Speakon Outputs
The upper Speakon jack has both Channel 1 and
Channel 2 outputs, so it is especially useful for parallel,
bi-amp, or BRIDGE mono operation. The other Speakon
carries only Channel 2's output. See the illustrations at
above.

Source (INPUT) comes from the output source of the
active/powered speaker while the bridge (OUTPUT)
connects to the passive/non-powered speaker.
A speakon cable is required to connect the “OUTPUT”
of the acive/powered speaker to the “INPUT” of the
passive/non--powered speaker. Please order the speakon
cable from our authorized dealers.
NOTE
Dynamic Fusion Technology™ (DFT)
The Better Music Builder engineers have been working hard on
bringing home entertainment to the next level - the experience
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 using the latest technologies. For this reason, Better
Music Builder developed the Dynamic Fusion Technology™.
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 impedance at high frequencies, provid-
ing extended treble output, reduced harmonic distortion, and a
reduction in the inductance modulation that typically accompa-
nies 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
pole piece) being the other. The pole piece and back plate
are often a single piece, called the pole plate or yoke.
DFT’s Dynamic Transition Waveguides™ (DTWaveguides)
represents the latest horn technology. In addition to providing
smooth, low distortion sound, DTWaveguides delivers uniform
off-axis frequency response to every point within the intended
coverage area – not just in the horizontal and vertical planes –
resulting in superior array – ability of multiple loudspeaker
systems. PTWaveguides combine outstanding pattern control
with undistorted sound for natural music and intelligible speech.
