On a Sunday morning after a gig I drove the gear truck over to storage.
For giggles I took a Titan 48 into the Guitar Center PA demo room looking for a trade - yes, I'm evil

I bridged their Crown XLS 402 to power it, and they had an A/B switch setup to compare subs. We set a steep bandpass filter to allow 35-150 Hz. Everything above that went through the SRX tops (idunno the model...)
The test song was Keb' Mo' "More than One Way Home"
The JBL SRX dual 18 subs couldn't touch it, nor could the Mackie or the QSC active 18 subs, nor could a pair of Cerwin Vega 18 folded horns on the much larger QSC 2KW power amp.
The manager made us stop because the fog machines in the adjacent DJ gear room were walking off the shelves, and a 24 channel Allen Heath mixer was ready to walk off the shelf.
They didn't get around to making an offer, but several customers asked me where they could get this BF brand equipment, so I told them.
The critical difference boils down to this. The Titan is loud and clean everywhere in the room, shaking the walls and making stuff walk off the shelves. Don't expect it to hit you in the groin like all of the other cabinets mentioned tried to do. None of those would get boxes walking off the store shelves. On a wall stacked three cabs high with every brand of speakers (JBL, TurboSound, ...) my Titan had the top cabs walking off their stacks!
