Ok, since getting the SWATMOS idea from
, i decided to test it out. So, the idea is based on the discovery that the wides play different content as a result of how you activate them. You can do that two ways:
1. Use just one set of height speakers for a 9.1.2 setup.
This results in objects only playing from the wides.
2. Use no rear surrounds for a 5.1.4 +wides setup.
Now the wides play a mix of objects and surround sounds, but not exactly the same content as neither the "pure" wides, nor the "pure" surrounds.
At the same time as this was discussed in the "wide appreciation thread", i upgraded my non-DTS:X Denon 5200 to a 6200. I WAS going to sell the 5200, but the aforementioned suggestion got me fired up. So to test this out, i had all three Atmos AVR's connected to the following:
First AVR setup in a 9.1.2 setup for "pure wides" playing ONLY these wides, all others silent.
Second AVR setup in 5.1.4+W setup for Wides/Sur1 playing ONLY these wides, all others silent.
Third one setup in a 9.1.2 setup for "pure" surrounds, playing only these surrounds, all others silent.
I could now play any combination of these 3 sets of speakers, and listen to differences. I used severeal of the Atmos demo tracks and also the Bailando music video, as music har repetetiv and consistent sounds.
As the Bailando video was a very good example to use, let's do that:
Pure wides: can be silent 5-10 seconds at a time, and then play one distinct sound, very "digital". By that i mean it starts and ends very sudden, no ambiance, no echo, just very "dry", presise sounds.
Wides/Sur1: this is a lot more like normal surround sound, much more sounds, and you can hear some percussions and chorus playing. And these sounds have more ambiance, not so "on/off", and more "smooth".
Pure surrounds: these play even more chorus, and now you can hear guitars, and other sounds. Very clear difference when muting and un-muting these versus only the two sets of wides.
So clearly not the same content in these 3 sets of channels.
Also, with just the two sets of wides playing, i could not only hear pannings side to side, but also front to back! I was surpised by this, but i noticed this in several of the tracks.
And after enabling all speaker for the full 13.1.8, one thing is very noticable : the presision and placement of sound coming from the front corners, between my fronts and pure surrounds, are much better. Now playing Leaf, Amaze, or films like Gravity, it is the the best i have heard from my setup!
I will update the first post with the new setup, wich is actually a lot simpler, despite now including 3 Atmos AVR's. (And still my Yama Multi-zone-active-speaker-switch).
Here is a pic of the new "SURROUND ARRAY". From left in pic:
Pure Wides @50 degrees (floorstanders)
Wides/Sur1 @70 degrees
Pure Surrounds@85 degrees
Sur2/Rears @ 110 degrees.
Surround back(out of pic) @150 degrees.
