GRS PT5010-8 Planar Mid/Tweeter

The GRS PT5010-8 Planar Mid/Tweeter represents a significant step forward in high-frequency audio reproduction, offering a refined solution for those who demand clarity and precision from their sound systems. This planar magnetic driver is engineered to deliver exceptionally clear and detailed high-frequency performance, making it an ideal choice for audiophiles, home theatre enthusiasts, and professional audio designers seeking to upgrade or build custom loudspeakers. Its low distortion characteristics and wide dispersion pattern ensure that every nuance of the recording is faithfully reproduced, whether used as a dedicated tweeter in a multi-way system or as a full-range mid/tweeter in more compact designs.

Technically, the PT5010-8 is built around a planar magnetic radiating element, which inherently offers lower distortion compared to conventional dome tweeters. With an impedance of 8 ohms and a sensitivity of 94 dB (measured at 1 metre with 2.83V), it integrates efficiently into a variety of amplifier configurations. The extremely low voice coil inductance of just 0.01 mH contributes to extended high-frequency response and excellent transient behaviour. The mechanical Q (Qms) of 2.14 and total Q (Qts) of 1.96 indicate a well-damped driver suitable for sealed or open-baffle applications. The DC resistance measures 6.8 ohms. For installation, the cut-out size is 229.9 mm by 106.7 mm, with overall dimensions of 255 mm by 125 mm, allowing for flexible placement in bespoke enclosures. The GRS PT5010-8 is a superb choice for achieving detailed, airy high frequencies with minimal coloration.
