Hi Robert,

The turbocharger is an alternative to plugging one port for maximum deep bass extension. Basically it allows one to lower the port tuning without sacrificing port cross-sectional area. This unit is no longer available, but I wouldn't worry too much about it, as the subwoofer is still quite strong without it.
