Even if all 30 DTS:X speaker locations were to be activated, it wouldn't matter because neither DTS:X nor Atmos have a speaker location at the top of the screen, so the upper centre IMAX channel will always be reproduced as a phantom image. That won't change when DTS goes past its 11.1 speaker limit because full reproduction of IMAX Enhanced soundtracks only requires a 7.1.4 set-up.
Thanks for the clarification. That's a huge dealbreaker then. I don't see any reason why DTS/iMax couldn't support a discrete CH if it's in the physical layout and the processing power is there (apart from the fact that only a minority of users could benefit from this, as it requires 12 processing channels. Auro 3D does this fine on the X8500H).
Either they provide the original Atmos (full-range) with objects, or they provide 12 discrete pre-rendered channels with CH if the AVR supports it. I have zero interest in their hybrid 7.1.4 + phantom CH.
Atmos and DTS:X might not have a CH position, but they have FH so you can phantom a perfect CH from that, or position a CH object very accurately there (where it should be, exactly in the middle, above the screen). So arguably a full range Atmos/DTS:X mix using FH to position a CH object would provide better results than their "iMax Enhanced" monstruosity, which is entirely unnecessary from a technical point of view and doesn't bring anything that couldn't be delivered with Atmos or DTS:X.
I'll try one title when I have a chance, but there is no way this will sound good in my setup. Their phantom CH will be in the middle of the screen, not above it, and forward, so basically in my head.
I guess it might work better for those with an AT screen and a C in the middle of the screen, or with C above the screen.
If it does work well, I'll report back, but I'm not holding my breath.
