Hello,
The coaxial driver in the 8351A was introduced already in 2009 when the 8260A was published. That means it had its 10 year anniversary this year. It is the 1st generation coaxial driver we have made. Since that, we have learned a lot when it comes to designing a high performance coaxial driver, and in 2017 we launched the 2nd generation coaxial in the 8331A and 8341A monitors. Now, in the 8351B and 8361A we are launching the 3rd generation coaxial driver which is a completely new design compared to the original coaxial. Please notice this is not the same as the physically smaller coaxial driver used in 8331A and 8341A monitors.
-neodymium magnet vs. ferrite which reduces the mass of the driver
-1 inch tweeter vs. 3/4" which leads to higher SPL capability but also larger bandwidth (up to 43 kHz)
-larger voice coil to provide more power handling as well as help to drive the cone from an optimum position
-lower woofer to mid crossover (470 Hz to 320 Hz)
-higher mid to tweeter crossover (2600 Hz to 2800 Hz)
-better overall performance, lower distortion
-better manufacturability and tighter tolerances
8351A and 8260A monitors will be discontinued which means the 1st generation coaxial will not be produced any more (of course spare parts are still available).
8351A上的同轴单元沿用自2009年8260A发布时的单元，今年已经是它的十周年了。它是我们研发的第一代同轴单元，在那之后，关于设计高品质的同轴单元，我们已经得到了很多教训，于是在2017年我们发布了8331A和8341A上的同轴单元。现在，与8351B和8361A一起我们发布了第三代同轴单元。相比最初代同轴单元，它是全新的设计。请注意，（虽然外形相似），这个和8331A和8341A上看起来更小一些的同轴单元是不一样的。
- 新同轴单元采用钕磁铁，老的采用铁氧体，减轻了单元的重量
- 1英寸高音单元 vs 3/4英寸高音单元，能产生更大的声压级并有更好的高频延展（高达 43 kHz）
- 更大的音圈，提供了更好的能量控制，并能从更好的位置驱动纸盆
- 更低的低中频分频点（从470Hz降低到了320Hz）
- 更高的中高频分频点（从2600Hz升高到了2800Hz）
- 总体上更优秀的性能和更低的失真
- 更加精良的设计工艺和更小的公差
第一代同轴单元将随着8351A和8260A停产而停产。（当然维修用的更换部件还是有的）
