Working on a budget as usual, what would you get if you needed a bass cab, on a budget of $500-650, will gig with it. Currently using a GK RB 400 head. I was considering building a Carvin cab but after reading about Carvins they are good for PA's but not to great for bass cabs according to most of the TalkBassers out there, and I found the same to be true with the low end issue as well. I currently play both active and passive basses. I know it's an open question, not sure which manufacturers or speaker set up to consider as of yet so just looking for some great advise as always from the TalkBassers out there.
