Based on the technical essence of S-180D, this is a speaker system that is compact and has a magnetic shielding design.
A 22 cm cone type woofer using a unique EBD (Electronic Bass Drive) system is installed in the low range.
The EBD method uses a double voice coil structure to electrically expand the low frequency range, and the magnetic circuit uses the Linear Drive Magnetic Circuit (LDMC) method to increase the linearity of the driving force by amplitude, thereby greatly reducing the amplitude distortion factor.
DRS (Dynamic Response Suspension) is adopted for the vibration support system, and high response from minute input to large input is obtained.
The magnetic circuit of this woofer uses a dual magnet magnetic shield system that incorporates another magnet and a cap to reduce leakage flux.
The mid-range is equipped with a 6.6 cm cone type mid-range.
This unit uses a one piece boron alloy diaphragm that was born from repeated computer simulations and is driven by a φ 35 mm voice coil.
A beryllium ribbon type tweeter with a direct drive structure is installed in the high range.
The S-1300DV uses a new horn to increase energy near the crossover and improve directivity.
The mid-range and tweeter units are covered with magnetic shielding caps to reduce leakage flux.
Round baffle is used for the enclosure and R is provided at the corner to reduce diffraction phenomenon.
There was a model with black finish other than wood grain finish.
