Yesterday I DJ'd a wedding that required the total volume to be below 80 db. Speaking volume is approx 65 db, so you can imagine the challenges that were presented.
The neighbors did not want to come over and enjoy the festivities, so they rather call the police at 7:15 pm. Now understand that in Collier County the noise ordinance is 92 db until 10pm. The wedding party did not want bad blood, neither did I.
We were able to party for 3 hours on the dance floor to Watch Me, Cha Cha Slide, Cupid SHuffle etc and everyone had a blast.
Using the JBL PRX series speakers, I can achieve high or low volumes with the clarity and feeling that I need. Hiring a DJ with quality equipment allows for adjustments on the fly without sacrificing sound quality.
