NTR12-3018D
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.
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
