I have the EV Sb120a, its predecessor, and it is 400 watts continuous - to me that's RMS. I use it in conjunction with two Mackie C300i passive 2-ways hooked to an 808s power mixer. That is one sweet setup. The 120a is full without being overbearing. There is a gain and output control on the back panel that will help even out the sound, if need be. And, it's lighter than the Mackies.
