I guess I can say that if they even make sound at all, they are a great value. For some customers, that is really all they need. However, I find it hard to put my stamp of approval on these speakers. Guys like me are obviously a bit more discerning about sound quality. Some people are looking for a diamond in the rough, and this system is not it.
For home theater, this system will be an improvement over a TV's built in speaker. Again, that's all some customers will need. Maybe add a subwoofer and cross higher to remove some of the problem boom.
