KEY FEATURES:
- 100 db 1W / 1m average sensitivity
- 77 mm high temperature voice coil
- 1000 W program power
- Vented neodymium magnet assembly with massive heatsink
- Triple aluminium demodulating rings for lower distortion and improved heat dissipation
- Silicone spider
- Water protected cone (front)
PART NUMBER: 11112N0608
Application : High power woofer
12NB450 loudspeaker combining good linearity and 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. 12NB450 is suitable for application as LF driver in compact 2- way boxes, and small stage monitors.

1. 2 hours test made with continuous pink noise signal with Crest factor 6 dB, within the range Fs-10Fs. Power calculated on rated minimum impedance. Loudspeaker in free air.
2. Program power is defined as 3db greater than 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.
