@gene @shadyJ I have a question about the 1723 2V's "Extreme Bassaholic" rating. According to the site one of the Extreme criteria is to have the SPL output @ 4 meters be >= 117dB @ 25Hz. The listed CEA-2010 2m 25Hz burst test shows 109.1dB, and adding +6 to convert that to a corner loaded 4m value makes it 115.1dB. Did I misread how the CEA-2010 values should be converted? Also FWIW the way I'm calculating the 31.5-63Hz measurements is adding together the 31.5, 40, 50, and 63Hz values, dividing by 4 for the average, and adding 6 for the 4m corner-loaded conversion. The reason why I'm running the numbers is to see if some other model subs just barely make it into one room category or another or if they're in a solid median. Also because MY room size is bordering around 3000ft^3 in between size categories.
