Been waiting for a price drop on these since I got the Klipsch Cinema 600, also on sale, on a pricematch at HN earlier this year.
Usually around this price point in the US, but in USD!
Designed to connect wirelessly to the Klipsch Cinema series - for more details see here
Other Cinema systems also on sale, but in this case buying the Cinema and Surround 3s separately is a better deal than the packages which aren't on sale.
Delivery extra, or free C&C.
