Initially I was disappointed at the product since I was testing it with regular radio signal. I did not have the proper cables to try it with my Ipod or cd player. Fortunatelly after trying it with my Ipod and dvd player I found this product to be great. Crisp clean sound, easy installation. They are sold individually so I purchased 3 of them for an outdoor area. Accompanied with the right received it can produce great sounding music. The bass did crackle on some mp3 songs of bad quality when I raised the volume. But for the size of this speaker I was surprised at how high I could raise the volume before this happened. I recommend this product!
