A massive sound from a compact and versatile unit. A huge 300 watt amplifier provides plenty of power to move the 15 inch woofer and large horn speaker. It includes two wireless microphones for MC / Karaoke. To keep the music pumping, connect your favourite music streaming source via Bluetooth®, or via a SD / USB. Playback controls and information are provided on the speaker. A line and external speaker output is provided for expansion also. Bass and treble controls accompany the master volume for fine tuning of your sound too. Everything is enclosed into a single heavy duty enclosure, with roller wheels on the back-side to assist with transport.
