This is a tall boy speaker system from the Bolero series.

It is equipped with a 12.5 cm cone woofer in the low range and a 12.5 cm cone scoker in the middle range.
These units use a double voice coil system. The voice coil bobbin is made of Nomex bobbin with excellent heat resistance, and the diaphragm is made of Neoflex, which is lightweight, rigid and has moderate internal loss.

A 3.0 cm inverted dome type tweeter is installed in the high range.
The vibration plate of this unit is made of titanium alloy and coated with special paint to solve the problem of sound quality of titanium alloy which tends to be sharp in general.

The internal resistance of the network is reduced by simplifying the circuit and using carefully selected parts.
