在国外的评论是参考ATC 的的SM75-150S超级大馒头。原文如下:
The ATC SM75-150S is a very expensive proposition now。
A comparable Audio Technology driver would be the excellent C-Quenze 15 H 52 12 06 SDKM which is a dedicated midrange or alternatively if you don't require a 91dB sensitivity then the C-Quenze 15 H 52 06 13 SDKAM is 89dB and has a flatter response. Price wise the AT drivers are cheaper than the ATC.
In terms of comparisons they're both strong drivers when used correctly but I prefer the AT's for their more refined character and very bandwidth performance. My main issues with the ATC are its limited bandwidth and pretty ragged response which pigeon holes it into pretty much one crossover configuration - approx 500hz to 3Khz with fairly steep filters such as 24dB/oct or greater. The AT on the other hand is nicely flat across its usable range and can extend happily down to 150hz and all the way up to 5Khz and beyond. This flat and extended pass band is great for low order filters and general crossover design flexibility. As for the dark quality sometimes associated with poly cones, the AT's have none of that I've heard. I do think the debate over the contribution to colouration from cone material is often overstated. I've used many including magnesium, poly, paper, ceramic, cloth, aluminium and so on. My observation is that good drivers have more in common than not regardless of cone material.
