Indeed, use a test CD/tracks to check if the wiring is correct.
Jamo E855 with their dual active woofers / speaker (is it bass reflex?) should have more emphasis on bass vs the Vandersteen 2Ce (one active / one passive).
I still use a pair of Vandy 2Ce in my study and the bass is more than adequate despite their dismal positioning -half hidden away between bookshelves - driven by just a 8W tube amp.
