Oberton 18NSW700 pic

KEY FEATURES:

  • 77 mm (3") high temperature sandwich voice coil
  • 1400 W AES program power
  • Powerful, vented neodymium magnet structure
  • Double aluminium demodulating ring for lower distortion and improved  heat dissipation
  • Double silicone spider assembly for improved excursion control and linearity
  • Water protected cone with Carbone fibers
     

 

APPLICATION: Power bass  

The 18NSW700  neodymium bass loudspeaker is specially designed to deliver high impact bass response, with exceptional high power capacity. It incorporates a 3", 34 mm long sandwich voice coil, double silicone spider assembly, paper cone with Carbone fibers and die cast vented aluminium frame. Powerful, vented magnetic structure which reduces power compression with double demodulating rings. The result is high efficient transducer for precision bass applications, with the ability to handle high excursion with low distortion. It has very low Mms and Le which ensure very fast bass reproduction

1. AES standard. Power is calculated on rated minimum impedance. Measurement is in 192 L box enclosure tuned 43 Hz using a 40-400 Hz band limited pink noise with peak factor 9 dB 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.
