If I were looking for a cab, I would take a serious look at Audio Kinesis cabs. Duke is one of the kindest guys I know. I haven’t heard his bass cabs yet, but I’ve heard a lot of his high end stereo speakers over the years which are some of the best out there. His bass cabs offer the ability to change box tuning which is important as a box tuned for a 4 string may sound thin on a 5 string, or a room resonance over boosts the bass and box tuning can be changed to suit the room better.
