Peerless by Tymphany DX25TG59-04 1 Fabric Dome Tweeter

This DX family tweeter features a 4 ohm 25 mm ferrofluid-cooled voice coil, a damped silk diaphragm with large surround roll to produce a low resonant frequency, and a ferrite magnet motor which adds heat sinking for power handling capacity. The faceplate features recessed mounting holes to minimize reflections.
