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. |
