I noticed on the thread for this GTG on another forum that there has been significant questions raised about the legitimacy of the comparison between the Chase SS-18.2 and the Seaton Submersive HP.
The points of contention that have not been addressed yet are:
1) How positioning of the subs differed so much (one dual opposed pointing left-right, and the other forwards-backwards) as to create the disparity in the measured frequency response.
2) Apparently different levels of EQ to achieve their measured in-room responses.
3) Supposedly different volume of playback for each (with the SubM supposedly higher playback), with the implication being that the volume disparity resulted in higher scores for the SubM.
As for 1), the subs are oriented differently, it's true, but it seems they were placed in the same geographic location, and the orientation was forced by the height of the SS-18.2 (so as to not interfere with the screen).
For reference, the SS-18.2
And the SubM HP
Can this different orientation be the cause of the great difference in measured response between the two subs, as is clearly insinuated on that other forum's thread?
As for 2), I think desertdome's explanation of the EQ'ing process overall and for each individual sub seems legitimate enough for me. Perhaps someone can condense the multitude of responses about this to break it down to a nuts-and-bolts explanation of how they came out so different after EQ, and whether or not this was somehow unfairly skewed towards benefiting the SubM.
As for 3), weren't all of the clips in the subjective ratings portion of the event done at matched playback levels for each sub? Or did I miss some mention of greater levels for one sub or the other during the ratings part of the GTG? The only mention of higher volumes I heard was for the Open Range scene that was demoed unscored.
I've read this thread top to bottom, as well as the one on the other forum. Sorry if this is rehashing stuff, but I saw a bunch of speculation and questioning of results, and not a single repository of answers to refer to.
