NB-4 2-Pack

This bundle includes two pairs of Power Acoustik NB-4 tweeters, four units in total, built around the same niobium dome technology that has made the NB series a long-running favorite for shallow-mount tweeter upgrades. Instead of a conventional voice coil, each tweeter uses a niobium rare earth transducer, a design that can't burn out from sustained power the way coil-based tweeters do. That construction supports a genuine 120 watt RMS rating per tweeter, with a polypropylene diaphragm for accurate, detailed high-frequency output and a built-in crossover that keeps low frequencies out of the tweeter's path. The NB-4's four-way mounting system, flush, angle, surface, or swivel, gives you more placement options than a typical two-way tweeter, so it fits dash corners, kick panels, or pillars across different vehicles. With a 250 watt max rating per pair and 500 watts across the full bundle, this pack works well for upgrading a factory system or filling out a two-vehicle install without buying tweeters twice.
