B&W CM9

摘要

I admit to double-checking the price of the CM9 because it appears to offer such a lot of hardware for the money. As well as being one of the largest speakers here, it has four drivers including B&W's highly regarded FST midrange unit whose woven Kevlar cone, rather than having a conventional roll surround, is swaged at the edge and rests on a ring of foamed plastic which operates in compression. This novel arrangement improves the dissipation of cone vibrations but limits the available cone excursion, making the FST unit unsuitable for reproducing bass frequencies.
