With this wireless speaker cable, you can wirelessly connect the (rear) speakers of a surround set. No more loose audio cables in your room! The Speaker Anywhere 650 guarantees digital transmission, which ensures high-resolution sound. The set can be expanded with up to 2 additional receivers (available separately), so you can send sound to speakers in another room if desired. It is also possible to use an additional receiver to wirelessly connect both speakers to the AV receiver/amplifier, without requiring a cable between the two speakers. Use multiple sets in one room to also make your front speakers wireless!
