The Selenium D220Ti-OMF-8'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 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" 2-bolt/3-bolt mounting.
