18” Woofer, 4” voice coil, 1000 W, 98 dB

 

18XB700_pic

KEY FEATURES:

  • 98 db 1W / 1m average sensitivity
  • 100 mm high temperature sandwich voice coil
  • 2000 W AES program power
  • Powerful, vented 220 mm magnet structure
  • Aluminium demodulating ring for lower distortion and improved heat dissipation
  • Double silicone spider for improved excursion control and linearity

 

Application: High Power Bass

The 18XB700 bass loudspeaker is specially designed to deliver high impact bass response, with exceptional high power capacity. It incorporates an 4`` sandwich voice coil, kevlar paper cone, a powerful, vented 220 mm magnetic structure, die cast vented aluminium frame which reduced power compression, and double silicone spider assembly. This results in an incredible high efficient transducer for subwoofer applications, with the ability to handle 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.
