I've been using it for few months already and it has stayed in my arsenal for smaller gigs (50ppl+) the power is okay for closed spaces , if you turn it on on open space, you loose a lot of bass after 5-10m , be aware of that, if you have 2 units, maybe you can have better sound, option is to buy s1 subb paired with S1 pro , that could be a good combination for larger events.
only con is that you have a small 6'' speaker so the bass won't come out so deep as you will want, I hooked up mixer to it many times, and you have to be carefull not to overclip or distort the input. Speaker doesn't like loud sources cuz it gets you feedback very fast, from my stand point that is okay just turn the speaker to audience, if you use it as a stage monitor , be careful with input gain
- sound is great , very clear, and the reverb function is usable but not for every situation, more for busking on street..
