As long as its done well, why not? I had Maggies for years and they were at their best when a decent sub was integrated well. Same true whenever I visit my local Maggie dealer. His systems always sounds good and he is not afraid to use a sub with Maggies when needed.
What it takes to do it well can vary. Room and acoustics play a big part.
