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 two 38 cm cone type Woofers 2226H for low range.
The Neutrik Speakon connector is used for the connector.
