HiVi RT2H-A Isodynamic Planar Horn Tweeter

The key feature of the RT2C-A and the RT2H-A is the membrane, which consists of Kapton film with a pattern of aluminum conductors. The conductors cover about 90% of the whole vibrating area.

.

Highlights

• Nearly weightless Kapton diaphragm for incredible transient response
• Semi-horn loaded faceplate for improved efficiency
• Large diaphragm can accommodate crossovers as low as 3,000 Hz

Product details

Why Isodynamic? Contrary to a conventional dynamic driver, these transducers have a driving force distributed evenly over the whole area of their vibrating elements. The key feature of the RT2C-A and the RT2H-A is the membrane, which consists of Kapton film with a pattern of aluminum conductors.

The conductors cover about 90% of the whole vibrating area. The membrane assembly is placed precisely between two rows of Neodymium and Barium Ferrite bar magnets. A larger membrane area provides higher power handling and substantially extended low-end cut-off frequency. The aluminum mounting flange, with flared waveguide, controls the frequency response and directivity of the tweeter.

These tweeters are magnetically shielded and are extremely flat with a depth only 27mm including the mounting flange.
