In Reply to: RE: Question: Do the "speaker guys" ever tell us that they're selling phase incoherencers? posted by rick_m on August 01, 2007 at 13:50:21
And it was all thoroughly covered in The Wood Effect (1988). I blame the magazines for neglecting this aspect; the old Audio used to do speaker reviews in which the phase distortion was measured *and published* in easy form, not the rather more confusing (albeit revealing) Melissa plots of today.

Sorry, couldn't resist Clark...
Yes, I've read them. Heyser did a good job yet I don't recall them being particularly useful, maybe I'm just too superficial of a reader. I subscribed to Audio from ~1973 until they folded. Guess I mostly read magazines for interest and entertainment and largely ignore them when purchasing equipment.
Are you saying that you described a temporal metric that had good alignment with what listeners experienced? If so maybe I WILL have to spring for a copy.

Nothing however about temporal metrics -- saving that for a later day.

The definitive statement on polarity written 20 years ago. It ignores simple impulse tests, it ignores many EIA standards in regards to microphones and headphones already in publication, it ignores the more recent AES 26 and other standards. It ignores new media such as laser discs, MP-3, and such, as one would expect from a relatively ancient and not well researched document. Now we are to await further details in an upcoming article, details of which can not be shared until publication. Clark's attempt to enlighten the general public shows his true colors: money before sharing of knowledge.
Such hubris
