I've heard that certain songs and noise/tests can be good at revealing particular flaws in a design or driver or crossover. I've seen some recommended listening lists, but I haven't noticed much mention about what specifically to listen for problem-wise and I'd like some guidance on other listening test using noise or songs or whatever else.
Are there some songs or clips that are good at revealing frequency peaks/valleys or generally unnatural frequency response?
Is there anything I can listen to that'll be really good at revealing distortions?
Is playing pink noise while moving around and trying to listen for obvious "shhweeiiiiw whoosh" of comb-filtering and notches a good way to "test" for phase/alignment issues, or are there more effective listening tests?
Are there any other major speaker problems that can be heard and narrowed down through some careful listening tests?
What are some important pitfalls to lookout for when trying this?
I think I'd like to become a more effective listener with a better ear (though I'm also a little afraid that ignorance is bliss). Teach me your ways. Empower me to put off buying measuring equipment and learning to use it for as long as possible.
