Very big +1
When it come to sub/s as you said, location is everything.
Also agree, when someone coming from a lesser sub, to a quality one. That person may feel the new sub weaker, since it does not emphasize some frequencies. Since the perception of distortion from a lesser sub, make it sound louder.

Honestly there are certain cases where I can tell better performance than my old sub, but my old sub may have been louder.
My old sub was a Klipsch
12-inch down-firing woofer
650 watts of dynamic power (300 watts RMS)
I followed this to a T
Does anyone have any suggestions for me to try? Right now I have the sub at max-volume. With my Denon 4400H, I am having to turn it up to 60 + just to get any so-so bass levels.
As mention in the above quotes from imureh
. When it come to subwoofer, location is primordial.
My suggestion would take some time to read this Guide;
Guide to Subwoofer Calibration and Bass Preferences
While it is a long read. Everything you need to know about subwoofer settings, how it interact in a room and also your AVR settings are in there. And also have quick links for different sections.
I had to read this Guide a few time, but it was worth-it. my bass is now perfect for my situation
Your older Klipsch 12-inch down-firing woofer, is not even near the league/performance of your new PB-4000.
What previously found to sound louder, could very well be contributed to some frequencies been boost, or having some distortion that is perceive often as been louder.
And last, but not least. Many find after a calibration, that there is not enough bass for their taste.
It is not uncommon for many members, adding +5-6dB to the AVR/AVP bass setting, after calibration. Mine is +2dB.
