It's a 3 way WMMTMMW config, where the woofers are in the cabinets on the back, and the MMTMM in the horn. The woofers are powered by a class D amp in the foolter, the rest by a tube amp that stands behind it. Joseph Crowe is a known and reputed designer. He build very vintage style speakers, but on measurements and science based and his designs work as intented (says his reputation). And i also like those designs way more than those extra glossy towers posted above (independent of sound quality).
