KEY FEATURES:
- 99 db 1W / 1m average sensitivity
- 77 mm high temperature sandwich voice coil
- 900 W program power
- Vented neodymium magnet assembly with massive heatsink
- Triple aluminium demodulating rings for lower distortion and improved heat dissipation
- Double silicone spider for improved excursion control and linearity
PART NUMBER: 11115N0908
Application : High power woofer
15NB451 loudspeaker combining good linearity and efficiency with high power handling capabilities, with use of 77 mm voice coil and double 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. 15NB451 is suitable for application in a wide variety of enclosure types and particularly as LF driver in 2- or 3- way boxes.

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.
