The EP500 goes lower than the Paradigm's. The EP500 also has more power. Those differences may not be worth the delta in price to everyone, but I mention it because you need to compare apples to apples when talking about price.
The EP600 and PC13 are comparable, the EP800 is an upgrade over either one.
The 500 plays to 18 and the DSP 3200 plays to 22 going by the specs, I would be willing to bet many would take the DSP price over the EP500 and give up the few hz difference or you go for the 3400 which hit 19 and still costs less. This is why many say Axiom is over priced. SO far as power goes, like you said earlier it depends on the design, wattage specs doesn't mean alot.
