The QFX Elite Series WiFi & Bluetooth speakers offer the ultimate whole-home audio solution. Instead of wiring speakers to every room in your house along with a mess of wires and receiver in your closet, these speakers allow you to extend music to every room using your WiFi network. WiFi offers far better quality audio than you get from bluetooth, and allows you to listen to the same music in each room in perfect sync, OR different tracks throughout. (Ex. Living Room, Dining Room, Bedroom 1, Bedroom 2, Patio). They have bluetooth for added versatility and access.
