How much PA does your guest count actually need?
Two speakers for 150 people, or four speakers and a pair of 18s? The guest-count math behind every quote, with the exact rigs in our three packages.
The most common question we get is not about brands or wattage. It is some version of: "There will be about 150 people. What do we need?" Here is the same math we run before every quote.
Start with three numbers: guest count, room volume and program. A seated dinner for 200 needs less system than a dance floor for 80. Outdoors, with no walls to hold energy, add roughly a third more headroom. Humidity, and in Miami there is always humidity, eats high frequencies over distance, so throw matters as much as loudness.
The rule of thumb we actually use
A pair of quality 15-inch powered speakers covers conversation plus music for about 150 guests indoors. The moment dancing is the point and not the background, subwoofers stop being optional. Bass is what a floor feels. Tops alone just get harsh when pushed.
| Guests and program | System |
|---|---|
| 100 to 200, pop-up or lounge | 2 speakers on stands |
| 200 to 350, dancing | 2 speakers + 2 x 18-inch subs |
| 350 to 500, full production | Multi-zone system + crew |
Those three rows are, not by coincidence, our three event packages. They exist because the same three rooms kept showing up: the daytime pop-up, the wedding with a serious dance floor, and the production that needs speech, dinner and party zones at once.
Where people overspend
Renting four speakers for a room that needs two does not make it sound bigger. It makes it harder to tune. Spend the difference on a second 18-inch sub instead: perceived loudness lives in the low end, and a floor that feels full at a lower volume is a floor where people can still talk at the bar.
And one thing we will always say out loud: do not let weak gear hold back your sound. A cheap speaker driven into its limiter all night is the most expensive thing at the party.

Frequently asked questions
How many speakers do I need for 100 guests?
For background music and speeches indoors, two powered speakers on stands is enough for 100 guests. If people will be dancing, add one or two 18-inch subwoofers.
Do outdoor events need a bigger system?
Yes. With no walls to hold the energy, plan on roughly a third more headroom than the same guest count indoors.
