At more reasonable prices, I give them four. Please reference many of the comments found for the linaeum speakers and the optimus speakers. But I've found that in the Paradigm Studio 20's as well. The speaker does best with acoustic music, jazz, and the like. There they can recreate the sound of a live performance with a very pleasant, full quality.
Price is a major concern.
Dealers ask between 895 to 700 a pair. You can order for Aura directly if you do not have a dealer in the area. So you can imagine what dealer cost is for these speakers. OEM'd for radioshack by aura. Check it out.
