Recently someone gave me, a Carvin BR210 cab, like I said with the old Rat Fur on it like mint condition. I have used other 210 cabs with my Markbass Jeff Berlin combo, and it sound it pretty good. But this cab does not. I cannot find much on it, so I guess what I am asking. Is it ported are what ever well, and is it worth reloading different speakers in. I don't really care much if it has a horn are tweeter. If you did reload it what speakers would you suggest. Are would you just put the cab on Craigslist.
