NEW 18” Woofer, 4” voice coil, 1300 W, 97.5 dB

 

18xb1300

KEY FEATURES:

  • 97.5 db 1W / 1m average sensitivity
  • 100 mm high temperature sandwich voice coil
  • 2600 W AES program power
  • Powerful, vented ferrite magnet structure
  • Double aluminium demodulating ring for lower THD and improved heat dissipation
  • Double silicone spider for improved excursion control and linearity
  • Water protected cone (front)

 

Application : High Power Bass

The 18XB1300 ferrite bass loudspeaker is specially designed to deliver very high impact bass response, with exceptional high power capacity. It incorporates an 4” sandwich voice coil, double silicone spider assembly, carbone paper cone and die cast vented aluminium frame. Powerful, vented ferrite magnetic structure with double demodulating rings which 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.
