I haven't heard that sub but I do own several sets of Paradigm speakers and they sound very, very good. Their performance is way beyond their retail price, so if you can spring for the bucks, I'd just buy a 25 and determine for yourself. Odds are, you will be happy with it.
And, of course, there is nothing wrong with a 15 backed up with a 25....
