This Tang Band W3-871SC has a black embossed steel frame, silver coated paper cone, rubber surround and solid aluminum phase plug. Famous as one of the smoothest 3" full range speakers on the market. Shielded for A/V applications.

The W3-871SC has identical parameters to the W3-871B, but the W3-871SC is magnetically shielded.

Highlights:

• Aluminum phase plug also acts as a shorting ring for lower distortion.
  
• Underhung voice coil improves control for lower distortion
  
• Impressive efficiency (86 dB 1W/1m) for such a small driver
  
• Unique surround and large centering spider keep the diaphragm linear well beyond the rated xmax value
