(IDEAL FOR '2 SITE' EVENTS) This Add-on is for event's and party's that start in one location and move to a new one. These smaller lighter speakers are ideal for Outdoor Ceremonies in intimate garden or gazebo gatherings-- Great when a smooth location transition with zero pauses, other then the swift trip to the 2nd location, is absolutely necessary. You won't be disappointed when your guests move from the lighter tones of your ceremony to your party's main hall with your best music already playing, setting a welcoming tone as they arrive!
