Newegg halves their price of this Polk Audio RM705 5.1CH Home Audio Speaker System from $499.99 to $249.99 with free shipping. This beats the next-best price we could find by $31. This surround sound system has lightweight speakers, so they can easily be mounted almost anywhere. It includes four speakers, a center channel speaker, and a 50-Watt subwoofer. There is no sales tax (except CA, NJ, and TN).
