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
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
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.
