Alternative/Current Model:
10NW750

Features

  • 97 dB SPL 1W / 1m average sensitivity
  • 51 mm (2 in) voice coil
  • 350 W AES power handling
  • Extremely balanced BL shape for maximum SPL
  • Optimized thermal conductivity
  • Maximum linearity and inductance symmetry for extended mid-band clarity
  • Ideal for two-ways and line array applications
The 10NTLW2000 represents the latest 18sound technology for high quality, low distortion applications. The Dual Gap technology comes directly from the Tetracoil motor structure and uses the same concept to maximize its benefits in terms of thermal dissipation and Bl symmetry to a wider frequency band, making the 10NTLW2000 the perfect component both as a woofer and a midbass.
Dual gap motors linearize inductance and the perfect balance we reached between the motor and the ultra linear suspension allows both very high excursion and extreme precision in the mid band with the lowest intermodulation distortion in the professional market.
This features, together with its extreme low weight make the 10NTLW2000 the perfect component for highest quality line arrays and two way systems, thanks also to its 700 watts power handling capabilities.
