Here's the link: https://forum.audiogon.com/discussions/time-coherence-how-important-and-what-speakers A lengthy but worthwhile read. Highly recommended! It's hard to believe that it's 16 years old. Still very relevant. Though I think Jim's last flat facia coincidental drivers just might be a marvelous response to some of those now old criticisms. |
The conclusion from some of the previous discussions is that concentric drivers with the tweeter located coaxially mounted within the midrange driver is the best way to achieve a more consistent soundstage. Some have commented on the Meadowlarks and pre-concentric Thiel speakers to have a sound that is sensitive to listening position. I am very puzzled that we don't have any good concentric drivers available on the market. If Thiel could do it, I don't see why either ScanSpeak or Seas could not. In my own design, with separate tweeter and midrange, the sound balance is also sensitive to listening position. There is one way to fix this is to lower the xover frequency from the tweeter to the midrange so that the dispersion characteristics of the midrange and tweeter are more evenly match. The problem is the tweeter has to play lower so that could add to tweeter distortion. Some of the new tweeters from ScanSpeak could play lower but the less expensive tweeters may not be. This affect is more prominent with first order filter vs. higher order filter design. |
