I've had and thoroughly enjoyed my NHT SuperZero's for over 15 years now. Still reasonably priced at $99 (whole system for around $850) People who visit us are also very impressed with their performance for their size.
My son set his system up with the NHT Super Zero and the Super One and a 12" Velodyne 2000 watt subwoofer.
It is awesome. He spend a lot for the speakers and the sub and is diving them with a Yamaha AV.
