Amazing for such compact design

RandolfCZ, 10.11.2017
Positive: I was very pleasantly surprised about the sound quality and loudness. It is absolutely sufficient for a small outdoor venue of ~100 people. Sure, the bass is what you would expect from 12'' woofer, so it wouldn't do for a rock band live venue, but for a reproducted music, this is a perfect small system that fits in a small car trunk along with the speaker stands, cables, mix, and there's still a place for a keg of beer. The audio quality is good even for home use (I didn't expect it from a PA system) - I am really not any close to being an audiophile, but I believe can tell a good sound from bad one.

Negative: On the other side, the control using a single knob is just silly. The system has many functions, and having to switch between different menus just to adjust channel volume vs. overall volume, that's bad. I would not recommend using it without an external mixer for any purpose than playing a single (mono or stereo) channel.

Neutral: The satellites are relatively directional, place it in a corner if you can, or farther from people when outside.

ES503 Versatility !!

thomas593, 04.07.2018
Perfect column with are satellites splittable for stereo rendering 2.1 or in pairing with a second ES503.
-Or then a twinning with his cousin the ES802 (see opinion ES802) whose dimensions and design are identical; for this it will pass through a mixer to assign each left or right channel, solution opted for our group to sound all instruments and singing pickups.
Slightly less powerful than the ES802 but it does not feel on coffee / concert use, terraces, pubs ..
The advantage of the ES503 is to allow stereo use 2.1 for small concert or have it replicate the voice and possibly bass drum, bluetooth is a bonus in our use but can send a playlist from a smartphone the time of laying beer is to avoid the silence that could scare the listeners.
Conclusion: super fast / simple assembly / adjustment
a sound quality system that will delight musicians, DJ's and even the particular thanks to the bluetooth function.
