You can't have too many bass traps...

Well, that's why in my original post I said one needs to define what a bass trap is. Generally speaking, people buy "Bass traps" to tame all that low bass output. Whether they are right or wrong, that's what people do.....

Bass traps will absorb bass frequencies.  The idea is to absorb this energy so that it does not get reflected back into the room.  The biggest problem are when reflected bass hits the generated bass from the speakers and cancels itself out, creating a bass NULL.  This can be heard as a significant drop in bass around certain frequencies.  Bass traps will reduce this reflected energy and reduce the bass NULLS, therefore allowing more bass to be heard.

I'm going to disagree.  I've measured 20 dB peaks as well in a modest living room.  That peak prevented the subwoofer level from coming up. Nulls, if narrow enough, may not even be heard, peaks though are ugly to listen to.

Not disagreeing with you.  peaks can also be a problem.

Mike Lavigne, 

Just looking at pictures of your amazing room. Where are the bass traps in the back hiding? Is there scrim on the back walls?
