I just got this speaker delivered to me. I only got a little taste of how it sounds when I tested it out. Didn’t even have my volume at half and the bass sounded incredible. I have a wedding to dj February 10th I can’t wait to use it. I also have a eon718s I’m going to replace it when I save up the money and get another 918. Great bass speaker I recommend
