Improved Low-Frequency Extension and Output: Compared with sealed enclosure designs, the ported structure leverages resonance between internal cabinet air and the port tube to effectively extend low-frequency response, pushing the -3dB point (F3) down to approximately 60Hz for richer, more relaxed low-frequency energy.

Preserved Advantages of Coaxial Point Source: Retaining the coincident acoustic centre characteristic of coaxial drivers, it delivers excellent off-axis frequency response and effectively mitigates phase interference and comb filtering during close-range or off-angle listening.
