will a 100 watt 5.1 sound system be enough for a 3000 square foot hall with about 200 people in there?

Question

I have the Dell 5650 5.1 surround sound

what does that mean? 60db?

Answer 1

might be a bit weak near back of room

but a lot depends on speaker quality

Answer 2

Honestly no That 100 hundred watts is divided up among the 5 speakers totaling 20 watts per speaker 20 X 5 =100 or 5 divided into 100 = 20. now if the audience is to remain quite they can hear the audio signal BUT if its a party you will need alot of power. If you want 100 watts blasting out each of the 5 speakers you will need a 500 watt amplifier (asuming that the speakers will handle 100 watts a piece ) Its easer to have 4 speakers rather than 5 that way the amp will divide the remaining 100 watts . (100 divided by 4 = 25 ) into the 4 speakers totaling 125 watts per speaker. Your amp wont have to work as hard . You can tell if its over worked by how hot it gets. The amp will get fairly warm during use but thats normal If you can smell a funny elecrtical sent in the air the amp its over heating and will shortly burn out and become useless .

Answer 3

dB is short for decibel. The decibel unit is commonly used to measure sound levels.
60 dB is about the sound level of the inside of an office or restaurant.

A home surround sound stereo isn't even any good for ambient music in a room that size with 200 people, unless mono sound is an option, or all 5 speakers are placed close together. (And the result will still be poor.)

You will definitely want to borrow, or rent a PA system. For talking any decent PA system will work. If you want to play music & reach the sound levels of a dance club (about 100dB) with bass in the music you'll need a professional PA system.

Answer 4

Depends on what you want to use the sound for, just as a background, or for actual music playing. For the latter, it wont be enough, I suggest getting a better sound set up, for just ambiance, it might be, although I would not go for anything under 450-600 watts.

Answer 5

suggest you have a chat with. someone who knows exactly, what can be done, because your sound system, you are talking about, will sort of fade out due to the ROOM VOLUME {SIZE} i'm no expert, but some people would NOT hear a blessed thing, specially if having hearing trouble! YOU, got a compagny. that is called SOUND ON STAGE, if not look in phonebook, for your version

Answer 6

if you just want ambient music to refine the chatting noise, that'll be fine. but the system won't be enough to create a club sound or a decent theatre sound. check if your system reaches 60 db at mid-volume. :)
