6.5 ” Neodymium Midrange,  1.75 ” voice coil, 150 W, 97 dB

 PRELIMINARY DATA

  6NM150_p

KEY FEATURES: 

  • 97 db 1W / 1m average sensitivity
  • 44 mm high temperature voice coil
  • 300 W AES program power

 

Application : Power midrange speaker 

The 6NM150 is high efficiency, high power midrange neodymium loudspeaker , specially designed to use in 3 way boxes and line array systems. It features 44 mm aluminium voice coil, vented aluminium die cast frame with powerful neodymium magnet structure, which achieved very light weight of the speaker.

MOUNTING INFORMATION 

1. AES standard. Power is calculated on rated minimum impedance. Measurement is in 9 L box enclosure tuned 70 Hz using a 100-2000 Hz band limited pink noise test signal applied continuously for 2 hours.
2. Program power is defined as 3db greater than AES Power Capacity.

* Linear Mathematical Xmax is calculated as: (Hvc - Hg)/2 + Hg/4 where Hvc is the voice coil depth and Hg is the gap depth.
