The Nakamichi N-T20 is a pair of high-performance 20mm KSV dome tweeters specifically engineered to add crisp, vibrant high-frequency performance to your car’s sound system. In car audio layouts, standalone tweeters like the N-T20 are mounted high up—such as on the dashboard, A-pillars, or door sails—to pull the "vocals" upward so they don't sound muffled by your feet.
