Lo-D HS-500

Commentary

This 2-way speaker system is famous as a representative work of Lordi.

The low range is equipped with L-200 which is a 20 cm cone type woofer.
This unit is equipped with a ギャザードエッジ and a centering spider to support the vibration system. The centering spider is sufficiently aged and molded to support the effective mass of the vibration system, so that the secular change is suppressed.
In addition, a long travel short voice coil is used to avoid uneven magnetic flux distribution, which causes distortion. Only uniform magnetic flux distribution is used. This voice coil has an aperture of 10 mm and is simple ± 6 mm.

The H-70HD horn type tweeter is mounted in the high range.
This horn is carefully shaved one by one from the aluminum round bar. It is equipped with an acoustic lens on the front to improve directional characteristics. In addition, high-purity Mylar is used for the diaphragm in order to be light and durable to high temperature and humidity.

The network section uses a 12dB/oct LC network. In addition, it is equipped with a 2 dB step Attenuator so that it can be adjusted according to usage conditions.
Multi-amplifier terminal is also mounted.

The dumped bassreflex system is used for the enclosure to obtain the advantages of both the enclosed system and the bass reflex system.
In this system, the port and enclosure are filled with glass wool five times the air density to provide an appropriate acoustic resistance to enhance the bass reproduction capability. In addition, in the dumped bassreflex system, since sound is emitted from both the port and the speaker, the vibration amplitude of the speaker is smaller than that of the enclosed type, which reduces distortion at the bass.
It is made of hard homogen Holtz and has a 4-side finish.
