Frequently Asked Questions
How many watts do I need for a PA system?
For a live band indoors, plan about 8 watts per person. For outdoor events, multiply by 2.5 to account for sound dispersion.
Do I need subwoofers for a PA system?
Subwoofers are recommended for live bands and DJ events to reproduce bass frequencies. Speech and acoustic events generally do not need them.
