### ⭐⭐⭐⭐⭐ Great sound
*by F***O on 27 April 2026*

Sounds great, the speaker is a little heavy so a two person lift is recommended. It’s very powerful so I wouldn’t recommend using it for small indoor venue later. The functionality is very simple and similar to most self powered speakers. For its size and sound it is worth the price.
