18 Sound 8NTLW2000 Low-Frequency Driver
The 8NTLW2000 is a premium 8-inch neodymium low-frequency driver engineered by 18 Sound to deliver powerful, precise, and reliable audio performance. Designed with advanced Tetracoil technology and optimized motor architecture, this driver combines high power handling with exceptional clarity and low distortion, making it an ideal choice for professional audio systems requiring robust mid-bass output.
Innovative Tetracoil Ultra-Linear Motor Technology
At the heart of the 8NTLW2000 lies the proprietary Tetracoil design, which features four separate voice coils housed in two gaps. This unique dual-gap motor structure allows for exceptional thermal dissipation, reducing power compression and maintaining performance under high power loads. The Tetracoil motor delivers a balanced BL curve and symmetrical inductance characteristics that drastically minimize distortion and provide ultra-linear response across the frequency range.
High Power Handling and Efficiency
The 8NTLW2000 offers a continuous power handling capability of 700 W with an AES rating of 350 W. This power capacity ensures the driver can handle demanding audio workloads in professional environments without risk of failure or distortion. Its sensitivity rating of 97.5 dB guarantees efficient sound pressure output, allowing for clear, impactful sound reproduction with minimal amplifier power.
Extended Frequency Response with Low Distortion
Covering a frequency range from 70 Hz to 4500 Hz, the 8NTLW2000 is versatile enough for mid-bass and lower midrange applications. Its curvilinear cone, triple-roll surround, and advanced motor design work in tandem to reduce distortion, ensuring clean, accurate sound even at high excursion levels. The driver maintains controlled cone movement for precise, detailed audio reproduction across its entire frequency span.
Lightweight, Durable Construction
Weighing significantly less than comparable drivers, the 8NTLW2000 incorporates a neodymium magnet and an aluminum voice coil to balance power with lightweight design. The cone is treated for water and UV resistance, making it suitable for both indoor and outdoor use. This durable construction enables the driver to maintain reliability under rigorous touring and installation conditions.
Optimized Mechanical and Thermal Design
The large 51 mm (2.0 in) aluminum voice coil with a 13 mm winding depth enables efficient heat dissipation, crucial for maintaining consistent performance during extended high-power use. The neodymium magnet and 8.5 mm magnetic gap depth contribute to enhanced motor force and improved linearity. Together, these design features minimize power compression and mechanical fatigue over time.
