Dayton Audio DW3-1053SC 3" Full Range Driver The Dayton Audio DW3-1053SC 3" full-range has an attractive pincushion style frame, edge-damped poly cone, flat spider, and rubber surround. The underhung 7/8" voice coil provides nearly ideal cone control to deliver linear travel and wide frequency response. With extremely smooth, extended frequency response you can expect an easy transition to tweeters in multi-way designs and a remarkably full sound in full range systems. A neodymium magnet with black plastic heat sink fins minimizes weight making the DW3-1053SC perfect for use in line arrays or portable speakers.
