Power Acoustik NB‑2: 3-Way 200W Car Tweeters with Niobium Magnet & Polypropylene Dome

The Power Acoustik NB‑2 tweeters are designed for automotive audio systems that require reliable high-frequency reproduction without unnecessary complexity. Built around a 3-way acoustic design and engineered for precision, these 200-watt component tweeters deliver clarity at high volumes and responsiveness across a wide frequency range of 5 kHz to 25 kHz.

Precision Audio Engineering for High-Frequency Reproduction

At the core of the NB‑2 is a 1-inch polypropylene dome tweeter, selected for its low mass, high sensitivity, and consistent sound performance. This diaphragm material supports the wide dispersion of upper-mid and high-frequency content without distortion, which is critical for achieving spatial openness and imaging in car interiors.

Unlike budget tweeters that introduce harsh peaks or brittle tones, the NB‑2 is optimized for sound staging and detail clarity, delivering a refined response curve that doesn’t overpower vocals or midbass elements.

Advanced Magnetics with Rare-Earth Materials

A key differentiator of the NB‑2 is its Niobium rare-earth ferroelectric transducer magnet. Known for its magnetic stability and efficiency, Niobium allows the tweeter to maintain accuracy under dynamic load without introducing signal fatigue. This ensures the driver retains linearity even at higher volume levels—ideal for listeners demanding fidelity from factory system upgrades or aftermarket builds.

On-Board High-Pass Filtering for Signal Protection

Each unit includes an onboard high-pass crossover, configured at 6 dB/octave, to filter out low-frequency content that can cause distortion or premature driver fatigue. This ensures that the NB‑2 operates within its intended frequency band, maximizing performance while protecting your investment from clipped or overdriven signals.

Mounting Versatility for Custom Installs

With support for flush, surface, and angled mounting, the NB‑2 adapts to a range of vehicle interiors. Whether you’re upgrading factory dash positions or customizing A-pillar placements, the tweeters include installation hardware for reliable placement and directionality.

Key specifications, including a cut-out diameter of 1.75 inches and a shallow mounting depth of 0.75 inches, provide compatibility with most vehicle makes and models.
