I have a Denon 1909 receiver with Infinity TSS-1200 speakers & sub. The sub, I unfortunately learned, didn't have much in the way of quality or longevity, and I have since picked up this sub
Previously (with the Infinity sub), there was smooth, seamless crossover between the speakers and the sub. Now, although the sub sounds great, it sounds like there is a gap or "no man's land" where I should hear bass but don't. Think of a college football game with the band playing: no bass, no bass, band volume increases, and only after that, finally, bass from the sub kicks in. It's not smooth at all.
I've read a handful of articles the last few evenings, but I'm still uncertain. I can set individual crossover frequencies for my center channel, front channels and surround channels (in addition to that of my sub, of course), but I haven't seen any articles address this (or they were, but I was unable to understand it?).
I currently have my sub's LFE rolled down to 80Hz. The Subwoofer Mode on the Denon is set to LFE (as opposed to LFE+Main). Crossover frequencies on the Denon are currently set as follows: front (small) 200Hz; center (small) 150Hz; surround (small) 200Hz; and, LFE 80Hz. All of these are the settings that were originally on the Denon when using the Infinity sub after a successful Audyssey set-up.
My apologies for my long-winded post (and for my noob question), but any help would be greatly appreciated, even if just pointed toward a helpful article that perhaps I've overlooked thus far.
