WiSA stands for Wireless Speaker and Audio and launches this month at CES 2019. It means a growing variety of wireless speakers with high-resolution surround. WiSA is a beautiful and special home theater from Reference Wireless series. When we list the speakers, there are RW-34C center-channel speaker ($699), the RW-51M Monitors ($699), and RW-100SW ($499) wireless subwoofer. You can choose which ones put together, and all of them are internally powered, demanding only a power source to work with WiSA transmission devices.
