The Master Index of "The Flawed Physics and Misunderstanding of Low Frequencies"
Seeing as this thread got resurrected, I figured I'd attempt to provide some closure.
This thread was started on February 13, 2011 by an individual going by the user name of "ymalmsteen887". From the start, it was a little bizzare. From there, it turned into probably one of the weirdest, if not THE weirdest threads in the history of AVS due to either a profound level of ignorance, or a rather interesting troll. (The jury is still out)
However, as has been obsserved, there is a wealth of useful information which can be gleaned from the many posts of dedicated AVS members who tried in vain to help this individual. So that their efforts might not be forgotten, I offer to you, dear reader, this master index of the most helpful posts in this thread.
If you want to learn some good fundamentals of how speakers work, why they sound different, and considerations in the attempt to reproduce accurate sound, I recommend that you first hover your mouse over "ymalmsteen887"s name, and select "Block Member" in the drop-down list. He will only confuse you.
If, however, you are a bit more adventurous, then by all means, read what he has to say. But be warned, if a clinical trial were done, it would likely be proven that reading ymalmsteen887's posts will add more than a couple gray hairs to your head. That being said, the sheer oddity of this thread cannot be grasped if you ignore his posts.
Please do not respond to ymalmsteen887. This is an old thread, and he has not been active on this forum for over a year. In fact, I'm pretty sure all of his posts on AVS were in this thread alone. I believe this index will both help new members to find some good foundational information on audio theory, and put a nice little ribbon on this thread.
With that, I humbly recommend this thread be locked away into the annals of AVS history.
