Things To Remember While Buying An Under-Seat Subwoofer

There are a few important to be kept in mind while buying your preferred subwoofer. Having these preferences set makes it easier to choose your ideal under-seat subwoofer.

To get a heavy bass, your subwoofer needs to be provided with a lot of energy. This extra energy can only be handled if your subwoofer has a higher RMS and peak power rating. Go for a subwoofer that has a higher rating but you need to make sure that the rating matches that of your amplifier or other units in your system.

Sensitivity is as important as power. A higher sensitivity rating means that the subwoofer will require less power to work. The type of enclosure also makes a difference in how the subwoofer functions. 

The frequency range will tell you a lot about how low your subwoofer can play. This will tell you how rich and deep of bass you will get with your subwoofer. A subwoofer will contain either a dual voice coil or a single voice coil.

Since you are buying an under-seat subwoofer, size is extremely important. To get more powerful performance, you will have to go for a bigger subwoofer. This may cause space issues as they might not fit under your seat as well as you would want them to.
