Can you point out an example of someone who has been led to think that by being exposed to a discussion about the differences between SQ,
SQL, and SPL drivers?
That makes as much sense as thinking that a pure SQ-oriented sub with sound perfect in just any 'ole install or believing that a straight-up SPL sub will bang as hard as physically possible for the driver/power combination regardless of what kindof box in which it's installed.
Either of these lines of thinking are simply ludicrous and I cannot personally think of an instance of someone considering one or the other with any degree of seriousness at all much less as a result of someone's commentary about this product or that being competent for use in an SQL application.
Consequently the argument about whether or not 'SQL' is even a valid term is equally as silly IMO.
