Detailed Information

While ported enclosures deliver important efficiency advantages over their sealed counterparts, they also present unique design challenges. In car audio, the desire for lower tuning frequencies from small enclosure volumes leads to long port lengths that often require compromising the port area. These compromises lead to higher airflow speeds through the port, which can create noise as the air is driven across the edge of the port. The flared port design minimizes these airflow effects by providing a smooth transition for the high-speed air flow, rather than an abrupt termination. The result is less noise and cleaner-sounding bass.
