RT8II Isodynamic Tweeter
The performance of intermediate frequency and
intermediate high frequency has pivotal status in sound
playback. For a good performance, engineers from many
countries have worked for many years; It results a period of
stir for a section of well performed system many times and
widely discussed; Its mental factor decided that ears are
sensitive for this section. Common ball top or cone
loudspeaker applied voice coil actuated indirectly vibration
performance, which easy produce various non-smoothes sound and
was restricted by physics features materials has difficult to
have well transient state and reply high sound pressure;
moreover different vocalization point make the influence of
point nature and phase become very important; The voice coil
of ribbon loudspeaker is manufactured directly on the surface
of film membrane can sync and equal actuate air. Quick
response reduce distortion and unequal frequency response, it
has features of accurate and clean sound and approach pure
resistance. In that, Swans put out ribbon intermediate tweeter
loudspeaker RT8II.
RT8II membrane applied ultra-thin
polyester materials, which voice and film membrane combine
together, the aluminum conduction part of voice coil takes
more than 90% and painted 3um anti-oxidized coating can
prevent the aluminum oxidation when sudden hot for aluminum
conduction wire. The vibration quality can be ignored compare
with traditional ball top tweeter, it is of 25mg, just as 1/5
of common tweeter, which means that any input transient state
messages can be made transient response. The driving systems
composed of 2 layers of neodymium iron boron magnet create a
push-pull actuation, which fill excellent absorb sound
materials at back of film membrane, increase damp at back of
film membrane, eliminate unnecessary vibration and reduce
distortion.
The panel of it applied new duralumin
alloy, the needs of sound radiation to design its shape, which
match with 2 row holes of front armor plate create equal and
wide response. There is no resonance in working frequency band
and impedance curve is a beeline, and its vocalization is on
plane are totally different with common point sound
resource.
Knowing all of the fantastic features of
RT1II, Comparing with common speakers, it will give you a
definite answer: it owns many advantages to offset the
shortcomings of traditional midrang, so it can be applied as
intermediate tweeter in many systems.
