Used for about two months before we moved to a home with wired speakers. This system is in perfect working order and comes with everything, including the manual and original box. The JBL On Air WEM-1 Wireless Expansion Module surrounds you with great sound without surrounding you with wires and more holes in your walls, floors or ceilings. Set your speakers free with the JBL® WEM-1 Wireless Expansion Module. You’ll have audio throughout your home or office from your PC, A/V receiver, iPod or other portable music devices. The WEM-1 has a 50-watt-per-channel amplifier and receives crystal clear signals within a 70-foot range. It's built around a 2.4GHz proprietary system and ensures optimal performance. An EQ switch works with compatible JBL speakers. If you want professional JBL sound in an easy-setup wireless system, this is it.
