I was lucky enough to have both of these at the same time, and could A/B test them. The $730 SL 112 vs. the $300 Rumble 112. I made sure to keep settings the same between cabs. I also tested each cab in the same spot in the room by moving them back and forth. I tested with a fretless Precision bass and an Engelhart upright with K&K pickups. My goal was to return one, and buy a second of the other. Very interesting results. The first 45 seconds really makes the difference clear: I returned the SL 112. (!!) EDIT: Guitar Center has re-listed it for the same discounted price I paid – used, mint condition. And it was not about price. Price only entered the picture after realizing that they're both such good cabs, how tough to decide, it made sense to go with the one that's less than half the cost of the other. I have to admit, my friends and I like the tone of the Rumble better: The Rumble gave me my bass's full tone. Whereas the Aguilar sounded scooped in comparison. Secondly, the Aguilar sounded more gritty, but not in a good way. The Fender sounded more musical. This is probably the "tone coloring" that other reviewers allude to. My theory: the perceived better sound is due to the crossover and tweeter in the Rumble. I have no idea what they are though, versus the Aguilar.
