Factors to Consider When Choosing the Best Powered Subwoofers

1. Active or Passive Subwoofers

A powered or active subwoofer is one designed to be self-contained, with line-level inputs and outputs. This unit will also have an amplifier and volume control panel.

On the other hand, a passive subwoofer requires an external amplifier in the same way that a loudspeaker does. These subwoofers reduce low-frequency sounds using the power, which means that the receiver needs to be strong enough to handle the bass output. If not, the subwoofer will drain the power from your amplifier.

2. Sealed vs. Ported Subwoofers

The best-powered subwoofer will either have a sealed or ported enclosure. The sealed types, also called acoustic suspension, don't allow air to move through them. As a result, they can deliver a quick and responsive bass that sounds tight.

The ported boxes, also known as bass reflex enclosures, feature an integrated air vent for reinforcing the low bass output. So, if you are looking for an option that uses minimal power while providing maximum output, these are the units for you. Unfortunately, these subwoofers are much larger than the sealed box types.

3. Wired or Wireless Subwoofers

Subwoofers can come wired or wireless. The exact choice will depend on your preferences since either can work well. Nevertheless, if you want a fine-tune output without compromising the output quality, you should go with wired subwoofers.

The primary advantage wireless units provide is unrestricted movement and freedom from tangling cables. Unfortunately, these subwoofers will have a range within which they can work optimally, but the sound won't be as clear if you exceed this limit. This is because wireless connections are less stable than wired ones in delivering sound.

4. Down Firing vs. Front Firing

The next thing to consider is the direction in which the sound will go. Down firing subwoofers are the ones that direct sound towards the floor. This makes them a great choice if you plan to place them a distance from the main speakers or in the corners of your room.

On the other hand, front-firing subwoofers direct sound either in front or on the sides, which makes them great for sitting under your TV. The only difference between the down-firing and front-firing units is their placement inside your room.

5. Size

The size of the models is also crucial to consider since you don't want to rearrange your entire room to accommodate your new subwoofer. The ideal unit features a compact and sleek design that allows you to set it up almost anywhere in your space without taking up too much space.

If you have unlimited space, you can take a large or bulky unit since you don't need to reserve any room. Nevertheless, going for small models will help you conserve space while meeting your listening needs appropriately. As such, you should take note of the number of inches comprising the build of the subwoofer to ensure it can fit in your home.

6. Price Range

The price of the unit you select is another crucial factor. The most expensive models aren't always the most suitable option since there are some low-priced subwoofers that can meet your requirements without draining your pockets. However, high-end units will come with features that can add convenience to users in contrast to the simple use of the low-priced subs.

The priciest options won't always give the best sound output. So, you'll want to look for the one that comes at a convenient price range.

7. Power

When looking at power, you'll also need to consider the driver size. Most people assume that the amount of power of the subwoofer directly translates to how loud it gets. However, this isn't true since the volume controls determine the loudness of the sound you hear.

The more powerful the model, the less vibration and distortion it will deliver as you use it to listen to music. If your budget allows you to take models that use more than 400 watts, there's no reason to settle for less.

8. Number of Subs

While you might have planned for just one subwoofer, you can go with more than one if you can afford to. This is because your home theater system could accommodate several subwoofers without compromising on performance. As a result, if you have a large indoor space, you can go with several subs rather than just one.

Fortunately, the best-powered subwoofer for your room could involve several subs supporting your audio system for an immersive listening experience. However, if you don't need that much sound, you don't need more than one sub since it could be loud enough for you.

9. Volume and Equalization Controls

The last factor to keep in mind is whether you can adjust the various sounds the subwoofer is producing. Since subwoofers are meant to amplify sound to high levels, they could deliver an output that doesn't sound good depending on the music or movie you enjoy. That's why you should look for units with a control panel allowing you to adjust the bass and treble sound for a customized listening time.

These controls can help you manage the sound output so that you listen to your playlist or watch your movies the way you prefer to. Otherwise, you could end up listening to a subwoofer that distorts sound when you try to increase the volume.
