How to Choose
When selecting an 18-inch subwoofer, consider your specific needs: power handling capacity, enclosure type, and application. RMS power rating indicates how much continuous power the sub can handle without damage, so match this with your amplifier’s output. Additionally, look at the voice coil configuration—dual voice coils offer wiring flexibility, while single coils tend to be simpler. The enclosure type—sealed or ported—affects the sound: sealed enclosures provide tighter bass, while ported designs deliver louder, more boomy lows. Finally, pay attention to build quality and cooling features, especially if you plan to push the subwoofer to its limits over extended periods.
