And that regarding SQ description, you are essentially saying that because they were not set-up on an even plane, ranking one sub tighter or cleaner than another on the whole isn't necessarily true?
And that if each was set-up to their best potential with for example an AS-EQ1 Subwoofer EQ, there could have been a different outcome on not only SPL and FR but also the articulation and tightness of each sub?
I'm just trying to understand. This is certainly an important notion if true, and should be known.
And I'm not suggesting the bros claimed any of this. They reported the findings in their room the way they intended. And regardless of this being true or not I learned a lot about these subs and companies in a way that has never been done before, and kind of experienced that fun purchase with them. Thankfully not the re-packaging.
To be clear, I didn't mention EQ in my post. Subwoofers are not plug and play audio hardware. The first step in setting one up is to change the subs and/or the listening positions location, followed by distance/phase correction and level matching. PEQ is the last step and should be used minimally for optimal performance.
To illustrate my point, I posted a graph of the same exercise that I conducted, although the exercise I conducted was not intended to compare the SQ and peak SPL differences.
Now, imagine that I posted subjective comments and peak SPL meter readings of these 3 subwoofers using the same music and movie snapshots as were used in this shootout.
The problem is that the different frequency responses are of the same subwoofer. Since frequency response is what we hear and what the rumble tone produces and what the meter reads, I would have posted a completely different set of subjective comments and peak meter readings describing the same subwoofer.
Although it's a worthwhile exercise that I've conducted many times, it explains how a room influences what we hear and what can be done about that. Most people believe that this is a very important aspect of optimal performance when using any subwoofer.
That debate aside, using only the first plug and play response to evaluate the subwoofer would certainly not tell someone who reads the evaluation how the subwoofer might sound in his room or vs another subwoofer.
