Active vs Passive Soundbar: Which Do You Need?

What active and passive mean on a soundbar listing

The terms active and passive describe whether a soundbar contains its own amplifier. An active soundbar, also called a powered soundbar, has an amplifier built into the cabinet. It can be connected directly to a TV and produce sound without any additional equipment. A passive soundbar has no amplifier inside. It is essentially a set of speakers arranged in a bar-shaped enclosure and must be connected to an external amplifier or AV receiver to produce sound.

This distinction is one of the most important details to check when reading a soundbar listing. An active soundbar is a complete system in one box. A passive soundbar is a component that requires other equipment to function. The listing title or bullet list usually states which type a product is, often using the words powered or active for the first type and passive or unpowered for the second.

Active soundbars: the all-in-one solution

Active soundbars are the most common type sold today. Brands such as Bose, Sonos, Samsung, LG, Hisense, Polk Audio, and Creative all sell active models. Because the amplifier is built in, the soundbar only needs a power cord and a connection to the TV. That connection is typically HDMI ARC or eARC, which carries audio from the TV to the soundbar and allows the TV remote to control the volume. Optical and Bluetooth connections are also common on active soundbars.

An active soundbar may also include a built-in subwoofer or come bundled with a separate wireless subwoofer and rear speakers. The amplifier inside the bar powers all the speakers in the package. This makes active soundbars a straightforward choice for anyone who wants to upgrade TV sound without adding extra components. The best soundbar guide covers active models across different price ranges and feature sets.

Active soundbars vary in channel layout from 2.0 to 5.1.2 and beyond. The channel count tells you how many speaker drivers are inside and whether the bar supports formats such as Dolby Atmos. The soundbar channels explained article explains how to read those numbers on a listing.

Passive soundbars: require an external amplifier

Passive soundbars are less common and are typically sold to buyers who already own an AV receiver or plan to build a traditional home theater system. Because the bar has no amplifier, it must be connected to a receiver or amplifier using speaker wire. The receiver handles amplification, audio decoding, and input switching. This setup is similar to how passive bookshelf or floor-standing speakers work in a surround sound system.

A passive soundbar offers flexibility in component choice. You can pair it with a receiver that supports the features you want, such as Dolby Atmos, DTS:X, or multiroom audio. You can also upgrade the receiver later without replacing the speakers. However, this approach requires more space for the receiver, more cables, and a basic understanding of how to connect speakers to an amplifier. The soundbar vs home theater receiver article compares the two approaches in more detail.

Denon is one manufacturer that sells both AV receivers and soundbars. A passive soundbar paired with a Denon AVR is one example of a receiver-based setup. The receiver handles all audio processing and power, while the soundbar serves as the front speaker array.

How to identify active vs passive on a listing

The listing title is the first place to check. An active soundbar often includes the word powered or active in the title or bullet list. A passive soundbar may include the word passive or unpowered, or it may state requires external amplifier or for use with AV receiver.

The connections listed also give clues. An active soundbar lists HDMI ARC, eARC, optical, or Bluetooth as input methods. A passive soundbar lists speaker wire terminals or binding posts, similar to a passive speaker. The box contents section of a listing may also help: an active soundbar includes a power cord and sometimes HDMI or optical cables, while a passive soundbar includes no power cord because it draws power from the receiver.

If a listing does not clearly state whether the soundbar is active or passive, check the manufacturer page for the model. The product specifications on the maker site will state whether an amplifier is built in. The soundbar connectivity options article explains how to read connection details on listings.

Setup and connections: what each type needs

An active soundbar requires two connections to function: a power cord plugged into an outlet and an audio connection from the TV. The audio connection is most often HDMI ARC or eARC, which carries audio from the TV and allows the TV remote to control the soundbar volume. Optical is an alternative if the TV lacks HDMI ARC. Bluetooth can be used for streaming music from a phone or tablet, but it is not a replacement for the TV connection. The best HDMI ARC soundbar guide lists active models that use this connection.

A passive soundbar requires speaker wire from the bar to the amplifier or receiver, plus a power cord for the receiver. The receiver then connects to the TV via HDMI. The receiver handles all audio switching and decoding. This setup adds several steps: you need to match the impedance of the soundbar to the receiver, connect the speaker wire with correct polarity, and configure the receiver to send the right audio channels to the bar.

For most people buying a soundbar as a TV audio upgrade, an active model is the simpler and more practical choice. The best soundbar guide covers active models across price ranges.

What to pick for your situation

The choice between active and passive depends on your current equipment and how much complexity you want. The table below matches common situations to the type of soundbar that fits best.

What to pick for your situation

Questions

Can I use a passive soundbar without a receiver?

No. A passive soundbar has no amplifier and cannot produce sound without an external amplifier or AV receiver. The receiver provides power to the speakers and handles audio decoding.

Are all soundbars active?

No, but the majority are. Active soundbars dominate the market because they offer a simple all-in-one solution. Passive soundbars are a smaller category aimed at buyers who already have a receiver or want a custom home theater setup.

Do active soundbars sound worse than passive?

This article cannot compare sound quality. Both types can produce good sound when paired with appropriate equipment. The choice depends on your setup preferences, not on a general rule about which sounds better.

Can I add rear speakers to an active soundbar?

Many active soundbars support wireless rear speakers that are sold separately or as part of a bundle. Check the listing for rear speaker compatibility. The best soundbar with rear speakers guide covers models that support this.

What cables do I need for an active soundbar?

An active soundbar needs a power cord and an audio cable to the TV. HDMI ARC or eARC is the recommended audio connection. Optical is an alternative if the TV lacks HDMI ARC. Some models include these cables in the box.

Do passive soundbars need a separate amplifier for each channel?

No. A single multichannel AV receiver powers all the channels in a passive soundbar. The receiver has one amplifier section that drives all connected speakers.

Is a soundbar with a separate subwoofer still active?

Yes, if the main bar has a built-in amplifier. Many active soundbars come bundled with a separate wireless subwoofer that is self-powered. The main bar still contains the amplifier for its own drivers.

Which is better for a home theater system?

It depends on your goals. An active soundbar is simpler and takes up less space. A passive soundbar paired with a receiver offers more flexibility for upgrading components over time. Both can be part of a home theater setup.
