GRS PT2522-4 Planar Tweeter

The GRS PT2522-4 Planar Tweeter offers a refined approach to high-frequency reproduction, delivering exceptional clarity and detail that elevates any audio system. Engineered for audiophiles and DIY enthusiasts alike, this planar tweeter is an excellent choice for upgrading existing speaker designs or constructing bespoke loudspeakers from scratch. Its precise, airy sound makes it particularly suited to home hi-fi setups, studio monitors, and custom multi-way speaker projects where accurate treble response is paramount.

At the heart of this tweeter lies a planar radiating element, which provides low distortion and a wide, even dispersion pattern compared to conventional dome tweeters. With a sensitivity of 93 dB SPL at 1 metre (2.83V), it integrates efficiently into most systems, while its 4 ohm impedance ensures compatibility with a broad range of amplifiers. The extremely low voice coil inductance of just 0.01 mH contributes to extended high-frequency response and minimal phase shift. Mechanical and total Q factors of 4.6 and 4.46 respectively indicate a well-damped, controlled performance. The compact dimensions—88.9 mm by 67.6 mm overall, with a cut-out of 72.9 mm by 58.4 mm—allow for straightforward installation in enclosures or baffles. A DC resistance of 3.4 ohms completes the technical picture, ensuring reliable operation.

Whether you are refining a cherished pair of speakers or embarking on a new build, the GRS PT2522-4 delivers the transparency and precision required for truly immersive listening.
