Having a 11.2 installation since 2009, based on a DSX speakers configuration, with Klipsch KL650/KS525 THX Ultra 2 speakers (and SVS PB13 U subs) I'm having similar concerns. As in the very beginning I was using the Audyssey DSX processing (with Dolby IIx to add back surrounds), but since the arrival of the exceptional DTS Neo X 11 Cinema processing , this is the one I exclusively use. Now with the arrival of this new "object audio" generation, what should be done as far as speakers configuration is concerned...
My analysis is that all this will depend on what will be the next standard concerning the number of channels built in the new processors. Will it be 11.2 as today, or shall this evolve into 13.2 or even 15.2? Why so?
Today if one considers the Dolby Atmos scheme of implementing speakers, it is essentially based on surround speakers positioned above ear level completed by a "certain" number of ceiling - or VOG type of - speakers... In my opinion, this won't ever be implantable into a HT environment... particularly into an already existing one.
So we have to consider what could be other options... and this is where the Auro 3D implementation comes into consideration as it consists of 3 layers : ear level, above ear level (45°), VOG. And today in its' 11.1 configuration this consists of a "standard" 5.1 (2) + 4 heights (above L+R and SL+SR) + either 1 VOG + 1 BS or 2 VOG (and no BS).
And it also seems that at some point, an (evolution ?) of the actual DTS Neo X 11 could be tweaked to address this type of configuration, as far as somewhere in the processor's channel configuration, each channel's position could be identified as such.
All this means that the present generation of 11.2 processors actually has the capability to handle this next generation of object audio. Even in a 13.2 configuration of speakers with a "standard 7.1 (2) + 4 heights + 2 VOG, as both the 2 BS and 2 VOG could be driven in parallel...
So this is where a 13.2 processor comes to make sense, as with a 13.2 processor, all 7.1 (2) + 4 heights + 2 VOG speakers could be individually addressed and though adequately calibrated...
Now why 15.2? As a purist I have become accustomed to the Wide speakers, which IMHO do really fill the gap between the Front (ear level) speakers and the Surround speakers, singularly in a HT environment, this is why, again as a purist, I would hate to have to lose the Wide speakers... though this 15.2 processor solution that I would support as it would give us the possibility to individually address and calibrate all speakers in a 7.1 (2) + 2 Wide + 4 Height + 2 VOG speakers. A dream?
So before we see how many channels will be standard in the new generation of processors, I'd wait before taking decisions, as far as what to do with speakers. Anyway this is what I do here.
Have a nice Sunday,
