AT在10寸及以上大尺寸低音单元的三明治已经标准化三款， 10C772510KAP , 12D772510KAP, 15f1022510KAP .
在10寸，12寸，15寸的单元，三明治对比与PP盆，最大的区别在于低音的表现。KA（混合音圈骨架）和三明治结合，即使在振幅很低的情况下，低音表现也是很有力，干净，精细，音场体现精确。
大口径单元的阻尼特性和Qms是至关重要的。AT的三款三明治单元，在设计上明显的提高了单元的Qms。从12寸的12D77看其Qms 为5.5 ，而在同等尺寸的12B77 的PP盆的Qms 仅为2.5。这势必大幅度提升单元的前沿特性，喇叭瞬态好，带来的效果就是速度的极度提升，即使ETON的12寸的Qms 也仅为3.52 。
最难得是在提高Qms 的前提下，AT的12D77通过Qes的设计， Qts 仅为0.25 ，保证了喇叭后沿特性的优异。这从T/S参数上解释了喇叭的品质。
12D77的低频延伸明显提高，与15寸单元对比来看，可以在相对于较小箱体容积下，达到平坦的对等低频。

The KA system is implemented in the Sandwich cone drivers and is a mixture of Kapton and Aluminium voice coil bobbin. This means, the driver acts as a pure Kapton voice coil driver, as long as the voice coil is within its linear working area. It also presents a very low mechanical resistance, which allows the driver to play bass with authority, even at low levels.

All drivers are naturally generously ventilated, under the spider, from voice coil gap and not least through the pole piece, allowing the whole moving system to travel fast and freely, without any compression.

喜欢搭配陶瓷的可以参考TG网上一款ACCUTON C30-6-024 ,C173-6-191E+AT 10C77 。
对AT 10C77 的评价是：所用过的最好的一款10寸低音单元，合适的效率，分频简单，在低音力度和细节即使在小功率下也表现得突出。唯一的缺陷就是喇叭太重。毕竟这是大磁钢，厚铝框架，华斯导磁板特殊设计。
Audio Technology 10C77-25-10-KAP bass driver has been reported in detail here. Not much to add except that in its category*, this is the best 10" bass driver I've had.......................

troels在设计山寨WILSON AUDIO ALEXIA ，念念不忘AT 10C77 2510KAP :认为10C77 不二的选择，10寸里边的最佳单元。
Bass: I couldn't think of anything better for the Jenzen ATS than the 10C77-25-10-KAP.

丹麦AT 10寸碳纤维三明治。

Polymer Logic Mk. 2 is the updated version of the now discontinued Polymer Logic with a long list of refinements. Built on a completely new platform that is the result of continuous research in materials and resonance control. Mechanical distortion is reduced to a level that is at the limit of the measuring capability of instruments.

Most listeners find that the Logic Mk. 2 transports them into the recording studio where the original event took place. This loudspeaker has incredible energy and fills even very large rooms with effortless dynamics. It is capable of perfectly recreating massive, thunderous crescendos. And yet, reveals the natural and rich harmonic bloom and delicate textures of instruments. Music just sounds more vivid and has more vitality. And of course it has the enormous and atmospheric soundstage that Polymer Audio loudspeakers are known for.

At the heart of this loudspeaker is a pure diamond cone midrange (not just diamond dust or particles, but a solid, 100% pure diamond cone) mounted on a heavily damped structure composed of multiple layers of materials. This midrange is suspended in a separate floating enclosure that is immersed in a liquid viscoelastic compound that remains liquid for the life of the product. This means that none of the enormous energy being generated by the dual 9” woofers reaches the midrange driver during delicate music playback.

This system also has a unique new crossover that allows steep slopes but limits the overall component count, which is key for musical purity. The crossover network is made from pure copper foil and no film is used. This is the most authentic approach and leads to a lifetime of reliable use.

This is an ambitious product indeed that is the result of obsessing over every single detail. Please contact us to arrange an audition.
