The 10NTLW3500 represents the last add on to the dual gap family, which is the state of the art of 18sound components and technology for high power, finest quality applications.
The dual gap technology comes directly from the Tetracoil motor structure and applies its benefits to a wider frequency band, making the 10NTLW3500 capable of working perfectly both as a woofer and as a midbass with unmatched power and the lowest distortion/pressure ratio in this dimension.
Optimized thermal conductivity allows great power handling (up to 1600 watts), the extremely balanced Bl shape together with the ultra linear suspension, maximizes Spl keeping the lowest intermodulation distortion in the market, giving the 10NTLW3500 the amazing capability of reproducing a deep and full low end, together with perfect clarity mids. Both magnetic gaps are also equipped with two separated single demodulating rings. 
This unique features, makes the 10NTLW3500 the perfect component for highest quality line arrays and two way systems without the need of a midband dedicated component.
