I'm trying to decide between two used bass rigs, both with the Hartke 3500 as the amp. Would it be better to get the rig with a 4.5 cabinet (4x10 with a 5" tweeter) or the one with a 115XL and a 210XL? I play rock music, and they're both around the same price, though the rig with the 4.5 cab is 3 years newer. I'm leaning towards the rig with the 115 and 210, but can't decide. Which one would be louder, and which would help me get a fuller sound? Thanks!
