10 thin soundbars that will fit under the TV


In order to adapt to the specifications of the latest televisions, which are increasingly low and borderless, audio manufacturers are increasing their efforts to offer ever thinner soundbars. Thickness is now an essential factor when choosing a soundbar that can be integrated under a new generation TV without masking the bottom of the screen. After studying the latest generation of TVs, we have concluded that the maximum height of a soundbar should be around 6cm. Therefore, here is a look at slim soundbars ideal for use with the latest generation of TVs. Are they as efficient as larger models?

A soundbar less than 6cm thick like the Panasonic SC-HTB250EG can easily fit in front of a new television without covering the bottom of the screen.

Why choose a slim soundbar?

While the image quality of televisions continues to improve with OLED, QLED, QD-OLED and even Mini-LED technologies, sound often remains their Achilles’ heel. A soundbar is therefore the simplest and most harmonious way to substitute the sound of a television and enjoy a truly immersive and sometimes even spectacular listening experience. Aesthetically speaking, there are different types of soundbars. Most of them measure between 80 and 120cm long and are 5 to 15cm high. However, modern TVs adopt lowered feet, and the absence of a frame limits the space available under the TV. To avoid hiding the bottom of the screen, the height of soundbars is reduced from generation to generation. The thinnest models are now less than 6cm thick to fit perfectly in front of and/or under televisions.

With a height of just 3.5cm, the Philips Audio TAB6305 soundbar leaves the TV screen completely free.

The performance of compact soundbars

Ultra-thin soundbars range from simple stereo models to versions capable of delivering true 5.1, 7.1 or even Dolby Atmos/DTS:X sound. All variants exist, resulting in a more or less enveloping spatialization. The most compact soundbars such as the LG QP5 (5.9cm high and 29cm long) and JBL Bar 2.0 All In One (5.8cm high and 61cm long) offer stereo sound with at least two drivers. These 2.0 and 2.1 stereo soundbars (with subwoofer) generally adopt a digital processor (DSP) responsible for widening the soundstage by creating virtual surround sound. Most often, these compact soundbars are sold together with a wireless subwoofer to provide a more spectacular sound experience.

The JBL Bar 2.0 All In One soundbar uses JBL surround sound technology to create a sound bubble, while reducing the size as much as possible.

The most powerful silm soundbars manage to maintain a height of less than 6cm, while delivering true 3D sound in Dolby Atmos or DTS:X. To do this, these soundbars adopt a more elongated design in order to incorporate a maximum of drivers, including on the top panel for vertical effects. The load volume is also maximized, for better bass performance. A few models, like the Bose Soundbar 900, even manage to provide powerful and deep bass without the need for an external subwoofer. They are therefore ideal for enjoying a true cinema experience, from a single piece of equipment that can be placed in front of the television. These longer models are often intended for televisions with a screen size of at least 43” (108cm).

The Bose Soundbar 900Dolby Atmos soundbar offers powerful, deep bass while maintaining a reduced thickness to leave the screen fully visible.
