I've got a 104HF and I love it. Loud, present, and damn light. I've played in several of situations (and rooms) and it's performed great. I use it with a Little Mark II head and I've been thinking about running more power recently (those cones move a little too much with the LMKII). It's punchy as hell, though. Couple of caveats: I slap quite a bit and this tweeter is a bit "light on the sizzle" as BP magazine put it. I find that I need to really crank the tweeter attenuator (conveniently located on the side) to get that high-end pop that I need. Also, the cabinet is voiced on the low-mid side. Great for presence, particularly fingerstyle stuff, but might not be everyone's cup of tea. It's really a fantastic cab, though. Another bass player saw me ONE HANDING it the other day. I'm enjoying it.
p.s. BONUS--I just found out how to get that gaudy logo off of the grille. Cabinet looks almost "normal" now!
