While I was at their site I came across an article on the Axiom EP500 and EP600 subs. The EP600 has to be the tallest sub I've ever seen. I'd love to see one of those in action.
Decent review, not much in the way of objective performance but there's a kind of compression graph. As expected, he found it really "musicalish". The graphs do show nicely what the room comp and eq functions do. And check out the reviewer's actual FR plot vs. the one on the SVS site. Pretty damn close, especially compared to the fantasy graphs, hype, and fabrications we've seen from other sites.
Pretty typical of their reviews. They do give me enough of what I want to know to get a pretty decent idea of what most of the reviewed products are capable of and what to expect.
