There are different
views about which make a good effect in midrange playback between
ball top and cone loudspeaker in professional speaker field. The
people who like cone midrange thinks that it can choose lower
divided frequency point for cone midrange, i.e. 200Hz-250Hz, but
the lowest divided frequency point of ball top midrange is
approximately 3-4 time higher than cone midrange. When produce
loudspeaker system and crossover, we will consider every aspects
accurately in common sense, it is impossible for a 500mm ball top
midrange match with a 12-inch bass loudspeaker. In ordinary, you
can achieve much bigger radiation space than cone midrange by
using ball top midrange units and more clear sound.
Because we agree with the above information about ball top
midrange and ensure its value of Hi-end sound, let me introduce
DMN-A as follows: It applied Germany manual manufactured ball top
film membrane and circumgyrate and symmetrical fits, i.e. voice
coil, high power 50mm aluminum framework, conduction lines
surrounded double deck rectangle section, and 180 degree symmetry
soft down-lead. The whole vibration fits are ultra-light and
durable even under high power battery. DMN-A's magnet circuit also
applied "motor" structure, double neodymium iron boron
alnico "sandwich" style design apply linear actuation
and effective radiator for suspended voice coil, which can get low
resonance wave distortion and very big power handling. The back
magnet circuit of DMN-A prototype design has apertures in favor of
lose heat for "motor" structure. Moreover, it applied
linear non-resonance crust. Resonance leading style back cavity
design can reduce the distortion of low frequency. It has
miniature size convenient to use. High radiated open style bracket
further strengthen the unit power handling.
Frequency response curve of DMN-A curve is very smooth, from 800
to 8000Hz is of negative 1.5dB asymmetry level. When departure
axis 30 degree, it reduce 3dB at 5.5kHz, but the curve and axis
direction are adjacent. The average sound pressure sensitivity of
DMN is 91dB, and it can apply 108.8 dB SPL pulse sound pressure
output, which are fully enough for broadcasting, even can work
under profession control monitor system.
Because it has a unbelievable smooth frequency response, DMN-A is
extremely easy match with any units, such as, Swans R1 Ribbon
Tweeter and SD1.1 Ball Top Tweeter with 800Hz-8kHz useful
operating frequency scope. It worth mention is that you can apply
this unit without crust; just put it into a no more than 1.5L
sealed room. So, you can design into on wall style flat
loudspeaker system, and it also can send out high-quality sound.
This light and miniature midrange unit can be arranged at
supplementary speaker unit position nearly, those permit more
exquisite outward design. |
