有幸碰到三对ATLAS SD-370A的驱动头,自己留下一对玩,剩下两对出给喜欢的烧友。 
全部4.2欧
这样就能发声了,到时可以这样验货
目前我自己的玩法是这样的,15寸JBL号角低音,ATLAS出600-3200,JENSEN RP-107出3200以上
ATLAS SD-370A驱动头规格:
Models SD-70 and the patented SD-370A (U.S. Patent #7,760,501) provide maximum power conversion with low-amplifier output to fulfill high- intelligibility and sound-penetration requirements. Model SD-70, rated at 58 Watts RMS, Model SD-370A, ratedat 100 Watts RMS,Either unit can be used with most horns or reflex horns equipped with the industry standard 1 ⁄ " – 18 thread pattern. 型号SD-70和SD-370提供了最大的能量转换依靠低功率输出一个完全符合高清晰度和声音穿透力的需要。型号SD-70功率达到58W,型号SD-370功率达到100W,两者都可以用大部分的号角和他们匹配。 SD-370A for high-powered systems. SD-370A是个高能量系统 Drivers are equipped with a non-fatiguing, self-aligning sound chamber assembly containing a 2 3/4” phenolic diaphragm with a nominal impedance of 11 Ohms. 驱动器配备了一个不会疲劳并且会自动对中的腔室,安装了一个11欧姆的2又3/4英寸的酚醛电木振膜。 Replacement head assembly, Model K-70GB is available for field replacement of Model SD-70; Model K-370A for SD-370A.

请看美国高烧友对这个驱动头的评价:http://www.diyaudio.com/forums/multi-way/239472-new-ideas-k-55-pd-5v-compression-drivers-11.html
I am convinced that Atlas has
two even more impressive drivers. If the goal is to use a good
tractrix or Seos from about 800-1200hz on up, these drivers are killer. I think
they approach Goto level bass performance to below 100hz. Honestly.
The SD-70 and SD-370.
我确信那个ATLAS有两个甚至更多的驱动头。如果目的是有一个好的曲线或者模拟800-1200及以上,这些驱动头是个杀手。
我想他们已经接近GOTO的水平低音性能到100HZ下。老老实实说,就是SD-70和SD-370.
这些美国高烧友都是玩西电WE555,和GOTO单元的主http://www.diyaudio.com/forums/multi-way/239472-new-ideas-k-55-pd-5v-compression-drivers-2.html
如果有兴趣看完整篇贴子,你就知道他们在干什了。
我买回来的价格也不是很高,卖出的价格是1200元每对驱动头,联系电话13829156535,姚
这是在国外拍卖的价格,是单只驱动头的价格
