I haven't audition Fluance but from my research, they are what they advertise. No gimmicks like "White Van Speakers" like Di Vinci or Theater Logic; claiming their speakers are worth $3,000.
For people with limited budget, it is a good entry level for those who wants a 5.0 system for under $300. Their build is nice and sturdy. Their weakness seems to be their center speaker. But overall, most owners can't complain for the price they bought it for.
