According to this db chart, your target listening level is fairly low. Full-bodied requires pressurizing the room to some degree. Difficult to achieve with small drivers and a small cabinet - at a low volume. Of course, you can still get excellent SQ.
Years ago, at T.H.E. Show, I heard the JBL K2 S9900 in a very small hotel room - maybe 10’ x 15’ - well damped. At around 60 db, the SQ was phenomenal. Definitely full-bodied. It was one of my favorite rooms.
This owner loves his JBL 4367's.
