explanation
A 4-way speaker system with a diaphragm made of high-polymer elements. woofer The cone
paper is made of carbon fiber mixed cone, and the surface is coated with a special acoustic
dumping agent. In addition, the frame that holds the diaphragm and magnet is made of strong
die-cast aluminum. The magnetic circuit is designed to suppress harmonic distortion components
with a long voice coil, a large magnet, and a copper cap on the center pole.
The squawker emphasizes directivity and uses a 10 cm cone type instead of a large diameter.
The diaphragm is a newly developed lightweight cone paper with increased rigidity. The magnetic
circuit uses a large magnet and an edgewise voice coil to greatly improve efficiency, and a copper
cap is used on the center pole to reduce distortion.
For the tweeter, die-cast aluminum is used for the frame to stabilize the characteristics, and an
epoxy adhesive is used to bond the voice coil assembly to the cone paper.
The super tweeter uses a unique piezoelectric speaker that uses a high-polymer element as
a diaphragm. This high polymer has many features such as light weight, good directivity because
the vibration system is fully driven, less exposure of characteristics due to resonance, and large
inputs.
The enclosure is a bass reflex type.
In addition, the network uses MP-type capacitors with low losses, and has a simple circuit type
that emphasizes phase characteristics.
