I absolutely agree with you, Gonk. My lfm immediately "fit in" and kind of faded to the (terrific) background. As Joni Mitchell said: "Don't it always seem to go that you don't know what you've got 'til it's gone." We "have it" so the satisfying low end is just there.
My system is wired so I can turn off the five speakers and leave the sub on. It's interesting hearing the <40 cps information that the sub allows me to hear.
