The vibrating element of a planer tweeter is almost weightless in comparison to a dome tweeter. It provides an immediate and precise response to any transients in the original signal.
HiVi RT1C-A Planar Isodynamic Tweeter
The vibrating element of a planer tweeter is almost weightless in comparison to a dome tweeter. The element consists of Kapton film with a pattern of aluminum conductors which is placed precisely between two Neodymium bar magnets. It provides an immediate and precise response to any transients in the original signal. These drivers are magnetically shielded and feature a linear phase response which provides time coherent reproduction resulting in accurate musical rhythm and imaging. Unlike other conventional tweeters and electrostatic speakers, the RT1C and RT2a have an extremely wide sound dispersion in the horizontal plane. At the same time, they have a well controlled sound dispersion in the vertical plane. This helps to avoid disturbing floor and ceiling reflections in a home environment thus enhancing clarity and imaging accuracy. The RT1C features a radiating area of 50 x 13mm and a round cast aluminum face plate. Although designed to be used with either the F5 or F6 bass/midrange drivers in a small 2-way system, it is also well suited for 3-way applications. Recommended second order crossover cut-off frequency - from 3kHz.
