Commentary
A sub-base system of the sound power series.
When a sub-base system is added to a full-range system, a power handling margin on the full-range side is created by assigning a low-frequency region with a large energy to the sub-base, and the allowable input of the entire system can be increased.
It is most suitable for low-frequency reinforcement in spaces requiring high sound pressure, such as discos and clubs, or in places with limited settings.
The unit is equipped with 2 30 cm cone type Woofer 2206H for low range.
The Neutrik Speakon connector is used for the connector.
