This seems to be the cycle I'm in right now. Ever since discovering Markbass last year, I've been going back and forth with this, and I just can't seem to make up my mind. I really have no need for anything other than the 12" combo. It sounds great, it's perfectly capable of filling a 1000 seat room with sound on its own (at least in the bands I'm in), and since I almost always run through the PA, I don't need it to fill up anything but the stage. And I love showing up with a bass, cable, and combo. I can get in and out of a gig as quick as a horn player. But doggone it, I really like having a wall of sound behind me. Bigger cabs sound bigger, and two or more drivers adds a complexity of tone that you just can't get with a single-driver cab. And it has to be at least as tall as an SVT cab. I spent the last 9 years with a single 410. The audience got great tone. I got nothing. When I had the SVT, all of us were happy. Except me at the end of the night when it was teardown time. I guess I should be happy that I'm able to have this choice. I spent a long time with only an SVT/810, and I got it back when they were cheap and nobody wanted them. So at least I have that going for me now. But common sense tells me that the big rig is wasted in a band where I can use a B-15 and have headroom , and even though it doesn't sound quite the same, the combo does the job and does it great. No complaints at all. But it's not a wall! I did my gigs this weekend with a wall, and even though it's a fairly light wall compared to an SVT cab, it added a good half hour to my setup and 20 minutes to teardown, but the tone.... So I want to hear from you players who used to use walls and scaled down...do you spend as much time thinking about something that matters to absolutely nobody on earth when you could actually be doing something?
