The Q950A soundbar offers a nice blend of a felt finish and a metallic grille, and is slim enough to fit under most TVs though the display is on the top surface rather than front-facing, which makes reading it more difficult than need be.

Taking in all the speakers, the Q950A is almost identical to its predecessor apart from the rear speakers, which Samsung has added more drivers to. With more drivers spreading out sound in different directions, they need some space to operate if they’re being used on a bookshelf, for instance. that can be read for. The subwoofer is large and takes up space, but considering the oomph provided by its 8-inch driver, it’s worth accommodating.

The speaker set-up is an 11.1.4 channel, which is more than the LG SP11RA below, and powered by a substantial 600W of power with support for Dolby Atmos or DTS:X immersive audio formats. For home cinema enthusiast looking to plug sources into the bar itself, HDR10+ and Dolby Vision HDR formats can be pass through the bar if you’ve run out of HDMI inputs on the TV. There’s no support for VRR or 4K/120Hz that the latest consoles take advantage of.

Wireless connectivity stretches to Bluetooth, AirPlay 2 and Wi-Fi. For those with relatively new Samsung TVs, there are exclusive features such as SpaceFit sound, which calibrates the soundbar’s output to a room’ dimensions. There’s also the Active Voice Amplifier that boosts volume levels and make voices more prominent to compensate for ambient room noise.  

With the addition of two extra channels, our reviewer found that it heightened the sound of this soundbar even more than the previous model. We found there was greater presence to rear channels than before, along with a better sense of width to that area of the soundstage. At the time of review, we felt the Q950A offered the most immersive audio experience from a soundbar package so far.

The main soundbar and subwoofer deliver an emphatic performance, utilising the heft and power with no trouble filling our large test room. The subwoofer is able to reach lower frequencies than previous Samsung bars we’ve tested, integrated well with the bottom of the midrange and sounding a cohesive part of the frequency range.

The LG SP11RA features a great sense of height in the soundstage that it creates, especially with Dolby Atmos soundtracks. Our reviewer felt that the way in which the surround system positioned effects was arguably one of the best performances in terms of steering audio in front of the listening position, offering more clarity and precision than the Q950A produces.

The SP11RA was able to fill almost all corners of our test room with ease, which we found remarkable from such a slim unit. Dialogue come across with crystal clear clarity, the system revealed plenty of detail from movie soundtracks we tested and the subwoofer felt integrated within the mix, producing a forceful low end.

We found using the AI Sound Pro processing helped expand the soundstage and produce a more aggressive presentation, bringing an Atmos-style presentation to non-immersive sources. We did find that, on occasion, it can stress treble sounds a little too unnaturally. Where the Q950A gains the upper hand is that the LG doesn’t quite create an entire hemisphere of sound, so while the performance from the front speakers is great, there’s less a sense of sound around the sides of a room. 

With a total of 7.1.4 channels, the SP11RA features an enormous 770W to power all the speakers. New features include the Meridian Horizon mode that aims to turn two channel content into more immersive multi-channel audio. Elsewhere the SP11RA can pass-through Dolby Vision and HDR10 formats, though the lack of HDMI 2.1 support may disappoint gamers looking to pass-through 4K/120Hz games. Google Assistant, Siri and Alexa voice control are supported if you want the option of hands-free operation.

The SP11RA’s slim profile should fit under most TVs without a hitch, the rear speakers are compact, and while the subwoofer is on the large side it is slender enough that it can fit beside a sofa or under a sideboard.

The Sonos Arc is one of the best Dolby Atmos soundbars we’ve tested, and when paired with rear speakers and a subwoofer it creates an impressive surround system that does come at a premium price. 

On its own the Arc is a 5.0.2 system, with the Sonos Sub and rear speakers transforming it into a 7.1.2 channel set-up.  S2 compatible Sonos speakers are required for the rear channels, so the One SL or Five speakers are an option along with the Ikea Symfonisk Bookshelf speakers, while any generation of Sub can be partnered with the main Arc bar. 

The audio performance is one we found impressive when all hooked up, with Trueplay helping to align and balance the speakers for optimal sound within the room. The rear speakers help to fill in the gaps behind the seating position, providing a subtle assist that engaged us more than the front-heavy performance of the Arc. The integration of the rear speakers is well handled, blending in well to create an expansive hemisphere of sound.

The addition of the Sub provides an impressive low end than you got with the Arc, helping to alleviate the Arc’s issue with transitioning between the bottom end of the frequency range to the mid-range. As the Sub is left to do the heavy lifting, the Arc can focus on the midrange, which we felt helped aid smoother transitions between bass and midrange. Depending on the size of the room, a Sonos Sub may feel too powerful, and the cost of it adds to the overall outlay. With the Sonos Sub mini in the works but not officially announced, that may be more of solution for those who want a bigger bass in a compact form.
