- Sealed Subwoofers: Sealed subwoofers provide more tight and accurate bass but require more power for the same volume level compared to ported models. Thus, larger sealed subwoofers may be necessary for optimal performance.
Power and Efficiency
In addition to size, the amplifier wattage of your subwoofer affects its performance. A subwoofer with a high power rating will need to be compatible with the amplifier in your audio system. A mismatch can lead to distorted sound or damage to the subwoofer.
1. Understanding Wattage Ratings
When evaluating subwoofers, you’ll find specifications for both RMS Wattage and Peak Wattage:
- RMS (Root Mean Square) Wattage: This rating indicates the continuous power output and is a better measure of a subwoofer’s reliability.
- Peak Wattage: The maximum amount of power a subwoofer can handle for short bursts. This figure tends to be inflated for marketing purposes.
2. Efficiency Ratings
Subwoofer efficiency is often expressed in dB (decibels). An efficient subwoofer requires less power to achieve the same output, making it a smart choice for users with limited power supply.
Tips for Selecting the Right Subwoofer Size
- Assess Your Space: Measure your room and determine how loud you want your audio to be. This will help you choose the right subwoofer size.
- Listen Before You Buy: Whenever possible, test several models to hear how they perform. Bass can sound drastically different depending on the setup.
- Consider Multiple Subwoofers: In large rooms, two or more smaller subwoofers can sometimes be more effective than one large subwoofer, providing balanced sound throughout the space.
