I have EP500 (love it) and I also have EP175 (not so great). But with the price difference, I can't really expect the 175 to perform anywhere near the 500. So when I say my 175 doesn't perform to par, I always put it the context of "as compared to my EP500)"
I'll be the first to admit that's like comparing a college quarterback to Aaron Rodgers. It's neither fair nor useful.
I love watching movies with my EP500. With the EP175, not so much. You get used to what you get used to. It's like this: if you get used to flying business class, it's hard to go back to coach. If you get used to driving a luxury automobile, it's hard to go back to a lesser model. Once you get used to a great sub, it's hard to go back.
