21.2 Channel Surround Sound

Yes, we have done it – we have created a 21.2 channel surround sound. I say again, we have created a 21.2 channel surround sound. Just think about that a moment…..the industry standard is still only a 5.1 channel surround sound. The next most used format is 7.1 channel (sometimes 7.2) and yet Premium Audio has done it again and created something way beyond home theatre!

Mathmatically, Premium Audio’s 15.2 channel surround sound is 3 times the size of the standard 5.1 channel surround sound (not counting the subwoofer which is simply doubled)!

Now Premium Audio has tripled the 7.1 channel surround sound format (not counting the subwoofer which is simply doubled)! In order to triple the subwoofer part that would be .3 (meaning three separate subwoofers used) and would be unnecessary even by our standards.

21.2, so where do all the speakers go and why? Recently we mentioned 19.2 channel surround sound. 21.2 builds on this by adding an additional pair of side speakers, only this time they are at or almost at ceiling height and aim downward. This is our final take on Dolby Atmos. The reason this is our final take on Dolby Atmos is because this surpasses what even they have to offer.

We offer two slight variations to 21.2 channel surround sound:

  1. add a second pair of side speakers aiming down from the ceiling.
  2. add a second pair of side speakers at the same height as the regular side speakers are. Place these near them too. With this variation a super large room would not loose the sound that is to play out of the sides of the film no matter where you choose to sit.

To learn how to wire this up, if you do not how how already, check out this book: Customize Your Home Theater 5.1 channel to 15.2 and everything in between. Then apply the same concepts to grow this to a 19.2 channel surround sound. From there add a speaker selector to where the side speakers attach to the surround sound receiver. Plug two pairs of speakers into the speaker selector and make sure both speaker inputs are on to get sound out of both pairs of speakers at the same time. If you do all of this you will have a 21.2 channel surround sound system.
