The 12NTLX3500 represents the latest 18sound technology for high quality, low frequency applications. The Dual gap motor structure maximize its benefits in therms of thermal dissipation and Bl symmetry, making the 12NTLX3500 the perfect component for high quality, low tuning, compact subwoofers.
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 12NTLX3500 the perfect component for highest quality compact subwoofers, thanks also to its 1200 watts power handling capabilities.
