Paired with a Fire QLED TV. Unless you are a sound buff the 3.1 configuration is more than adequate. All speakers are contained within the unit so no treailing wires to satelite speakers. |Gives a good spacial sound. Using a HDMI ARC cable means that on/off and sound levels are controlled by the TV so you only need to use a single controller or no controllers at all if you use Alexa voice control.
