HiVi RT1.3WE Isodynamic Tweeter

The HiVi RT1.3WE Isodynamic Planar Tweeter represents a sophisticated choice for audiophiles and custom speaker builders seeking exceptional high-frequency clarity. Engineered to deliver precise, detailed treble reproduction, this planar tweeter is ideal for upgrading existing loudspeakers or constructing new high-fidelity systems where low distortion and accurate sound staging are paramount. Its wide dispersion characteristics make it particularly suitable for both near-field monitoring and larger listening environments, ensuring a cohesive sound field.

Technically, the RT1.3WE employs an isodynamic driver with a rectangular diaphragm measuring 25.7 by 51.1 millimetres, which provides a large radiating surface for improved efficiency and reduced breakup modes. With a sensitivity of 92 dB SPL at 2.83 volts and a nominal impedance of 6 ohms, it integrates well with typical amplifier loads. The recommended crossover frequency is 2,500 Hz using a second-order filter, allowing seamless integration with midrange drivers. Its compact cut-out dimensions of 50.8 by 79.4 millimetres and a depth of only 20.8 millimetres facilitate straightforward mounting in a variety of enclosures. The RT1.3WE combines advanced planar technology with practical design, offering a refined solution for achieving transparent, airy high frequencies in serious audio projects.
