What if as in my case the DIY sub I am constructing does not use a plate amp & therefore does not have a XO.


Cam, I meant you could set XO for your subwoofer at your AVR7200, e.g. 40, 50,80,....100 Hz etc. If you set it to say 80 Hz, your receiver will send (via the subout) anything from 80 Hz down to your sub. If your sub has a plate amp with XO adjustment, you should disable it, or hook up your AVR7200 subout to the unfiltered input at your sub if your plate amp has such input. This is to avoid double filtering. If your DIY sub does not use a plate amp then you may have nothing to worry about. Again, as you know, the XO for the "sub" is set at the AVR.

As for the LFE, I could be wrong, but I thought it refers to the LFE channel, that is, the .1 part of the 5.1 or 6.1 channel. As such, the frequencies in that .1 (or LFE) channel depends on the DVD movie itself, not your AVR. From what I read in the past, the upper end of the material in the LFE channel of typical DVD movies does not go higher than 120 Hz.

If I misunderstood what you are asking, please ignore this response, otherwise I hope I managed to clarify my point.
