ELEMENTS Smart Base is a flexible, extendable PA with onboard amps that deliver a total of 2,400 watts. That?s plenty of power and headroom for larger clubs or smaller open-air gigs. Sporting two integrated Class-D amplifiers with 600 watts, the E 110 Sub AS subwoofer packs a big enough punch for a wide range of audio tasks. Able to handle 300 watts each, the E 835 mid/ high units come with those smooth E-Connect couplers that provide a cordless connection. This PA is easy to carry and fits into the trunk of a car. And if you want more bass and greater range, ELEMENTS Smart Base is easily extended with two handy Add-on sets.
