With their huge channel counts, vast amounts of power and peerless knack for creating ultra-immersive three-dimensional surround sound stages from Dolby Atmos and DTS:X soundtracks, Samsungs flagship soundbars have been firm favourites with AV fans for years now. For the past two or three generations, though, while there have always been improvements, the annual changes have been relatively small. For its 2025 models, though, the brand is ringing in some truly significant changes.The Samsung HW-Q990F soundbar features a radical new subwoofer design and new AI sound optimisation ... [+] feature.Photo: SamsungAt the very top of Samsungs 2025 soundbar tree will be the HW-Q990F. This successor to the multi award-winning HW-Q990D marks a major departure from its predecessor by swapping Samsungs usual hefty, acoustic lens-sporting subwoofer with a single 8-inch driver for a new 300W cubic bass speaker design that carries an 8-inch dual active unit, where the two drivers sit on opposing sides. This new design results, Samsung claims, in reduced unwanted resonance and a frequency response as low as 32Hz from a unit thats only around half the size of its predecessor.As well as hopefully improving the Q990Fs low frequency performance, the new subwoofers much smaller design obviously makes it easier to tuck its away out of sight in your designer living room. Though if you cant completely hide it away, it also features a smoother, more refined finish than its predecessors.Detail of the newly designed main bar component for the Q990F soundbar.Photo: SamsungThe Q990F system benefits, too, from Samsungs obsession with AI by introducing a number of AI-based sound optimisation features. A Dynamic Bass Control system enhances low frequency clarity by constantly applying non-linear bass management, while an AI-updated version of Samsungs Active Voice Amplifier Pro system uses real-time content analysis to reduce background noise and make dialogue clearer.MORE FOR YOUSamsungs Q-Symphony feature, where the soundbar can share audio duties with the speakers in compatible Samsung TVs, has also been AI-enhanced for Samsungs 2025 soundbars so that it can take on three additional wireless speakers rather than two, and autodetect the position of those other wireless speakers such as Samsungs Music Frames in order to optimize the sound stage to take account of each speakers distance from and relative angle to a Samsung TV.The latest Q-Symphony system also enables the Q990F to draw on a new Neural Processing Unit in Samsungs latest TVs to further enhance dialogue and improve synchronisation between the growing number of audio components the soundbar can combine with.In its solo form, the Q990F will continue to deliver an 11.1.4 channel count from its combination of a main soundbar, the new subwoofer, and two multi-channel wireless rears that include up- and side-firing drivers alongside the regular forward-facing driver.The new Samsung HW-QS700F soundbar can be hung vertically on the wall or placed horizontally on a ...
