The Gemini AS-15TOGO is designed for powerful stereo sound with a rechargeable battery in a convenient portable package. Thanks to its backpack size, integrated retractable handle, and smooth rolling wheels, this feature-packed speaker has you covered whilst on the go. It combines the deep punch of 15” woofer with 2” high-frequency compression driver to create big, bold sound, regardless of its application. You would be hard pressed to find all these features in one pack - Bluetooth, FM radio, USB and SD playback. Best of all, you can customize sound with the professional audio mixer integrated right on the back panel.
