Klipsch has no guts?? What do you mean? It would help us know if you could provide more detail. Based on what you've told of your priorities (lots of bass, high spls, and wall of sound for rock/blues) Klipsch should be ideal. Klipsch brightness can be tamed with the right amps. The vintage stuff were designed for small tube amps (also explains they're lack of deep bass which would expose any poor damping factors and require much more power).
Paradigm are good value for traditionally retailed stuff (better value than B&W), and stretch from entry level to quite high quality. Paradigm has no real vices, but no real "personality" either. Like B&W, they just sound like "hi-fi" (artificially reproduced sound, not live unamplified music). My vague impression of Cerwin Vega and Def Tech is lower quality versions of Klipsch. RBH looks like a member of the "brute force, more drivers the better" club.
Why not just buy PA speakers? Frankly it seems like you're hunting in the wrong place as what you've described is rather opposite of the design priorities for most high-end, audiophile speakers like Taylor or Emerald Physics, unless you're ready to take the edge off the gritty rock sound.
Another option from around these parts is Hawthorne Audio Silver Iris. High efficiency, well built, solid response down to 40 Hz, and a wall of sound from a $300 15 inch coaxial driver that you can mount in a 24 inch square piece of plywood. They also sell matching woofers for more bass. I've heard them with and without the extra woofers (that were mounted in the ceiling as infinite baffles) and the woofers only helped for extremely deep bass heavy material (could barely be called music).
