In fact the better room correction systems offering higher resolution are specifically designed to be used in the manner sdurani describes -- multiple measurements from multiple points in the room.

If you have not heard the difference that MultiEQ-XT (or the even more tweakable PRO variant or even more precise MultiEQ-XT32/Pro ... http://www.audyssey.com/technologies/multeq/flavors) can make with even a VERY high end system it is frankly astounding. I was more than a little skeptical before I heard the very very nice Wisdom system but it is really a night & day sort of difference that makes the whole experience noticeably better NO MATTER where you sit / stand in a properly running system in even a very large room.

The key is that with the high resolution filters and a high quality system the software is truly calculating both the frequency related problems AND the time domain issues then applying filters that allow the most performance for all measured positions -- http://www.wisdomaudio.com/products_sc-1.php

The "guts" of the algorithm are in the chipset that Audyssey licenses and from discussions with technical people at Wisdom and some of the other respected audio manufacturers the certification that Audyssey goes through is pretty thorough so the potential variation IN THE SOFTWARE is eliminated. Of course that still leaves lots of room for a whole lot of other digital noise to impact the rest of the chain, to say nothing of the various limitations of the analog part of the reproducing equipment so it still makes a lot of sense to get as a high quality system as one can reasonably afford...

And Audyssey is not alone in this style of room correction -- the Trinnov system is also strongly oriented toward making the whole '3D sound space' as realistic for as many listeners as possible: http://www.trinnov.com/technologies/loudspeaker-room-optimization/concept-6/ A very similar philosophy is also the foundation of the RoomPerfect system from Steinway-Lyngdorf http://www.steinwaylyngdorf.com/technology-and-innovation/roomperfect (I believe KRK was forced to cancel their Ergo product based on the same technology -- http://www.krksys.com/manuals/ergo/KRK_ERGO-Brochure.pdf) Although Anthem chooses not the highlight the "3D" aspects of their system the fact is they also build their system with MULTIPLE room measurements in mind: http://www.anthemav.com/downloads/ARC-1_PDS.pdf



In short folks that DO NOT UNDERSTAND what these systems actually achieve are perhaps the single greatest impediment to manufacturers pushing even more mathematically complex implementations down into the more affordable products. Of course it does not help that so few people even visit a retail showroom to actually LISTEN to the very noticeable improvements capable with with such a system but that is a whole other issue...

I will add that the I am not sure if there isn't a problem with marketing these systems as "auto room correction" -- there has been research that shows "flattest response" is not really the goal. Listeners judge the best sounding system to be not necessarily closest to spectrum neutral but that which gives the most pleasing spectral balance and factors in the room gain: http://seanolive.blogspot.com/2009/11/subjective-and-objective-evaluation-of.html and also http://dagogo.com/lyngdorf-rp-1-roomperfect-room-correction-device-review

Finally, in the context of what these means for firms like Outlaw, that frankly NEED a competitive advantage if they are to remain relevant, I would hope they somehow "partner" with firms that care more about advancing the overall technology than being a "me too" audio firm. Seems very likely that in an increasingly "venture capital" driven economy the potential for creating a real physical product that builds off the something like Open Source Software could be a real game changer -- http://en.wikipedia.org/wiki/Digital_room_correction#Open_Source_Implementations
