Features to Consider When Buying a 15-inch Subwoofer

Before diving into our top picks, it’s important to understand the key features that make a great subwoofer. Here are some factors to consider when choosing your new 15-inch subwoofer:

Power Handling

A subwoofer’s power handling determines how much power it can handle without getting damaged. Look for RMS power ratings, as they provide a more accurate representation of the subwoofer’s continuous power handling capabilities.


Sensitivity refers to how efficiently a subwoofer converts power into sound. A higher sensitivity rating means that the subwoofer will produce more sound with less power.

Voice Coils

Voice coils come in single, dual, and quad configurations. Dual and quad voice coil subwoofers offer more flexibility when it comes to wiring and impedance options.

Enclosure Type

Subwoofers can be mounted in sealed or ported enclosures. Sealed enclosures provide tighter, more accurate bass, while ported enclosures produce louder, more aggressive bass.
