This member of the OT tweeter family utilizes two Tymphany technologies to deliver exceptional sound quality: the ring radiator patent, and the central waveguide patent. This model features a 19mm 4 ohm voice coil, mounted in a neodymium magnet motor. The tweeter also features a rear chamber to create extended low frequency response. This compact tweeter without faceplate is ready for installation into compact systems.
