Test & measurement
Selenium's D220Ti-8 is a high quality compression driver offering excellent efficiency and low distortion. It is recommended for use in studio monitors, stage boxes, and sound reinforcement in small to medium rooms.
Selenium D220Ti 1" Titanium Horn Driver 8 Ohm 1-3/8"-18
The Selenium D220Ti-8 horn driver's diaphragm is formed from pure, rigid, light, and extremely thin titanium (0.025 mm). To avoid stress and distortion, the suspension has specially designed reinforcement. An injected-molded phase plug is optimized to eliminate undesirable phase cancellations.
The D220Ti-8's ceramic magnetic assembly effectively concentrates flux in the gap, and highest motor strength efficiency is achieved through the use of FEA (Finite Element Analysis). A voice coil manufactured in CCAW (Copper Clad Aluminum Wire) and wound on a polyimide former assures great stability and thermal resistance, and the moving assembly has a perfect auto-centering characteristic that makes replacement easy if required. Standard 1-3/8"-18 TPI screw-on mounting.
