FAQ Section

What is a Passive Soundbar ?

A soundbar is a great way to upgrade your TV’s sound. It replaces the thin factory-installed speakers of your flat-panel TV and makes the audio more robust and dynamic. A soundbar may be active or passive. An active soundbar comes with built-in crossover components and an integrated amplifier. A passive soundbar needs to be connected to an external A/V receiver and amplifier. An active soundbar offers a comprehensive solution for your audio needs. It houses all the sound components in a single enclosure. A passive soundbar, on the other hand, offers unbeatable scalability. You can club it with any crossover setting and sound management system. You can experiment with different speaker-amplifier combinations and add as many amplifiers as you want. You can also upgrade or downgrade your system as you like with minimal hassle. In short, a passive system gives you the freedom to work your sound system any way you want. Plus, it is inexpensive and generally doesn’t burn a hole in your pocket.

A soundbar is a sound system with an array of speakers inside a single slender cabinet. An active soundbar has built-in amplification and digital signal processing. It is more or less self-sufficient and does not require additional support, other than maybe a subwoofer. A passive soundbar does not have internal amplification and digital signal processing. Its drivers need to be powered by an external amp or AV receiver. It is not a single-unit system and requires the support of additional devices. To work a passive soundbar, you need to have a fundamental understanding of how sound systems work. Passive bars tend to have a complicated set-up and if you don’t have some basic knowledge about them you might feel a little lost. You can add any amplifier/receiver you like, and connect with more number and types of sources. You can decode a large number of audio formats, and play around with different crossover settings to get the best soundbar-subwoofer combination. If you want to try out a different bar-amp combo, just get the right amp and crossover settings that suit your requirement, and make the switch. You won’t have to buy a brand new sound system to do this. Passive soundbar are also a cheaper option if you already have an amplifier. While pairing a passive bar with an amp, note their power ratings and impendences. You want to make sure they are compatible if you don’t want to be stuck with bad audio. While they have their advantages, passive soundbars are not without drawbacks. For one, they can be quite cumbersome and difficult to manage, store and transport. As they involve multiple devices and lots of wires, they occupy more space and have a cluttered look.

Know how before selecting a Passive Sound bar for your audio setup :

While buying a passive soundbar, take note of the speaker configuration and capacity. Keep in mind how you wish to set up the bar in terms of receiver, amplifier and additional speakers. Look for the appropriate inputs and outputs, number of channels, sound technology, etc that will support your set up. Also consider your TV’s screen size. The soundbar must match the TV in width or it can be a tad smaller. If it is longer and sticks out of the edge of the TV screen, it will look odd. Furthermore, you need to plan ahead where you wish to install the soundbar, and accordingly choose the right size, color and shape.

How is a passive soundbar different from an active soundbar ?

The main difference between a passive and an active soundbar is that the former does not have a built-in amplifier whereas the latter does. A passive soundbar only has speakers (which might be a combination of woofers, mid-range drivers, full-range speakers and tweeters). It needs a separate amplifier or receiver to power itself. An active speaker, on the other hand, comes pre-fitted with an amplifier and is a single all-in-one self-powered unit.

A passive speaker is generally more expensive than an active one, which is surprising considering it lacks an amplifier. But the truth is that passive soundbars have high-quality drivers far better in design and durability than active soundbars. Hence, even though active bars have built-in amplification, their cost is relatively low.

A passive soundbar is more complicated. You will need a basic understanding of sound systems to be able to set it up on your own. It is preferred by audiophiles who wish to personalize their home entertainment systems. A powered soundbar has a simple plug-and-play functionality. It is ideal for people who are only looking to improve their TV sound and want a hassle-free solution.

Being a set of two units, a passive soundbar requires more space. But it is lighter and easier to upgrade than an active bar. If an active soundbar breaks down, the entire gadget has to be replaced. But if a passive soundbar breaks down, only the soundbar has to be replaced while the amplifier can stay the same and be used to drive the new soundbar.

Buying Guide of Passive Soundbar :


The first thing you need to consider while selecting a passive soundbar is the number of channels. The larger your room, the more the number of channels you will need. For an average-sized living room though, a 3-channel soundbar with left, right and center channels is fine. But, if you want true surround sound, a 5- or more channel soundbar would be a better choice.

Dolby Digital and DTS technology

Make sure your soundbar supports the latest sound formats. Dolby Digital and DTS are the standard codecs at the moment. They lock dialogues to the screen and place sounds at precise points across the room for a realistic sound experience. You can also consider Dolby Atmos and DTS:X if budget is not a constraint. These technologies offer true surround sound with overhead effect and automatic sound adjustments according to the size and layout of the room.

Sound mode

A lot of soundbars come with pre-set sound modes that optimize the soundtrack based on the content. For instance, Movie Mode elevates dialogues and special effects. Music mode enhances the notes of different instruments, no matter how high or low, with precise placement. Therefore, it might be a good idea to get your hands on a gadget that is able to do justice to all kinds of audio.

TV screen size

Another important factor to consider is the size of your TV screen. For cleaner aesthetics, it is advisable to get a soundbar that has the same width (or length) as your TV or is a few inches shorter. If it protrudes outside the TV’s edge, it can look odd.


Where you want to place your soundbar is another crucial factor. If your TV is on a wall, the soundbar can go underneath it, or above, as you prefer. But if the TV is on a media console or table, the soundbar has to be such that after it is installed in front of the TV on the same console/table, it does not block the TV’s remote sensors and screen. Here the height of the soundbar is key. If your TV stand is not too high, you might have to go for a slim-profile soundbar.


Do check if the soundbar has the necessary ports to connect with your TV, amplifier/receiver and/or other devices like subwoofer. An added advantage is if it also supports HDMI. It will simplify the connection with the TV and you will be able to send signals using a single HDMI cable.


If you want bigger bass, we suggest you buy a soundbar-subwoofer combo. You can place the bar near the TV and the sub can be placed next to the couch. Subs are available in wired and wireless variants. If sound quality is your priority and you don’t mind the extra wiring, you should buy a wired sub. If you want a clutter-free installation and freedom to place the sub anywhere you want, a wireless sub is recommended.

Compatibility with amplifier

If you already have an amplifier, make sure the power handling capacity of the soundbar matches the amplifier power. This is where your technical know-how will come into play. We suggest you do some research online and also speak to a couple of dealers before making a purchase.
