«  pleasantly surprised »

First delivery made with 4 speakers alto ts 115a and I must say its working very well. I was skeptical about the sound of the plastic case and after test these speakers are really nice its treble bass are not very aggressive and has enough power round is also no need to make it are clipped ventilated thanks to the integrated fan speed to variable. In a room with sound jai 500m square 200 people without problems
