I work as a mobile DJ. At various events with up to 50 people, I use two such subwoofers and two small Behringer B112D speakers :) The sound is enough for a small dance floor and it is quite good :) The red overload indicator is not very clear - when it is off, the bass is clearly not enough, and on the contrary, when the indicator shows overload, the bass turns out to be powerful and clean - you have to constantly play with overload :)
There are no more complaints :) Great design, compact size, good weight, convenient handles for repacking :) I put 5 stars :)
