The large-sized floor type speaker system developed
as a flag ship model which supplies the technology of Ti series and represents
the thought and the technology of a JBL loudspeaker
It calculated to the
wide band thoroughly to the location of coexistence of flat frequency
characteristic and power response, the phase matching of each unit, the
diffraction effect of an enclosure, and a backplane duct, and the form is
determined as it.
LE14H-1 which is 38cmSFG Woofer by the Aqua positive
compound cone is adopted as low-pass.
20cm cone type 118H developed for
250Ti is adopted as inside low-pass.
104H of a 13cm special
polypropylene cone unit is carried in the mid-high range.
The special filler strip is raising the synthetic for polypropylene to
the base sharply. And the same internal loss as polypropylene is maintained.
044Ti tweeter which used the pure titanium diaphragm is carried in the high
The original technology of spraying the fault style of high-voltage
nitrogen gas has realized dome molding of 25-micron thickness, and the response
which was excellent in the origami work of Japan combining the diamond edge
pattern and reinforcement rib which obtained the Tips is gained.
strapping busbar scheme with little tone-quality failure is adopted as an
The round baffle is used for an enclosure in consideration
of the influence by the diffraction effect, and high-density particle board is
used for the material. Moreover, surface finish is natural teak finish.
Furthermore, in order to prevent disorder of the response by reflection with
a grill frame, the flooring grill using an original floating structure is
