Types of Home Theater Amplifier Subwoofers

A home theater subwoofer amp connects to the home theater system to amplify the sound output. The home theater amplifier subwoofer comes in different types, which include the active subwoofer and the passive subwoofer.

An active subwoofer is self-powered, meaning it has a built-in amplifier. It also has an enclosure and a subwoofer driver. The active subwoofer is very easy to install and doesn't require extra amplification. It is also the most common type of subwoofer found in home theater systems. Because it is self-powered, the active subwoofer is more popular among people who need to connect a subwoofer to a receiver with no subwoofer output. Additionally, the active subwoofer is a better choice for those who don't want to buy a separate amplifier or use an AV receiver.

A passive subwoofer, on the other hand, relies on an external amplifier for power. The passive subwoofer doesn't have a built-in amplifier. It only comprises the subwoofer driver and an enclosure. The passive subwoofer is ideal for people with limited space. It is also a good choice for those who want to customize their home audio system. However, the passive subwoofer has some disadvantages. It requires more space because it needs a separate amplifier. Also, the passive subwoofer is more complicated to set up compared to the active subwoofer. To use a passive subwoofer, a buyer needs to connect the home theater system through an AV receiver, stereo receiver, or power amp.

Another type of subwoofer amplifier home cinema is the in-wall subwoofer, which is installed inside the wall for a clean, space-saving appearance. Like the in-wall subwoofer, the in-ceiling subwoofer is mounted inside the ceiling and is ideal for a discreet audio setup.

Functions and Features

• Power Output:

The power output of a home theater amplifier will vary depending on the model and brand. Normally, it will range from 150 watts to 1000 watts or even more. For business buyers, it is important to stock subwoofer amplifiers with different power outputs. This allows them to cater to the varied needs of the customers. High-power amplifiers are ideal for large rooms, while the low-power ones are perfect for small spaces. It is also important for buyers to know the power output of the subwoofer amplifier before purchasing it. This information is often listed on the product specifications. It should be noted that the power output of a subwoofer amplifier affects the sound quality and volume level. Amplifiers with high output power produce a louder sound than those with low output power. But, the sound quality may be affected if the amplifier is pushed to the maximum volume.

• Number of Channels:

Another important feature to consider is the number of channels. Most 2.1 home theater systems have two channels; one for the left speaker and the other for the right speaker. There is also one channel for the subwoofer. Some subwoofer amps may have more than two channels. For instance, a 5.1 channel has five channels for the speakers and one channel for the subwoofer. There are also 7.1 channel amps with seven channels for the speakers and one channel for the subwoofer. Subwoofer amplifiers with more channels have a better surround sound system. The audio is distributed evenly, making the watching or listening experience more enjoyable.

• Input and Output Options:

Apart from the features mentioned above, a home theater sub amp with Bluetooth may have different input and output options. The common input options are Bluetooth, Wi-Fi, RCA, XLR, and HDMI. The common output options are HDMI, Bluetooth, and RCA.

• Size:

Apart from the features mentioned above, a house subwoofer amplifier comes in different sizes. The size of the subwoofer will depend on the type and brand. It can be large, medium, compact, or small. Large subwoofers are powerful and ideal for large rooms, while small and compact ones are perfect for small rooms. Compact subwoofers are easy to install, move around, and store. This makes them a popular choice for people with small spaces.

How to Choose Home Theater Amplifier Subwoofer

The following are some of the essential things to keep in mind when buying a home theater subwoofer amplifier.

• Sound Quality

When selecting a subwoofer amplifier, the sound quality should be a top priority. Because the subwoofer is in charge of the low-frequency sound, one must consider the sound quality. The amplifier's frequency response, total harmonic distortion (THD), and signal-to-noise ratio are crucial factors to consider. The lower the frequency response, the deeper the bass the amplifier can produce. The lower the THD and the higher the S/N ratio, the cleaner the sound will be.

• Power and Performance

When selecting a subwoofer amplifier, performance should be one of the determining factors. The amplifier's RMS power output is essential to consider. The RMS power refers to the amount of power the amplifier can provide to the subwoofer continuously. Select an amplifier that can provide a power range within the subwoofer's suggested RMS value for optimal compatibility and performance. Furthermore, when determining the power of the amplifier, one must also consider the impedance. Select an amplifier that can support the subwoofer's impedance and provide power within the suggested RMS range for the best performance.

• Size and Type

When purchasing a subwoofer amplifier, one must consider the size and type of the subwoofer. The size of the subwoofer must be selected according to the size of the room and the audio quality required. Larger subwoofers may produce deeper bass, but the smaller ones are more accessible. Furthermore, when selecting a subwoofer, one must also consider whether it is passive or self-powered. The self-powered subwoofer includes an inbuilt amplifier, while the passive subwoofer must be connected to an external amplifier to function.

• Wired or Wireless

When purchasing a subwoofer, it is essential to determine whether it is wired or wireless. A wired subwoofer must be connected to the receiver with cables, while a wireless subwoofer can connect to the receiver through Bluetooth or Wi-Fi. The subwoofer will be located in the room, and the layout of the room will determine the type of subwoofer needed. Furthermore, wired subwoofers produce better sound quality, while wireless subwoofers are more convenient and easier to install.

• Budget

One must also consider the budget. A wide range of subwoofers is available at different price points. When selecting a subwoofer, one must consider the features and sound quality that are most important and choose a subwoofer that fits the budget.

Q & A

Q2. What size subwoofer is best for home theater?

A2. A 12-inch subwoofer delivers the best of both worlds. It can hit the lower ranges well while also providing good clarity and detail in the midrange.

Q3. How many watts should a home theater subwoofer have?

A3. A larger room or the desire for higher-volume listening may require 100 to 150 watts or more. A more powerful subwoofer with a larger internal amplifier and a larger driver will deliver more bass at any volume level.
