The 3 way speaker system which combined the gathered
edge which is a Lo-D loudspeaker technology, and the metal veneer cone
L-253 of a 25cm metal veneer cone Woofer is carried in low-pass.
The
low-pass play excellent in combining the gathered edge of a Lo-D original
technology with the metal cone which carried out the about 1 octave (twice)
expansion of the waveguide-plunger oscillating band of a loudspeaker in the
orientation of a high region with the metal cone is realized. .
M-65 of
a 6.5cm metal cone squawker is carried in the mid range.
H-40 of the 4cm
cone type tweeter by the metal veneer is carried in the high region.
Being
conscious of relation of sound, the same form as a mid range and low-pass is
adopted.
The level control is carried in a mid range and quantity
regions.
