Absolutely inadequate for desiphering the subjective sound quality yes - all we can deduce is that the system has a maximum sensitivity of 98db/w at best, and quite possibly less. As do many fine loudspeaker systems.

All loudspeaker systems are compromises. Placing the 515G in that manner at least reduces the effect of it's backwave causing a deep phase cancellation from the rear wall reflection. As I say - compromises - none neccessarily more moronic than the next.

I'd like to see the system designer provide some explanation as to his design choices - that would give this thread a sense of direction it sadly lacks at the moment. The only thing I would say is that is it not likely that the positioning of the 515 will have a long term effect on the suspension and result in sag?

I do not know about the sensitively. The 515G with +4dB might go up 103-104db. The sensitively is not what I would care looking at the picture, thought I hardly see in there 98db. Sure, all loudspeaker systems are compromises but some of them are not compromised but wrong. You have to stop to think in term of phase cancellation but in term of Sound. Connect right and left speakers in opposite phase and position them vertically – you will perfectly mimic what this guy does. The reasons why I am so bold about it because I did it in past during my period when I read all those Allison fantasies about injection of back-phase signals into listening space.

Yes, I agree that if system designer provide some explanation as to his design choices it would be more valuable observation but he is Japanese with all sonic negative consequences (in fact the open-bass-horn would be very typical for the "Japanese Sound").  Also, I insist that is the level at which a playback is being used by the system owner is an indication of the system accomplishment. So, looking at that the Brazilian guy does, his overriding everything with his favorite digital toys, without any senses of any regards to Sound....  to me it is a very objective indication of what is going on there.
