RH3
3 Sound of Music Series is specially designed for professional sound reinforcement in
theatres, studios, multi-functional halls and for other indoors and medium & small sized
live event applications. Adopting the advanced computerized speaker designing and
stimulation technology, newly developed speaker material & optimized material configuration,
latest processing techniques, and combined with our experience in developing speakers,
Sound of Music Series aims at offering our users professional speakers with utmost
performance, high reliability and quality to cost ratio.
To bring natural and detailed full range sound with ideal fidelity to listeners is our target
for developing such a series. So unique magnetic circuit structure is used for improving
symmetry and precisely designed MF horn for effectively reducing distortion and enhancing
fidelity.
New generation high efficiency protection circuit is used for application in harsh
environment and also expanding the lifetime of the speakers.
Different clusters can be formed for a wide range of venues. The professional installation
system guarantees fast and correct installation.
The mid-high range wooden horn with a phase plug is specially designed for Sound of
Music series of speakers.
The special acoustic foam glued on the edge of horn can effectively control the edge
characteristic of the horn.
The tweeter adopts titanium diaphragm with high temperature heat treatment, round copper-
wrapped-with-aluminum voice coil and compression cavity with linear phase design. The
optimized high efficiency magnetic circuit configuration is used in all transducers for
lower distortion and better cooling due to excellent ventilation.
LF & MF section adopts long fibre paper cone of nonlinear thickness with specially coated
surround which has damping effect and high power sandwich type voice coil. The special
coating of the cone of MF component effectively reduces distortion and has solved the
sound quality problem usually existing in 2-way speakers.
Double woofer cabinet with big phase inverter ensures that there will be no LF attenuation
even with full power input, which can provide higher dynamic range. The acoustic sponge
behind the grille makes sound pure and clear by filtering the unneeded HF harmonic waves.
Separated woofer and mid-high cabinet design prevents acoustic colouration and achieves
more natural sound reinforcement for mid-high range. The speaker controller with DSP
and pre-processing program optimizes the system's performance.

HORIZONTAL DIRECTIVITY
The data of RH3 horizontal directivity were collected by testing the speaker system in a big anechoic
chamber. The distance between the testing microphone and the speaker system is 4 meters.
The scale is stepped by 6dB increment.
