Things to Consider When Adding a Subwoofer

Key Specs to Consider When Adding a Subwoofer

Once you decide to add a subwoofer to your audio system, comparing specs can help you decide which subwoofer is best for your needs. Here are some key specs to look at:

  • Power – If you’re looking to really turn your car into a ‘boom car’, then you’ll need plenty of power. Pay attention to RMS power ratings, not peak or max power ratings.  RMS ratings measure continuous power handling and are a much more realistic measure than peak. Also, make sure you match the sub’s power handling to your amp’s power output.
  • Sensitivity – A sub that has a higher sensitivity rating requires less power to produce the same amount of sound as a sub with lower sensitivity. Typically subwoofers designed for sound quality (SQL) have a higher sensitivity rating, although this isn’t an absolute rule.
  • Frequency Range – This gives you an idea of how low a sub can play. The actual performance of the sub though can depend on lot of factors, such as the size, box type, etc. Also keep in mind that while humans can only hear sound down to 20 Hz, we can feel it even lower!
  • Enclosure – The type of enclosure you use will have a big effect on the type of sound the sub will produce. Typically, sealed boxes give you the most accurate sound, while ported enclosures produce more volume.
  • Voice Coils – Choose between single and double voice coils. Dual voice coil (DVC) subwoofers use two separate voice coils, each with its own connections, mounted on one cylinder, connected to a common core. DVC subs are a popular choice for those wanting more flexibility in wiring their sound systems.
  • Size – If your end goal is to have a system that plays loud and low (and space isn’t an issue), go for the biggest subs. Keep in mind though, that when properly powered and in the right enclosure, smaller subs can put out plenty of sound.
  • Impedance – Most subwoofers are rated at 4ohms impedance, but 2-ohm and 8-ohm are starting to be more common. When you’ve chosen a subwoofer, look for an amplifier that will match up to your sub in terms of power rating and impedance.
