Descrizione del prodotto HiVi Swan RT2C-A Isodynamic Tweeter Planare

The key feature of the RT2C-A is the membrane, which consists of Kapton film with a pattern of aluminum conductors, with transducers that have a driving force distributed evenly over the whole area of their vibrating elements.

Highlights

Near weightless diaphragm results in exceptional transient response
Extremely flat frequency response from 2,000 to over 20,000 Hz
Remarkably linear impedance and phase simplifies crossover design
Reproduces the tiniest details with extreme clarity and transparency

Product details

HiVi RT2C-A Planar Isodynamic Tweeter

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 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. This tweeter is magnetically shielded and is extremely flat with a depth only 27 mm including the mounting flange.

The RT2C-A has resistive impedance in the audio frequency range. This unique feature provides a friendly load for any amplifier and facilitates easy crossover design. Unlike other drivers, it has an essentially linear phase response that provides time coherent reproduction resulting in accurate musical rhythm and imaging. The vibrating elements are almost weightless compared to that of a dome tweeter. As a result, it provides an immediate and precise response to any transients in the original signal. The RT2C-A has the exceptional ability to reveal the dynamics of instruments with complex high frequency spectra. Unlike conventional tweeters and electrostatic speakers, this tweeter has an extremely wide sound dispersion in the horizontal plane. At the same time, contrary to other dynamic tweeters, it also has well-controlled dispersion in the vertical plane. This feature helps to avoid disturbing floor and ceiling reflections, increasing imaging accuracy. There is no need to manipulate the network or use multiple units to achieve the restricted vertical directivity necessary for home theatre applications.

When considering all of the properties of the RT2C-A, it becomes clear why many critical listeners among audiophiles highly prize planar transducers for their unsurpassed clarity, transparency and the ability to deliver every tiniest musical detail. Since these isodynamic tweeters have the exceptional ability to reveal the dynamics of instruments and sonic resolution, it is recommended to match it with drivers having similar properties in order to maximize the overall integrity of a speaker system.

The clamped membrane of the RT2C-A is connected to the more massive round front metal plate. This, combined with a special heat conductive compound, provides effective cooling of the aluminum conductors, dramatically increasing its dynamic range. Recommended crossover frequency is >1,700 Hz.

I have recently used this TW to replace SB Audience Rosso compression driver (with triple price) and results are stunning… all details remains there as well as dynamic, but sound much smoother, bigger, wider a deeper soundstage and overall more balanced tonality. This is a bargain for it price.
