GRS PT6825-8 Planar Mid/Tweeter

The GRS PT6825-8 Planar Mid/Tweeter represents a sophisticated solution for achieving pristine high-frequency reproduction in high-fidelity audio systems. As a planar magnetic driver, it offers distinct advantages over conventional dome tweeters, delivering exceptionally low distortion and remarkably wide dispersion characteristics that create a spacious, immersive soundstage.

This versatile driver excels in a variety of applications, from upgrading existing loudspeaker designs to building custom two-way or three-way systems. Its planar radiation pattern makes it particularly well-suited for use in open-baffle configurations, near-field monitoring setups, and high-end home theatre installations where precise imaging and airy treble are paramount. The driver's ability to maintain consistent off-axis response ensures that listeners enjoy detailed highs even when not seated directly in the sweet spot.

Technically, the PT6825-8 features an impedance of 8 ohms with a DC resistance of 6.4 ohms, making it compatible with a wide range of amplifiers. Its sensitivity of 92 dB SPL at 1 metre with 2.83V input ensures efficient operation, while the extremely low voice coil inductance of just 0.02 mH contributes to extended high-frequency response. The total Q factor of 2.06 indicates a well-damped character suitable for various enclosure designs. With a cut-out dimension of 175 mm by 66.3 mm and overall dimensions of 199.9 mm by 88.9 mm, this planar driver integrates neatly into custom baffles.

For audiophiles and DIY enthusiasts seeking transparent, detailed high-frequency performance with minimal coloration, the GRS PT6825-8 offers an exceptional balance of technical refinement and practical versatility.
