Small and convenient, but big in what it offers. Noise-free activation; sensitive and quiet potentiometers. Maybe the LED lights are too strong, but that’s a personal opinion. Compared to the more GK heads I have, it’s more than a step ahead of them - worth its price! Combined with their two GR112H-8 speakers, it offers fantastically calibrated sound, both indoors and outdoors. The only problem I had with this kit was the loose rubber feet of the boxes, which was fixed under warranty in a short time. It was only during this time that I really noticed how well the kit works, as I tried the head on several different boxes, from 4x10 ", 1x12" to 1x15 ". I can also say that the GK heads sounded better on their speakers. In short, I recommend !!
