Maximum linearity and inductance symmetry for extended mid-band clarity
Ideal for two-ways and line array applications
The 8NTLS2000 represents the latest 18sound technology for high quality, low distortion applications. The Tetracoil technology maximize benefits in terms of thermal dissipation and Bl symmetry, making the 8NTLS2000 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 8NTLS2000 the perfect component for highest quality line arrays and two way systems, thanks also to its 700 watts power handling capabilities.
