12” Neodymium Midbass, 4” voice coil, 600 W, 99 dB

 

12NMB600_copy

KEY FEATURES:

  • 99 db 1W / 1m average sensitivity
  • 100 mm high temperature sandwich voice coil
  • 1200 W AES program power
  • Vented neodymium magnet assembly with massive heatsink
  • Double aluminium demodulating rings for lower distortion and improved heat dissipation
  • Silicone spider

Application : High power midbass

The 12NMB600 loudspeaker combining good linearity and efficiency with high power handling capabilities. It features 100 mm aluminium voice coil, silicone spider, aluminium die cast frame, and vented neodymium magnet structure. The used inside double demodulating rings ensure ultra low distortion. The massive heatsink improves the cooling of the magnet structure, which reduce power compression. 12NMB600 is suitable for application as LF driver in compact 2- way boxes, and horn loaded systems.

1. AES standard. Power is calculated on rated minimum impedance. Measurement is in 65 L box enclosure tuned 63 Hz using a 40-400 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.
