Power Acoustik NB-18 - High-Sensitivity Super Tweeters for Crisp High Frequencies
The Power Acoustik NB-18 Super Tweeters are precision-built for audiophiles seeking accurate, high-frequency sound reproduction in compact form. Designed with a lightweight polypropylene dome, these micro dome tweeters minimize distortion while maintaining clarity at peak output levels. This material allows for smooth response curves, especially in the upper-frequency range, delivering a spacious and open sound stage across any vehicle setup.
At the core of each NB-18 lies a niobium magnet structure—a rare-earth element valued for its magnetic stability and thermal resistance. This component supports consistent crystal-clear highs and boosts sensitivity, reaching up to 97 dB SPL, making them ideal for both SPL and SQ builds. Whether you're upgrading your factory tweeters or integrating them into a custom audio configuration, the NB-18 adds pronounced detail without over-amplifying harsh treble.
Installation is seamless thanks to the compact design, allowing surface-mount or angled-mount versatility for flexible placement on A-pillars, dash corners, or sail panels. A built-in high-pass crossover network ensures only the cleanest high frequencies are routed to the tweeter, effectively blocking mid and low frequencies that introduce distortion or cone fatigue.
Key Features:
- Polypropylene dome construction for high-frequency accuracy
- Niobium magnetic assembly for low heat distortion and extended frequency response
- 200 watts peak power handling (100W RMS)
- 97 dB sensitivity ensures powerful output without excess power demand
- Built-in 6dB/octave high-pass crossover
- 4-ohm impedance for universal amplifier compatibility
- Mounting hardware included for flexible installation
The NB-18 Super Tweeters are purpose-built for car audio systems that demand tight, defined treble, whether part of a full component system or integrated into a factory upgrade. These are not your average tweeters—they're engineered for those who expect clarity without compromise.
