Default Loudspeakers for party

I am a newbie and need help with audio for a party.

- there would be 200 people in hall
- there won't be loud music, but everybody should be able to hear well ( there will be over 50 kids !!)


questions :

- will a 400w amplifier be enough ?
- how many speaker / woofers would be required ?
- should the speakers be placed on floor or on a chair/table ?
- where should they be placed ? diagonally across the hall ? next to each other ?

2x600@4 Ohm

4x15 inch +1 inch throat driver cabs. Over long dimension put 2. On the opposite side put another 2 facing the empty distances between the former 2.

Use tripods, height of horn about 2.2 m from floor, little downangle towards midhall if possible.

Could you give dimensions of the room?

the power required from the amp to get enough SPL (sound pressure level) also depends on the sensitivity of the speakers. For example, cheap speakers usually need a bigger amp to compensate for the lower sensitivity.

The number of speakers required depends on the capabilities of the speakers (sensitivity, power handling etc), size of the room, available budget etc.

The high frequency units should at least be placed above earheight, higher is prefereable, because when there're many people in front of the HF driver these frequencies won't be heard further away from the speakers, in my experience.

When placing multiple speakers in the same room be sure they work together well. Cancellation of certain frequencies at some places in the room can happen, as well as delayed sound. Usually 'ideal'/good placement is found just by experimenting, there're too many factors that have to be considered, so it's hard if not impossible to simulate. Just trial and error.


Many things just depend on the situation, you can only find out by experimenting. That's what I've learned at least...

regards

Erwin
