Excerpt: The Yamaha NS-AW392 is similar to the NS-AW592, but it is not as impressive. The design is more compact, but it seems some quality was cut down along with the design. This outdoor speaker set has a slightly better than average frequency response, but it has the lowest sensitivity rating in our review. Nonetheless, this is still one of the top ten best outdoor speakers available.
Pros: The Yamaha NS-AW392 can produce frequencies above the range of human hearing.
Cons: It has the lowest sensitivity we found in our review.
