Gemini AS-10TOGO is designed for powerful stereo sound with a rechargeable battery in a convenient portable package. Thanks to its integrated retractable handle, and smooth rolling wheels, this feature-packed speaker has you covered whilst on the go. It combines the deep punch of 10 " woofer with 1.2 " high-frequency compression driver to create big, bold sound, regardless of its application. Best of all, you can customize sound with the professional audio mixer integrated right on the back panel. Connect to the integrated Media Player via Bluetooth to stream music or use the USB port, SD slot or FM Radio. Includes a high performance wired microphone with independent volume control.
