The key element of
the RT2C-A is a membrane, which consists of KaptonŽ 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 wave guide,
controls the frequency response and directivity of the tweeter.
This tweeter has a larger 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 the aluminum conductors, dramatically
increasing the dynamic range of the RT2C-A.
The vibrating element of the RT2C-A is almost weightless in
comparison to a dome tweeter. It provides an immediate and precise
response to any transients in original signal.
RT2C-A has a resistive impedance in the audio frequency range.
This unique feature makes the RT2C-A a friendly load for an
amplifier and substantially facilitates easy crossover design.
Unlike other drivers, the RT2C-A has an essentially linear phase
response that provides time coherent reproduction resulting in
accurate musical rhythm and imaging.
Unlike other conventional tweeters, the RT2C-A has well controlled
sound dispersion in the 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 the desired vertical
directivity!
Considering all properties of RT2C-A, it becomes clear why many
critical listeners among audiophiles very highly prize planar
transducers for their unsurpassed clarity, transparency and
ability to deliver every tiniest musical detail.
Since the RT2C-A has exceptional sonic resolution and ability to
reveal the dynamics of instruments, it is recommended to match it
with drivers having similar properties in order to maximize
overall integrity of a speaker system.
Recommended second-order crossover cut-off frequency - from 1.8
kHz. |
