В отличие от классических конуса и купола, высокочастотник ATF относится к категории «планаров», в которых за звукоизвлечение отвечает плоская мембрана микронной толщины (такой же материал Dupont Kaladex PEN используется в электростатах). Находясь в магнитном поле нескольких мощных неодимовых магнитов легкая пленка с токопроводящей дорожкой, колеблется с частотой входящего электрического сигнала, в данном случае – высокочастотного. Площадь мембраны не в пример больше, чем у купольных ВЧ-динамиков. Широкая полоса воспроизведения и выдающиеся динамические показатели позволили инженерам компании назвать ATF «твитером высокого разрешения». Эта звуковая особенность роднит Preface с электростатами последних поколений (Summit, Spire, Purity), поэтому новинку можно смело рекомендовать как для самостоятельной, так и для совместной работы с электростатами в мультиканальных аудиосистемах MartinLogan.
