George L. Augspurger

Biographical Sketch George L. Augspurger received his M.A. degree from UCLA, followed by postgraduate work at Northwestern University. After working in sound contracting and television production he joined James B. Lansing Sound, where he served as Technical Service Manager and later as Manager of the newly formed Professional Products Division. In 1970 Mr. Augspurger left JBL to devote full time to Perception Inc., a consulting office specializing in architectural acoustics and sound system design. Mr. Augspurger is a fellow of the Acoustical Society of America, a fellow of the Audio Engineering Society, and a member of the United States Institute for Theatre Technology. His name is familiar as the author of numerous articles and technical papers, mostly dealing with loudspeaker design and application. His double-chamber speaker enclosure described in the December 1961 issue of Electronics World is still a favorite of amateur speaker builders. Today, there are more than 100 installations of custom monitor loudspeakers designed by Mr. Augspurger in professional recording studios throughout the world. He contributes regularly to the Patent Reviews published by the Journal of the Acoustical Society of America and reprinted by the AES Journal.

期待下文。

这个问题yulihua烧友等之前在论坛已经有较好的论述，当然，看看老外“砖家”怎么说会有意思。我自己觉得烧友要求高一些，阻尼系数400以上为好。考虑到反电动势的影响，阻尼系数还是大一些，比较让人放心，甚至用负阻抗的放大器来推低音。

就一张？还没说完呐！刚刚开头[s:98] [s:98]
不过从“The higher damping factor,the more accurately the speaker is controlled and the better the performance.is this right?"这句话看，肯定不是这回事[s:97] [s:30]

皇冠对于阻尼系数的解释：






Though technically more complex than this, Damping factor
is usually thought of as an indicator of how tight an amplifier
will sound when powering bass speakers. A speaker's driving motor is a coil of wire (called a voice coil) mounted within a magnetic field. As this coil of wire moves within the field a voltage
will be induced in the voice coil. If resonant motions of the speaker are not sufficiently short circuited by the amplifier, the speaker output
can have an over accentuated or "boomy" bass sound.
From a technical measurement stand point, Damping factor is the ratio of the rated speaker impedance
to the amplifier's output impedance. Low output impedance is the consequence of the amplifier having substantial negative voltage feedback taken from its output terminals. Properly designed negative feed back not only corrects for output voltage errors induced by the speaker but also produces other benefits:

• Low distortion
• Low noise
  (hiss)
• Flat frequency
  response
