Sorry I wasn't very clear. You said it best. A 20 to 25 Hz tone played by my 600 alone varies with the dimension setting.
What I meant by no bass from any of the speakers is that when a 20 to 25 Hz tone is played in stereo mode, it comes out from my 600 only. All other speakers don't respond. So I can't figure out why the dimension setting is varying the bass.
I googled this last night to better understand how the algorithm for PLIIx may be messing with the LFE but I had no luck.
I am very perplexed about this and I'm wondering if Denon messed up on the PLIIx implementation. I'd like to hear from others if they are experiencing the same thing please.
