RT2E-A Features

Why we call RT2E-A isodynamic?

Contrary to a conventional dynamic driver, this transducer has a driving force distributed evenly over the whole area of vibrating element.

What is special in RT2E-A?

The key element of RT2E-A is a membrane, which consists of a Kapton film with a pattern of Aluminum conductors. The conductors take about 90% of the whole vibrating area. The membrane assembly is placed precisely between two rows of Neodymium and Barium Ferrite bar magnets. The Aluminum mounting flange with flared waveguide controls the frequency response and directivity of the tweeter.

This tweeter has large membrane area providing higher power handling and substantially extended low end cut-off frequency.

The clamped membrane area is connected to the massive front metal plate. This combined with a special heat conductive compound provide effective cooling of aluminum conductors, dramatically increasing dynamic range of RT2E-A.

The vibrating element of RT2E-A is almost weightless in comparison to a dome tweeter. It provides an immediate and precise response to any transients in original signal.

RT2E-A has resistive impedance in audio frequency range. This unique feature makes RT2E-A an easy load for an amplifier and substantially facilitates a crossover design.

Unlike other drivers, RT2E-A has essentially a linear phase response that provides time coherent reproduction resulting in accurate musical rhythm and imaging.

Unlike other conventional tweeters, RT2E-A has well controlled sound dispersion in vertical plane. This feature helps to avoid disturbing floor and ceiling reflections in a home environment thus enhancing clarity and imaging accuracy. Remarkably, you don't have to use three tweeters in home theater systems anymore in order to achieve desired vertical directivity!

Considering all properties of RT2E-A, it becomes clear why many critical listeners among audiophiles prize very high planar transducers for their unsurpassed clarity, transparency and ability to deliver every tiniest musical detail.

Since RT2E-A has exceptional sonic resolution and ability to reveal the dynamics of instruments, it is recommended to match it with drivers having the similar properties in order to maximize overall integrity of a speaker system.

Recommended second order crossover cut-off frequency - from 1.8 kHz.
