KEY FEATURES:
- 97 db 1W / 1m average sensitivity
- 115 mm ( 4.5”) high temperature sandwich voice coil
- 3200 W AES program power
- Vented neodymium magnet assembly with massive heatsink
- Double aluminium demodulating rings for lower distortion and improved heat dissipation
- Double silicone spiders for improved excursion control and linearity
- Water protected cone
- Epoxy anti-corrosion coating of top and back plates of magnet structure
PART NUMBER: 11118N0108
Application : High power bass
The 18NXB1600 neodymium bass loudspeaker is specially designed to deliver very high impact bass response, with exceptional high power capacity. It incorporates an 4.5" sandwich voice coil, double silicone spider assembly, kevlar paper cone and die cast vented aluminium frame. Powerful, vented neodymium magnetic structure with massive heatsink and double demodulating rings reduced power compression. The result is high efficient transducer for subwoofer applications, with the ability to handle very high excursion with low distortion and reduced thermal power compression.

1. AES standard. Power is calculated on rated minimum impedance. Measurement is in 180 L box enclosure tuned 43 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.
