Pricing probably depends a lot on which side of the border you are on.
Yup. The only reasonable ID options in Canada are SVS (if you are close to TO and shipping isn't too much) and Axiom.
I'm quite happy with the EP350. It does not reach quite as low as some of the other ID subs close to its price, but what it does, it does extremely well: clean throughout its range and lots of headroom in the upper bass to give you good punch.
FWIW, in my room I get a flat response down to around 21Hz.
The 400 has considerably more oompf than the ep350 and looks to reach a little lower.
