In general, front ported monitors don’t suffer if you need to position them close to a wall or corner
In some cases from different manufacturers, monitors that are rear-ported can have their frequency responses change if they are too close to a wall.
The G4 line has a new proprietary front-firing port that systematically manages the airflow in a way that makes it conducive to virtually any configuration.
This system starts from the inside of the monitor itself and continues through the port and speakers.
