Do you not see any live music? A symphony? A local jazz club, Folk music? Really any live musical event, even a parade filled with marching bands. If you haven't, then all the discussion on what tight bass is is frankly a waste of time without the live reference point (s). The odds of exactly replicating it in a home is next to impossible but once you know what it sounds like, you'll know if you're getting there or not.
What is Tight Bass?
I’m confused. Speaker size with a large woofer…can it be tight?
is it about efficiency? Amp power? Electrostatic?
