Passive Soundbar Buying Guide

Sound Performance

Does the system have any sound modes? Can the passive soundbar self-optimize to give excellent sound that varies according on the media you play? The sound quality of the sound bar should be your top priority when choosing speakers, not aesthetics. Your passive soundbar won’t be an improvement over your factory TV speakers if it doesn’t have a higher resolution.

There are sound modes with pre-programmed settings that make some stuff stand out. For better explosions, some passive soundbars’ movie mode, for instance, would boost the dynamic range and concentrate the bass. Also, it will focus on making speech more understandable so that you never miss a conversation’s dialogue and can always reflect on what is said.

Some passive soundbars can also automatically optimize themselves to give the optimal performance for the content to assure the sound quality even without sound modes. A dedicated center channel will improve speech in addition to sound modes so you never miss a whisper. In addition to the center channel, you may find speech-improving features like Clear Voice to clearly pronounce all of the dialogue that is presented onscreen.


One thing I always verify when using soundbars for evaluations is the number of channels they support. In general, soundbars can provide 2 to 9 channels. The industry standard for real surround sound is 5.1 channels, and any number higher enhances the sound effects and quality.

That is not to imply, though, that home theater equipment made with a smaller channel number cannot provide immersive quality. A nice system can typically be obtained with two- or three-channel soundbars like the KEF HTF7003. But more on that later. Some well-known soundbars have cutting-edge audio technology that can replicate genuine surround sound without a full 5-channel configuration.

Modern Audio Technology

It is advisable to check for soundbars that can decode DTS and Dolby technology. These two terms are the pinnacle of cutting-edge audio capabilities and the gold standard for superior performance in their respective fields.

Soundbars with fewer channels can replicate the effect of digital surround sound with the aid of DTS and Dolby technology. The latest sound technologies will simply increase the strength of the drivers and already-present immersive effects with a full 5-channel system setup or more.

Products made with brand-specific technologies, such as Sony’s S-Force and LG’s Meridian, may also be seen. For a full theatrical experience at home, soundbars that employ more modern technologies would bring professional-grade technology with you.


A passive soundbar is constructed with both wired and wireless connectivity, much as an active soundbar. In contrast to alternative wired connections, using HDMI is advised by our experts across all of our reviews because it has the capability to support higher quality transmissions. The best alternative to HDMI for some TVs is digital optical, which can likewise decode high-quality audio but lacks the return channel.

Active soundbars frequently have wireless technologies like Bluetooth and Wi-Fi, while passive ones might also have them. Users can stream content from external devices directly through the soundbar by utilizing wireless connectivity options.

Soundbar Position

Compared to surround sound speakers, soundbars save more space. These can typically be set on a tabletop or hung on a wall, depending on whatever option seems easiest to you. The soundbar should be positioned a bit below eye level for optimal performance. Consider where you would like to set it. You can utilize the receiver to its fullest potential in this manner as well.

Placing or mounting your soundbar on the wall directly beneath your flatscreen is quite simple for TVs that are mounted to the wall. You can position a passive or active soundbar in front of the TV’s base stand if it is free-standing. But, you must watch out that it doesn’t block the remote sensor otherwise the IR receiver won’t receive orders.

You have additional placement flexibility if your soundbar uses wireless technology. You can experiment with the position you prefer to find the optimal configuration for every room in your house if there are other moving parts you need to connect, such as subwoofers and rear speakers. Be sure the positioning will work well with the acoustic panels you have in your room.


To choose the ideal spot, you should also consider the size of your soundbar and the components of your current home theater system. To create an immersive experience, the general rule is to set the soundbar right in front of you and distribute the remaining components evenly throughout the space.

The cost is justified by the fact that passive soundbars typically perform far better than active ones. This is due to the fact that an external amplifier can provide audio that is both clearer and louder than an active soundbar. A passive soundbar, on the other hand, offers significantly more customizing options if you are an enthusiastic audiophile or cinephile who is seeking more than just a straightforward upgrade from basic TV speakers. Check out low-cost home entertainment systems that are nonetheless functional.


Subwoofers, in the opinion of our audio professionals, are essential to accurately convey the quality of a soundbar. The bass notes in your content won’t be as audible without one. A subwoofer’s resonant bass can be appreciated by fans of music and movies.

The subwoofer may be an internal or external component of the device. A soundbar with an integrated subwoofer, like the KEF HT7003, can nevertheless enhance the bass in a tiny room, albeit not as significantly as an external one. On the plus side, you won’t want a huge wireless subwoofer to fill a little space.

A soundbar with an integrated external subwoofer can reveal all the previously hidden deeper tones if space is not an issue in your home. The soundbar can be be mounted on the wall if you choose.

Frequently Asked Questions

What is a passive soundbar?

Soundbars with no built-in amplifier are known as passive soundbars. A passive soundbar is a gadget that requires an external A/V receiver and amplifier to function. It allows you to pair it with a variety of sound management systems and allows you to experiment with different speaker-amplifier combinations or non powered soundbar.

Passive soundbars, unlike active (powered) soundbars, cannot produce sound. The home theater experience have to get it from somewhere else. This means that the passive soundbar will only create sound when connected to a sound system.

Do passive speakers sound better?

Passive speakers do, in fact, sound better. This is owing to the external receiver and amplifier, which produces clearer sound and focuses on output rather than power. Amplification is required for active speakers to function. The speaker’s amp or built-in amp may contribute a small degree of distortion. Passive speakers have no built-in distortion because they do not use amplification.

Aside from the possibility of amplifier distortion, the fact that active speakers run at a greater powerpoint than passive speakers in the same space causes them to behave in a non-linear manner. That is, when you operate the speaker near the top end of the power curve, the real power curve causes the speaker to provide less output than would be expected. Also, if the amplifier uses companding to provide anti-feedback, the speaker may respond well to high frequencies but poorly to low frequencies.
