I'm seeing more and more 5 string basses in rock bands now. That low B goes down to 30.87 Hz.
The poll needs a "depends on what you're listening to" choice. For most things I prefer no sub. Even when turned down, I find that the sub makes most things too boomy. There are however, some songs where the sub is an absolute must have. For instance, on AKUS live Disc 1, Track 12 "Forget about it" When the electric upright kicks in, the EP 500 makes the room vibrate without being boomy; sort of a goose bump moment. The M80's just don't give that same feel. Yet on the same disc, Track 9, "Stay" with a standard upright bass, the EP500 makes it sound boomy.
Of course, this is in my room, YMWY.
As others have said, for movies a good sub is a must.
