The TeleStone is a wireless receiver enclosed in a durable, natural-appearing rock shell. It has two direct-burial speaker-level cables for driving nearby Rockustics speakers with up to 65 watts per channel (4 ohms). The TeleStone is accompanied by our sister company SoundTube’s WLL-TX-II transmitter, which is placed near your AV system. The TeleStone wireless system uses uncompressed audio for superior quality. (For best performance, the transmitter and receiver should be installed in a line-of-sight configuration.)
