NTR12-3018D

Professional PA Speakers
of the CELESTION NTR series with neodymium drives represent where we are today with PA speaker technology. Developed with the aid of analysis methods and state-of-the-art computer simulation, these speakers provide an excellent radiation with lowest harmonic distortions at a very low weight.
Professional PA bass-midrange speaker, 350 W, 8 Ω
  • 30 cm (12") speaker with high-performance neodymium drive system
  • Deformation-resistant, kevlar-reinforced, low-resonance paper cone
  • 75 mm (3") heat-resistant voice coil
  • Especially developed thermal management of the drive system for preventing thermal compression and overheating
  • Multi-roll rubber surround for an excellent linearity and progressive control in case of excessive cone excursion
  • Very low harmonic distortion (THD)
  • Diecast aluminium basket and a low weight of 2.6 kg only
