Beschreibung
The Reference RS75 is a 3" (8cm) midrange driver from Dayton Audio. These models are known for their ability to outperform "boutique" drivers, despite their comparatively inexpensive price range. They captivate with their understated but highly technical design and high-resolution sound quality with low distortion. Made and developed in the USA, they feature an aluminum frame, aluminum cone and rubber surround. Special features include the low-distortion motor system with copper ring, copper cap and aluminum phase plug.
