The specially designed 18" component, combined with the double bass reflex tuning box, provides excellent results, high sensitivity and low thermal compression. The exhaust duct has a good profile, which is more conducive to the flow of airflow and reduces turbulence noise, even at a very high sound pressure operating level, these combined characteristics help to ensure the sound quality of SW18 in terms of accuracy and musicality.
The performance of the SW18 cabinet depends on the preset selection and the physical configuration of the system. The cabinet is made of high-grade birch plywood.

SW18 is specially designed for line array loudspeakers, which can extend the minimum operating frequency of the companion system to 32Hz. The compact and integrated assembly makes it well coupled with the AR08 rigging configuration.
