SWT–X Wireless Subwoofer Kit

Although correct placement plays a key role in optimizing subwoofer performance, sometimes it imposes the inconvenience of running long lengths of cable through walls, along baseboards or under floors and carpets. To solve the problem, Dynamo 600X, 800X, 1100X, and 1600X include a connection port for an optional wireless system. MartinLogan’s new SWT–X Wireless Subwoofer System incorporates the latest in wireless audio transmission technology. Easy to install in the subwoofer, the SWT–X receiver requires no external power source or audio connections.
