Atlantic Technology presents a wireless alternative to RCA audio cable-- the WA-60 Wireless Audio System replaces long audio cables with low-frequency response down to 10Hz.
Designed for subwoofers, the system can also find use in connecting receivers, computers or any line-level audio devices across a room or from one end of the house to the other, with 21m range (or 45m line-of-sight). As a successor to the WA-50, the WA-60 improves low frequency response while boosting range and increasing the number of channels.
