12” Neodymium Midbass, 3” voice coil, 450 W, 101 dB

 

12N_copy

KEY FEATURES:

  • 101 db 1W / 1m average sensitivity
  • 77 mm high temperature voice coil
  • 900 W AES program power
  • Vented neodymium magnet assembly with massive heatsink
  • Triple aluminium demodulating rings for lower distortion and improved heat dissipation
  • Silicone spider

Application : High Output Midbass with extended midrange

12NXL400 loudspeaker combining high efficiency with high power handling capabilities, with use of 77 mm aluminium voice coil and silicone spider. It features aluminium die cast frame with integrated triple demodulating rings and vented neodymium magnet structure. The massive heatsink improve the cooling of the magnet structure, which reduce power compression. 12NXL400 is suitable when fast and precise midbass reproduction is required.

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.
