Good workmanship, solid plastic enclosure, it also has feet with rubber bands (you can also put it on the ground and it won't go away). The output stage is digital for the low range and analog for the highs. A pleasant surprise is the display that you will find on EV speakers, which is completely similar to, if not the same as, all the gadgets that EV also offers. The sound reproduction is accurate throughout the range. For these dimensions, they offer decent sound. The only downside is that I noticed a minor resonance in the low range on a few songs, the origin of which I have not yet identified, what causes it. But otherwise I recommend it for all those who want a decently processed speaker for a reasonable price.
