18 Sound 12NTLW3500 12" High Performance Neodymium 4000W Program Power Speaker

Technologies

• The 12NTLW3500 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 12NTLW3500 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 (only 4.8 Kg) make the 12NTLW3500 the perfect component for highest quality line arrays and two way systems, thanks also to its 1800 watts power handling capabilities.
