INTRODUCTION
Better Music Builder engineering team created a high
performance speaker product called the Dynamic Fusion
Series (DFS-206, DFS-306, DFS-912, DFS-915, DFS-112 SUB
and DFS-118 SUB) by using the Dynamic Fusion Technology™
(DFT).
Dynamic Fusion Series are high performance speaker which
developed with the latest computer stimulation design
technology and manufacturing technology. With our high
efficient professional speakers with unique LF extension
technology, it performs high quality, precise clarity and
reliability. LF unit manufactures with non-linear fabric paper
cone which provides waterproof feature. HF unit manufactures
with high temperature treated magnalium diaphragm, voice
coil with copper cladding aluminum wire and compression
cavity designed with linear phase technology. Magnetic
circuit of tweeter generates high magnetic energy, low
distortion and excellent ventilation function and high strength
plywood absorb the sympathy of noise for higher perfor-
mance.
The 2-Way High Frequency Speaker (DFS-206 & DFS-306)
has three transducers 2-way phase-reversed full range
professional speaker, professional and efficient transducers,
computer simulating design.
The compact design of High Definition Speaker (DFS-912 &
DFS-915) can be easily pole-mounted or permanently installed
onto wall, ceiling or under balcony. The engineering team of
Better Music Builder designed this speaker specifically for all
kinds of rock bar, entertainment bar, night club, and all kinds
of living performance and portability. The Bass Powered
Speaker designed by the engineering team of Better Music
Builder specifically suit the needs for all kinds of medium-sized
conference room, multi-function hall, church and general small
performance site, and also for home use.
Each cabinet of Bass Powered Subwoofer (DFS-112 SUB &
DFS-118 SUB) is made of with solid plywood with advanced
environmental protection polyurethane-based painting which
is very dense. We are fencing each cabinet to provide strong
ultra-weather ability. With this design, each bass speaker
reduces interference and enhances the sound quality.
The single angle pole mount offers much more control than
the typical angle mount. With a 10 degree down angle, the
speaker can be directed down toward your audience,
keeping the energy off the back wall enhancing coverage
and clarity.
They all are sold individually to tailor-made your system need.

Intro
Dynamic Fusion Technology™ (DFT)
The Better Music Builder engineers have been working hard
on brining home entertainment to the next level, the experi-
ence that people have been dreaming about but never had
before such as real excitement, freestyle performing, and
intensive hearing are included all in one system. To meet
audience’s expectation, our engineers understand the need to
research and develop the latest technologies. For this reason,
Better Music Builder step developed the Dynamic Fusion
Technology™ (DFT).
DFT practices the latest computer stimulation technology to
design smaller size circuit with better distortion minimization
function. The T share horn is specially designed to facilitate
the composition of array. The woofer uses a 75mm diameter
high-power voice coil with round copper wire, and the layer
is 2 way around the inside and outside. The voice coil frame
material with very high levels of TIL provides excellent strength
and high power capacity, which can boost the speaker
power up to 400W, and the short-term maximum power can
reach up to 1600W. The tweeter with magnalium
diaphragm is made by high-temperature heat treatment
process to maximize damping strength and to reduce
proportion of 3rd harmonic distortion to create more natural,
delicate and nice sound.
DFT is a unique design that integrates in the drivers to
enhance several critical performance parameters: frequency
response, power output, and distortion.
By implementing DFT, engineers understand that the shape of
the pole piece that can affect the magnetic interaction
between the voice coil and the magnetic field, and is
sometimes used to modify a driver’s behavior. A “shorting
ring”, or Faraday loop, may be included as a thin copper
cap fitted over the pole tip or as a heavy ring situated within
the magnet-pole cavity. The benefits are to reduce imped-
ance at high frequencies, providing extended treble output,
reduced harmonic distortion, and a reduction in the induc-
tance modulation that typically accompanies large voice coil
excursions. On the other hand, the copper cap requires a
wider voice-coil gap, with increased magnetic reluctance;
this reduces available flux, requiring a slightly larger magnet
for equivalent performance.
The wire in the voice coil is made of copper, and its cross
section is hexagonal, giving varying amounts of wire volume
coverage in the magnetic gap space. The coil is oriented
co-axially inside the gap; it moves back and forth within a
small circular volume (a hole, slot, or groove) in the magnetic
structure. The gap establishes a concentrated magnetic field
between the two poles of a permanent magnet; the outside
of the gap being one pole, and the center post (called the
