Description

  • 4-inch, fiberglass former, edgewound aluminum voice coil
  • 700W continuous program power handling
  • 101 dB Sensitivity
  • 60 Hz – 2 kHz Frequency range
  • Shaped Shallow Triple-roll damped surround
  • Inverted dust cap
Very high efficiency and extended linearity are special features of this mid-bass transducer. Very efficient heat dissipation is ensured by a radiator that is part of the basket design. The aluminum voice coil offer a properly aligned Q factor and a very high sensitivity. A specially designed Shallow Triple-roll surround guarantee a very low midrange distortion. Fiberglass former voice coil, polycotton suspensions and treated cone provide the very high power handling.
