I'm a mobile DJ and I have 2 pieces of ES802 columns and they are truelly amazing!
The sound they produce can compare to the sound produced by 2 or 3 times more expensive speakers (I am speaking about the quality and not the loudness). I prefer to lower the highs as well as mids a little bit for the better sound quality as the highs are really strong on these tops. Bass - amazing for 12'' speakers. Also, they go quite low. In addition to this, I have heard worse sounding 15'' subs which are more expensive than these little mighty subs.
The only problem with the subs is that then you push them quite hard, the material under the protective grill starts to emit a bit annoying sound. It is because it's not a foam but a plastic-like material with thin plastic seams that rub against each other when a lot of air is being pushed. Although, it's fixable.
I have been using them for one year and they have never disappointed me. To be honest, I have never reached the limits of those speakers and they never get hot which is really surprising. Maybe that's because in my country we don't have as big venues and a 50 people venue is already considered medium-sized. I think they are good for maximum 70-100 people and just perfect for under 50 people.
Speaking about compactness, I manage to put it all together in my 2012 Audi A4 Avant which include these speakers, cables, lightning with stands as well as DJ table and so on. 🤣
Overall, I give them strong 5 stars and if you are considering buying these columns - just do it, you WILL NOT regret it!
