This ensures:
Powerful low frequency reinforcement
High output capability for larger spaces
Consistent performance at elevated levels
Compact Direct Radiator Design
Despite its high output capability, the Q118 maintains a relatively compact enclosure, making it suitable for both installed and portable systems. It utilises a direct radiator design combined with slot ports to improve efficiency and reduce turbulence.
This results in:
Efficient airflow and reduced port noise
Clean and controlled bass reproduction
Reliable performance across different environments
Flexible Deployment for Installation and Live Use
