, the 20hz thump that was sent to the front right channel will now be reproduced by the front right bp7000sc AND the dual trinitys

otk, Thank you for the good explanation. I thought this is how it all worked.
Let's say for example that you set your powered towers to "small" and set the crossover to 60hz? Do you lose 20hz thump all together if the subwoofer setting is set to "lfe"? How about "lfe + mains"?
Totally different scenario... no subwoofer in the mix...
Ok, now say that you have powered towers up front (set to "large") and you have no subwoofer (which the case with me)? Where does the lfe signal go? Where does the bass go that is below the crossover of the rears if they are set to "small"? You might answer this for the scenario above as well (subwoofer in the mix).
