The ability to produce "deep and abundant" bass in a room is a combination of the speaker design/performance and the room design/performance. At one point some years back, I had Vandersteen 2CIs in an 18' x 35' room with a cathedral ceiling and the bass by far exceded that of my friend's Vandersteen 3A Sigs with 2WQ subs in a 20'x 20' room. Keep in mind that you need to explore more than just the speaker to achieve your goal.
