The 8NTLW2000 represents the latest 18sound technology for high quality, low distortion applications. The smallest Tetracoil motor structure of the family uses the same concept to maximize its benefits in terms of thermal dissipation and Bl symmetry to a wide frequency band, making the 8NTLW2000 the perfect component both as a woofer and a midbass. Tetracoil 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 8NTLW2000 the perfect component for highest quality line arrays and multi-way systems.
