I'd like to eventually get a 112 cab but use several low-wattage heads through it. I've found I like closed-back cabs more than open. What I'll probably do is get an Avatar or Whitebox 112 close-back cab. My thing is I want a really versatile speaker. It doesn't have to do any one thing great, though what I play most is blues, classic rock, and lots of fusion and prog rock. None of the heads I'd use would be over 30 watts. Hopefully this is enough information. So, what would be a really versatile speaker to use?
