GRS PT6816-8 Planar Tweeter

The GRS PT6816-8 Planar Tweeter delivers exceptionally clear and detailed high-frequency reproduction, making it an outstanding choice for audiophile-grade loudspeaker projects. Engineered for discerning listeners, this planar driver brings a level of transparency and airiness to the top end that conventional dome tweeters often struggle to match. Its low-distortion design ensures that every nuance of cymbals, strings, and vocals is rendered with remarkable precision and realism.

This tweeter is ideally suited for use in high-fidelity home audio systems, studio monitors, and custom speaker builds where accurate treble response is paramount. Whether you are designing a two-way bookshelf speaker or a multi-way floor-standing system, the PT6816-8 integrates seamlessly to provide a wide, immersive soundstage. Its planar diaphragm offers excellent dispersion characteristics, ensuring consistent performance both on and off axis.

Technically, the PT6816-8 features an exceptionally low voice coil inductance of just 0.02 mH, which contributes to its superb transient response and extended high-frequency extension. With a sensitivity of 94 dB SPL (1m/2.83V) and an 8-ohm impedance, it is efficient and easy to drive. The total Q factor of 4.57 and mechanical Q of 6.19 indicate a well-damped, controlled behaviour. Its compact dimensions (200 × 65 mm overall, with a 175 × 41.9 mm cut-out) allow for flexible mounting in a variety of enclosures.

In summary, the GRS PT6816-8 Planar Tweeter offers a compelling combination of clarity, efficiency, and technical refinement, making it a superb upgrade for any serious loudspeaker design.
