Test Bench: The New TW 104.28 N/Ag 1.1" Soft Dome Tweeter from RS Speakers

RS Speakers is a new Italian brand recently introduced by SICA Altoparlanti, to enter the high-end home transducer market. The driver on this Test Bench is a 28mm soft dome tweeter that features a treated silk dome directly bonded to the voice coil, with a wide roll surround and an unusual wire screen to keep the damping in place beneath the dome.
