Why so obsessed with bass?

There are no issues with bass if you know how to properly integrate subs with your main speakers (bookshelves or full range). REL subs allows easy integration for home theater and 2-ch audio from a single sub. Check them out!

Going by all the recent threads you’ve started, may be you’re over thinking audio. It’s really not that complicated to setup a decent hybrid system that’s is equally good at movies and 2-ch audio.

The only recordings to contain subsonic energy are a few digital made since ’85.
If that’s not your fetish just ignore.
Prior to that the only way to "record" low bass was with control tones:

Pretty much just a gimmick.
The only other time I ever felt it was with the IRS V’s in Music Room One playing "Thanks To You"
I’m sure they’re even stronger with new woofers.
If you stick with snalogue, bass to 30 Hz is usually plenty.
You certainly don't have to redesign a living space to accommodate more than 2 subs for "perfect" sound on very few demo recordings.

Coming up next week “whats the obsession with mids and highs?”.  
Bass is 1 of the 3 parts of music, no?  How many parts are you interested in?  2 of the 3?

Good bass response transforms a system.  Everything from classical to acoustic guitar sounds better.  Deeper, wider soundstage.  Mids that sound a bit cleaner.

I guess thats why I am obsessed with bass.  

Not as much an " Obsession " as an appreciation.
