During the development of fenestria, PMC’s engineers undertook extensive research into the effect of vibrations on audio performance. In particular, the analysis of vibration and its impact on sensitive components within crossover circuits led to fenestria being fitted with the very best, British made, capacitors and non-inductive German resistors, designed to eradicate internal micro-vibrations which have a negative impact on the performance of the speaker. This technology was employed in the fact signature series, resulting in new crossovers, mounted on military-grade circuit boards, that are populated with the same key hand-selected components employed in the fenestria, with the positioning of each component carefully calculated to minimise unwanted interference. Each crossover is tuned to provide optimum performance of the system with improvements in the resolution of micro-details, soundstage presentation and an increased tangibility in the critical midrange/vocal region.
I'm going to be That Guy and ask why they don't throw away all the coils and capacitors and go active. Imagine the micro-details then!
