This is an all-in-one multimedia speaker that brings your Bluetooth and non-Bluetooth devices into harmony. You can pair all kinds of Bluetooth devices wirelessly such as your computers, smartphones, tablets, or you can also wire connect the speakers to those devices if they have a 3.5mm audio input. The system includes two 84x153x103mm / 3.3-inch x 6-inch x 4-inch satellite speakers and one 161x200x280mm / 6.3-inch x 7.87-inch x 11-inch 5" subwoofer with 68 watts peak power output to create a wide and full sound audio experience. The stable and thick wooden enclosure subwoofer can effectively reduce the undesirable resonance, and obtain a more pure and rich sound. Speakers sound best when they are level with your ears when you are listening to them, that's why these two satellite speakers are stand-mounted designed to bring them to your ear level for optimum sound performance. Equipped with a 131mm large-caliber bass unit combined with a front inverting tube, so the low frequency is strong and powerful, and the panoramic sound field atmosphere is constructed. Buttons that include volume up & down, input selection, bass adjustment are all located at the side panel of the speakers for easy control and adjustment.
