More Speakers - More Volume... Ahmm NOT!

In the knowledge of many people,more Speakers = More volume,the double Decibels,or whatever... Not really...

This Article should be read after you read one of the previous Articles called "Explaining The Watts" because we are also messing with Watts here,and i'm sure i'll hear someone saying 2x100w = Double Louder than 1x100w.

More Speakers = The same volume,but why they sound louder?


Picking up a 5Channel system instead of a 2Channel just because you think it would be louder if it has 5 Speakers is a big mistake,except if you need a surround system for Movie Watching or Extended Stereo for Music Listening and better Room Covering.

If you have a 5Channel Power Amplifier that really can output 100w in 5Channel Program and only two Speakers,if you add another three you basically have about the same volume as two.

More Speakers even if they are weaker and can output less Decibels than a Stereo (2Channel) Pair of Speakers,they are "Covering" and filling the room with Sound better than two,and giving a more "Complete" feeling,while they output about the same SPL as two with the same specs driven by the same amount of Power.

That's because each more speaker will add one or maybe two Decibels more,so if a single speaker is outputting 100db at 1 meter,adding another one that is also outputting 100db,the total SPL will be about 101-102db max at 1 meter,but at the ear will sound louder not because two are dramatically louder than one,but because as i explained two will fill the Room better than a single one.
