In stock

This very compact, wide-range speaker is well-suited for both voice and music.  With an acoustically dampened treatment on the engineered paper cone, it is a broad, flat frequency response.  Its motor is made of a unique dual neodymium magnet design, which "turbo-charges" the speaker to provide high sensitivity and high power handling.

  • 30 Watts of program power handling
  • High output sensitivity for increased per-watt output 
  • High-compliant, natural rubber surround
  • Black powder-coated steel basket
  • Maximum Energy (ME) dual neodymium magnet

Note: This speaker has a tall surround for high excursions; therefore, grille placement cannot be flushed to the front of the cone.
