NEW  10” Neodymium Midbass, 3” voice coil, 500 W, 96.5 dB

 

Oberton Loudspeaker 10NMB500R

KEY FEATURES:

  • 96.5 db 1W / 1m average sensitivity
  • 77 mm aluminium, high temperature voice coil
  • 1000 W AES program power
  • Vented neodymium magnet assembly with massive heatsink
  • Double aluminium demodulating rings for lower distortion and improved heat dissipation
  • Water protected cone (front)
Application : Power midbass speaker
The 10NMB500 neodymium loudspeaker is combining good linearity and efficiency with high power handling capabilities, with use of 77 mm aluminium voice coil. It features curvilinear paper cone with water protection (front), aluminium die cast frame with vented neodymium magnet structure. The double aluminium demodulating rings on the magnet structure reduce distortion and inductance and improve transient response. The massive heatsink improves the cooling of the magnet structure, which reduce power compression. 10NMB500  is suitable for application as LF driver in compact 2- way PA boxes with 1” HF driver.

1. AES standard. Power is calculated on rated minimum impedance. Measurement is in 30 L box enclosure tuned 60 Hz using a 50-1000 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.
