How do you listen to music? Speakers, headphones, which types, etc. Reply #25 – 2013-01-15 18:46:21 Quote from: mzil on 2013-01-15 17:27:09I agree with the author's AES paper which points out that MTM designs have response errors which are "not predicted by a simple lobing error analysis" that most speaker designers utilize.Nothing new about a speaker company dissing others while touting their own fix for the problems of the world. At some point you are bound to see phrases like: " sets new standards for a speaker in its price class." (in quotes because it came from the author, but something like that appears in the literature of almost any speaker beyond the system-in-a-box class) If there was a fatal flaw in the motivation of constraining the vertical dispersion, I suppose the author would have addressed it, rather than ignoring it.If the paper truly justified the death of D'Appolito designs, that surely would have happened over the 17 years since it was published. Thiele-Small concepts in speaker design took off like wildfire and dominated the industry in just a couple of years after publication.I'm not saying MTM is perfect, but it is a viable design layout with virtues that have stood the test of time.
