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, 200 W, 8 Ω
  • 20 cm (8") speaker with high-performance neodymium drive system
  • Coated, deformation-resistant, kevlar-reinforced, low-resonance paper cone
  • 50 mm (2") 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)
  • Octagonal basket for minimum distance between the speakers, especially for line array systems
  • Diecast aluminium basket and a low weight of 1.52 kg only
