Description

Beyma 12MI100 12" 450 Watt AES 8 ohm Mid-bass/midrange Speaker

The low-mid frequency Beyma 12MI100 transducer offers three main points of interest: a high efficiency (5.1 %), an extremely linear frequency response and a low harmonic distortion. These characteristics make it suitable for high quality sound reinforcement systems, especially for live applications. Moreover, its versatile design allows it to be used as the low-mid loudspeaker in a two ways system or as an strictly mid-frequency transducer in a three ways system. Beyond its frequency response advantages, this loudspeaker offers more: it takes profit of the improvements achieved in our low frequency-high power transducers. Thus, it incorporates a high quality voice coil and a large magnetic assembly to provide efficient heat dissipation. Thanks to this design concept of strongness, the 12MI100 reaches a considerable power handling (450 WAES).

 Features:

  • Very high efficiency (5.1 %)
  • Extremely linear frequency response
  • Low harmonic distortion
  • 3' edgewound aluminium voice coil with polyimide fiber glass former
  • Large magnetic assembly to provide efficient heat dissipation
  • Designed for high quality mid-frequency reproduction

Materials:

  • Voice coil: edgewound aluminium wire with high temperature bonding strength. Polyimide fiber glass former able to withstand high temperatures.
  • Cone: light and stiff paper cone to provide good mid- frequency response.
  • Surround: treated cloth to mechanically equalize the frequency response.
  • Spider: cotton spider.
  • Metal parts: anti-corrosion coated back plate designed to resist aggressive environmental conditions.
  • Basket: specially designed die cast aluminium basket to avoid disturbing resonances.
  • Magnet: high Curie temperature ferrite
