Штаб-квартира фирмы American Acoustic Development находится в г. Роли (штат Северная Каролина), а ее шеф Фил Джонс (Phil Jones) — британский дизайнер — раньше работал в компании Acoustic Energy и был создателем знаменитой модели AE1, принесшей славу фирме.

Колонки AAD E30 с габаритами всего лишь 11 х 11 x 15 см оснащены единственным динамиком с алюминиевым куполом (9 см) с частотным диапазоном 130 Гц — 20 кГц. На пути сигнала кроссовер не предусмотрен, и АС могут "выдержать" до 150 Вт.

Отлично подходит на роль тыловичка. Для всех колонок серии Е предусмотрен вариант настенного монтажа (фирменный кронштейн - опция).
