• 98 dB SPL 1W / 1m average sensitivity.
• 900 W AES (rms) power handling.
• 3.5”, 88 mm Tetracoil dual voice coil.
• Eighteen Sound has Ultra linear suspension behaviour for excellent sound clarity.
• Symmetric flux density and inductance behaviour.
• Low noise forced air cooling design.
• Extremely balanced BL shape for maximum SPL.
• Optimized thermal conductivity.
• Ideal for two way and line array loudspeaker designs.
• The Eighteen Sound 15NTLW3500 represents the latest technology for high quality, low distortion applications.
• Dual Gap technology comes directly from the Tetracoil motor structure and uses the this concept to maximize its benefits in terms of thermal dissipation and Bl symmetry to achieve a wider frequency band, making the 15NTLW3500 the perfect component both as a woofer and mid bass.
• Dual gap motors of Eighteen Sound linearize inductance and deliver the perfect balance between the motor and the ultra linear suspension allowing both very high excursion and extreme precision in the mid band with the lowest intermodulation distortion in the professional audio market.
