Does an EBP of 37 indicate a vented (ported) enclosure is preferred for a subwoofer?

An EBP (Efficiency Bandwidth Product) value of 37 indicates that a sealed enclosure is generally preferred for a subwoofer. Typically, an EBP value below 50 suggests that a sealed box is more suitable, while values above 60 often indicate a preference for vented or ported enclosures. This relationship stems from the balance between the driver’s efficiency and its response bandwidth.

A value of 37 signals that the subwoofer driver is better suited to achieving the desired low-frequency response within a sealed system. Sealed enclosures provide tighter bass response and can be beneficial for applications where precise sound reproduction is necessary.

While a vented enclosure can enhance efficiency and provide deeper bass at higher volumes for drivers with a higher EBP, it’s less suitable for drivers with a lower EBP like the one with a value of 37. The enclosure type influences performance characteristics such as transient response and overall sound quality. Thus, in the context of this question, the choice indicating that an EBP of 37 does not recommend a vented enclosure is correct.
