This completely goes against Dr. Floyd Toole's book. His findings did show that the lateral reflections are perceived as preferable over all (wider apparent source width), but not the rest of the reflections. You're incorrect.
Wrong on both counts.
First, you're making the assumption about the relative importance of ASW that are unjustified.
Second, let's assume
arguendo that one desires lateral reflections. One can get the desired lateral reflections with narrower-directivity speakers by "overtoeing" them. (Aiming them such that their axes cross in front of the listening position.) That does not contradict anything Dr. Toole has written or studied. Fact of the matter is, his (published) ASW tests simply didn't use any such speakers in that configuration.
(And point of fact, doing so
also attenuates late reflections relative to the direct sound even as it promotes early (contralateral) reflections, simply because the sound has to travel farther - and has already hit one boundary - than in other sets.) Simple geometry that any 6th grader should understand, there...
Your interpretation of what I wrote, found below, is indeed incorrect, as it's not even fancifully based on the text I put in front of you.
The room can affect the sound more than the speakers, but the room can be fixed; flawed speakers***
Who wrote anything about "flawed" speakers?
It's takes some really odd logical leaps to go from my formulation
"***pick speakers that are designed to perform well under [the properties of the room one intends to place speakers in]"
to your botched remix:
"flawed speakers."
What kind of twisted logic did you employ to go from "speakers designed to perform well under specific conditions" to "flawed speakers"? I'm genuinely curious to see you spell it out.
For instance, is the
Snell XA "flawed" because it offers options to tailor its output the room (and listener preference)?
And point of fact, the room
cannot "always be fixed." Some of us have aesthetic sensibilities, or partners with aesthetic sensibilities, that preclude turning rooms in our homes into an audiophool's padded cell paradise.
(room correction can sometimes do more harm than good, so that isn't a definitive fix).
While that's obviously true, it's obvious not a cogent reply to the text I actually put in front of you:
"modern room correction systems are
very good at eliminating some placement-caused problems, such as boomy upper bass from speakers "too close" to room boundaries." [emph. added]
Chosing a speaker that performs well based on the listening room is a flawed approach. Instead one should start with a great pair of speakers and place them in a good room or one that has been fixed with proper treatment placement
My approach will result in both better sound and greater domestic tranquility than yours. But if you think you need to live in a padded cell (with glass sidewalls?)...I'm not your housemate, so what do I care?
