Remote-free control divides opinion. TV-remote and app control are convenient for many users, but several testers still wanted a dedicated physical remote.

6 supporting reviews

KEF XIO

The XIO is formidable as a one-box home-theater solution, but current expansion is limited by the absence of dedicated wireless surrounds. That makes it less flexible than ecosystems built around add-on rear speakers.

3 supporting reviews

Marshall Heston 60

The Heston 60 works well as a compact one-box TV solution, but its home-theater ecosystem is less expandable than rivals because rear channels are not supported.

Wireless rear-speaker expansion remains a weakness because the promised bespoke satellites have not yet arrived and no confirmed timeline was available.

1 supporting review · Limited evidence

Marshall Heston 60

Rear-speaker expansion is a clear weakness: there are no matching rear channels, so owners cannot build the same kind of wraparound system available from Sonos and some other rivals.

4 supporting reviews

KEF XIO

Wireless subwoofer integration can be stable and delay-free, but broader speaker expansion remains uneven: some options require an extra adapter and promised rear connectivity still lacks a firm timeline.

Wireless subwoofer linking can be easy and stable once established, but some setups experienced initial pairing friction. Marshall’s broader speakers also do not integrate with the soundbar as a unified ecosystem.

4 supporting reviews

KEF XIO

The XIO can create convincing scale and envelopment even in smaller rooms, so it does not need a huge space acoustically. Its physical width still needs to fit the furniture and TV.

2 supporting reviews

Marshall Heston 60

This is particularly well suited to small and medium rooms, where its compact footprint still produces surprisingly full, powerful sound.

12 supporting reviews

KEF XIO

Fine detail is a standout strength, from subtle debris and ambience in movies to instrument texture and low-level information in music. Complex scenes stay unusually easy to follow.

17 supporting reviews

Marshall Heston 60

Fine details come through clearly, helping subtle effects, textures and small soundtrack cues remain audible in busy scenes.

The built-in bass is strong enough that many users may skip a subwoofer, but adding one can deepen impact, improve scale, and offload the lowest frequencies. Integration is generally easy, though cost can rise quickly.

11 supporting reviews

Marshall Heston 60

The Heston 60 has enough bass to work well alone, while the optional Heston Sub 200 adds deeper cinematic impact. The matching sub is useful but expensive, and a few testers wanted even more power.

Spatial positioning and imaging are precise, with movement across the screen and individual elements placed clearly within the soundstage.

2 supporting reviews

KEF XIO

Bass is one of the XIO’s defining strengths: deep, punchy, controlled, and unusually substantial for a single bar, often enough without a subwoofer. A few listeners wanted tighter or deeper sub-bass, and one negative test heard compression and resonance when pushed.

27 supporting reviews

Marshall Heston 60

Bass is one of the Heston 60’s biggest surprises, with unusually strong punch and weight for such a small bar. Deep sub-bass still benefits from an added subwoofer.

13 supporting reviews

KEF XIO

Dialogue is usually exceptionally clear, centered, and easy to understand even during busy scenes or at modest volume. A small minority heard muffled, chesty, or partially buried voices with certain material.

21 supporting reviews

Marshall Heston 60

Dialogue is usually crisp, well separated and easy to follow, even in dense action. A few tests found speech could become muddied when background activity became especially busy.

10 supporting reviews

KEF XIO

The low profile helps the XIO sit beneath a TV, but its roughly 47–48-inch width and substantial depth demand a wide stand and generally look best with a 55-inch-or-larger screen. Wall mounting reduces the visual bulk.
