Top 5 Best Stereo Speakers in 2025

1.Q Acoustics M40 HD

Last update on 2025-03-14 / Affiliate links/images from Amazon.

To many die-hard music fans, the arrival of the Q Acoustics M40 HD will be like finding the holy grail: floorstanding speakers that don’t take up much space (they’re gloriously svelte) and don’t require separate amplifiers to clutter up your den. Built on the success of the excellent M20 HD (listed below, at number three in this buying guide), the M40 HD takes things to the next level – and does an outstanding job of relaying your music, no matter how you listen.

These are powered speakers (a’master’ with amplification for both towers and controls on the top plate, and a’slave’ speaker) that provide wired and wireless connectivity, as well as hi-res audio capability via the digital optical and USB-B inputs. Most households will be more than satisfied with 200 watts of power, which includes Q Acoustics’ renowned Continuous Curved Cone (C3) driver as well as aptX HD and aptX Adaptive over Bluetooth.

OK, some users will be disappointed by the lack of wi-fi action or a control app, but there’s more than enough to be excited about for this price – and in terms of sound quality, they’re a zealous and articulate listen, as long as you give them some room to operate and don’t position them too close to a rear wall.

The M40 HD loudspeakers have a decoupled tweeter above two Continuous Curved Cone (C³) mid/bass drivers, similar to those found in the company’s more expensive and award-winning 5000 series. Each has a bass reflex port at the bottom of the cabinet’s back to improve low-frequency presence and punch. However, after that, they differ slightly.

In the case of the ‘secondary speaker’, the only other feature is a pair of speaker-cable binding posts just beneath that reflex port. The ‘primary’ speaker, by way of contrast, has plenty more going on.In addition to speaker binding posts, the ‘primary’ speaker’s rear plate includes a mains power output. It also has a pair of stereo RCA analogue inputs, a 3.5mm auxiliary socket, and digital optical and USB-B inputs, the latter of which can digitally process incoming digital audio files with resolutions of up to 24bit/192 kHz. There is a switch that indicates whether the speaker is on the left or right side of the setup, as well as whether it is in open space, against a wall, or in a corner. There’s also a pre-out for a subwoofer for those who are truly antisocial.

In contrast, wireless connectivity is limited to Bluetooth. It’s version 5.0, which supports SBC, AAC, aptX HD, and Low Latency codecs. Some Wi-Fi connectivity would be nice, but it appears that Q Acoustics has balanced the feature set against the eventual price and arrived at a satisfactory balance.

The ‘primary’ speaker also takes care of amplifying both speakers (these are ‘powered’, rather than truly ‘active’ beasts). It features two Class D blocks of amplification, each of 100 watts. The M40 HD is supplied with a length of cable to connect the two speakers together – this, along with a connection to mains power, is the only wiring this wireless system requires.

It becomes apparent after next-to-no listening that the Q Acoustics M40 HD prefer to be out in just a little open space, not hard against a rear wall, and toed in just a little towards your listening position. They don’t throw in the towel if some or all of this is not possible in your space, you understand – but like all of us, they have their preferences.

And when they’re positioned perfectly, connected via Bluetooth to a Samsung Galaxy S23 smartphone running the aptX HD codec, and playing a TIDAL-derived file of Grace Jones’ Pull Up to the Bumper, they’re a simple and enjoyable listen. There are numerous aspects of music production that deserve to be mentioned, but what stands out the most is how engaging and upfront the M40 HD is. This system sounds like it enjoys your favorite music just as much as you.

2.Dali Rubikore 2

Last update on 2025-03-14 / Affiliate links/images from Amazon.

The Dali Rubikore 2 are small stand, shelf, or furniture-mounted loudspeakers. They demonstrate Dali’s desire to make high-end audio technology more accessible. They aim to provide premium sound quality at a more affordable price point by incorporating advancements from Dali’s exorbitantly expensive Kore series.

These speakers are loaded with features, including a 6.5-inch mid-bass driver that uses Dali’s Clarity Cone technology. A soft dome tweeter ensures accurate high-frequency reproduction, while a rear-firing bass port with a continuous flare design helps to produce deeper bass.

The Rubikore 2 features a sleek design with gently curved front and rear panels and comes in four different finishes. The cabinets, measuring 350 x 195 x 335 mm and weighing 10.5 kg each, are braced for a solid and refined appearance and build.

In terms of sound, the Dali Rubikore 2 impressed us with its bass extension and tonal accuracy, providing a balanced and engaging listen that we described as “consistently good fun” in our review. At times, the soundstage lacked depth when compared to competitors. Overall, the Rubikore 2 is an excellent value for anyone looking for high-quality audio in a small package, which is why we recommend it as our top all-around choice for most people looking for a versatile speaker system.

The Dali is not as sophisticated as powered or active speakers, but given its small size and use of well-established materials, there is a surprising amount going on inside. Dali used the massive amount of data gathered durig the development of the Kore speaker to improve the Rubikore models. Obviously, many aspects of a speaker do not make it to this level, but a few ideas do.

This is most apparent in the drivers. The Rubikore 2 uses a 6.5inch (155mm) mid bass driver that employs technology that Dali refers to as Clarity Cone. The cone itself is made from Dali’s preferred wood fiber; something that have been doing for a very long time but here you can see a pattern on the cone itself. This increases the stiffness of the cone as a whole and improves the breakup behaviour. Behind the driver, Dali’s Soft Magnetic Compound is used as it reduces eddy currents and other unwanted effects, lowering distortion overall.

This driver benefits from a rear-firing bass port with a continuous flare along its length. This helps to keep the flow of air out of the port quieter by increasing the diameter as the air accelerates and expands. This port allows the Rubikore 2 to measure frequencies as low as 50Hz at +/-3dB, which is a usefully demanding method of measurement.

This mid-bass driver is paired with a soft dome tweeter designed to reduce mass, which is a highly desirable feature in a high-frequency driver. Traditionally, tweeters were cooled with ferrofluid, which adds mass and increases response time. The Rubikore 2’s 1.2 inch (29mm) dome eliminates this to reduce mass. The Rubikore 2 is the only member of the Rubikore family that does not pair the dome tweeter with a ribbon device, but given that the quoted upper frequency roll off is 26kHz (or much higher than human hearing actually goes), this is unlikely to be a major issue.

The crossover for the two drivers switches between them at 2.8kHz (relatively high by the standards of many competitors) and is quite unusual in 2024 terms because it supports biwiring if desired. Sensitivity is 87dB/w, which is typical for speakers at this price point, but it is achieved at a slightly trickier 4 ohm impedance, indicating that this isn’t a particularly difficult speaker to drive but does require some power to perform well. The cabinet that houses everything is a fairly standard design made of MDF sections; however, the front and back panels have a gentle curve to them, which is quite unusual.

3.Q Acoustics M20 HD

Last update on 2025-03-14 / Affiliate links/images from Amazon.

The Q Acoustics M20 HD speakers are a good value and a solid choice if you want to improve the audio on your TV but don’t want to use a soundbar. It’s definitely more versatile. They’re a pair of powered bookshelf speakers, one of which includes a digital amplifier, that provide an easy-to-use and impressive-sounding audio solution for a living room, games room, bedroom, or even a home office.

One disadvantage is that they are not ‘wireless’ in the sense you might expect. The M20 HD system includes Bluetooth streaming, but it also requires extensive cabling. The box includes a mains cable for the active speaker as well as a four-meter speaker cable with binding posts on the reverse for connecting the active and passive speakers. The active speaker effectively powers the passive speaker.

However, this sound system is a fantastic all-rounder. As we wrote in our review, “the M20 HD is great at what it does.” We also said: “If you’re as much into music as you are TV, the system’s warm digital sound, treble detail and balanced sound delivers an ideal all-round soundstage that’s as adept with Nirvana as it is with Netflix.”

The package includes two speakers: one active (with a digital amplifier) and one passive. Both are 279 x 170 x 296mm, with the active speaker weighing 5.5kg and the passive speaker 5.1kg.

Both have a 2.2cm tweeter and a 12.5cm mid/bass driver, as well as a bass reflex port in the back that disperses low-frequency sound when placed away from a wall. However, if you intend to use the M20 HD on a bookshelf with little or no space between them and the wall, Q Acoustics provides a couple of foam muffles in the box to insert into the bass reflex ports to dampen any distorted bass.

Although these powered loudspeakers can be placed anywhere, including a bookshelf, desk, or TV table, they are 11 inches/285mm deep, which may not always be convenient.

Q Acoustics refers to the M20 HD as wireless, but this only applies to Bluetooth streaming. Aside from that, the M20 HD system requires a significant amount of cabling. The box includes a mains cable for the active speaker as well as a four-meter speaker cable with binding posts on the reverse for connecting the active and passive speakers. The active speaker effectively powers the passive speaker.

There are several connections on the rear of the active speaker. There’s an optical audio input, a pair of left and right stereo audio analogue inputs, and an auxiliary 3.5mm stereo jack for connecting to a TV, Blu-ray player, set-top box, record player, or AV amplifier.

A USB-B port on the back of the active speaker allows for high-speed data transfer when connected to a PC. Cue 24bit/192kHz high-resolution music from a PC via USB, which is also available over optical audio. However, it would have been nice to see such a unique cable included in the box, as few people will have one.

There’s also an analogue input for attaching a separate subwoofer, although we’re not convinced the M20 HD needs one, particularly if you intend to feed it a diet of TV, music and gaming.

The good news is that the two speakers in the package – as mentioned, one active that needs to be attached to the mains, and the other passive, which doesn’t – can act as left or right. There’s a switch on the rear of the active speaker to determine whether it acts as the left or right channel. That makes placement far easier, since you can have an active speaker close to whatever power outlet is most convenient. It isn’t a feature we’ve seen before on similar products. 

4.KEF LSX II LT

Last update on 2025-03-14 / Affiliate links/images from Amazon.

Looking for an excellent pair of stereo speakers that received a rare 5 out of 5 stars in our recent testing? Meet KEF’s latest speakers, the KEF LSX II LT. The brand has long been at the forefront of packing what is essentially an entire hi-fi system into a pair of speakers, and it has done so again with added style.

The KEF LSX II LT features a high-quality streaming sound system housed in two very compact and attractive loudspeakers. They’re beautifully designed and can produce excellent high-resolution digital audio from any high-resolution source you feed them, including your television.

One of their appeals for smaller homes is their compact size. This means they won’t be able to fill larger rooms with sound, but that’s not their intended use. Furthermore, there are no analog inputs, which some people may miss, despite the fact that the KEF LSX II does. And they’re not the best choice for vinyl; the Kanto Ren in this guide are a better option.

If these minor issues don’t bother you, there’s little to complain about here. The KEF LSX II LT are some of the best wireless stereo speakers we’ve tested, and they won’t disappoint.KEF’s distinctive Uni-Q speaker driver arrangement is now in its 12th generation at the higher end of its model range. However, the LSX II LT uses the same 11th generation unit as the larger KEF LSX II. This means that a 19mm aluminium dome tweeter is placed in the center of a 115mm magnesium/aluminum mid/bass driver, precisely positioning the acoustic center of each unit in order to provide optimal time alignment. Each tweeter receives 30 watts of Class D power, while each mid/bass driver receives 70 watts, resulting in a claimed frequency response of 54Hz to 28kHz.

Each pair of LSX II LT speakers contains a hierarchy of units. The primary unit includes dual-band Wi-Fi and Bluetooth 5.0 with support for SBC and AAC codecs, as well as an Ethernet input, an HDMI ARC socket, digital optical and USB-C inputs, a subwoofer pre-out, and a power connection. Apple AirPlay 2, Chromecast, Spotify Connect, TIDAL Connect, and UPnP devices are all supported, and the KEF Connect control app can also play Amazon Music, Deezer, Qobuz, and internet radio.

The LSX II LT supports a wide range of digital audio file formats, including file resolutions of up to 24bit/384kHz via a network connection. The USB-C and digital optical inputs are capable of handling 24bit/96kHz content, while the HDMI ARC is limited to 16bit/48kHz. KEF’s’music integrity engine’ signal processing algorithms analyze incoming audio data before resampling to 24bit/96kHz resolution.

This is a fairly comprehensive list of features for a product of this type, but I can’t help but wish for one or two analogue inputs. Record players are popular again, and having a wired connection could be beneficial. However, they are compatible with a Bluetooth turntable.

5.Ruark MR1 MkII

Last update on 2025-03-14 / Affiliate links/images from Amazon.

If we’re going to cut to the chase (which is what this guide is about), the Ruark MR1 MkII is basically all gain and no pain. It’s small enough to fit comfortably on any remotely tidy desk, built and finished to a standard that belies its relatively low asking price (so pride of ownership is virtually guaranteed), and it sounds very accomplished.

You get aptX Bluetooth support here, and don’t let the Ruark’s small size fool you; the MR1 MkII is all business. It sounds fuller, more open, and more convincing than seems possible. Given a fighting chance with some digital audio via Bluetooth or optical, the Ruark produces an open, quite spacious soundstage with plenty of detail and a very agreeable sense of clarity in its overall presentation.

‘Musical’ may appear to be a redundant term when describing a pair of speakers playing music, but there are some alternatives that do not sound as musical as the MR1 MkII – it’s a revealing, confident, and entertaining listening experience.

There’s a clear hierarchy here. Both speakers have a 20mm silk dome tweeter above a 75mm polypropylene mid/bass driver, as well as a bass reflex port at the bottom of the cabinet, but the right-hand speaker takes over after that.

This is the speaker that the MR1 MkII uses for amplification. There’s a total of 20 watts (which is nothing special), and it’s Class A/B (which it most certainly is) – almost every alternative to the Ruark uses Class D amplification, and the use of Class A/B here indicates that Ruark takes sound quality very seriously.

In addition, the right-hand speaker handles all physical and wireless connectivity. It uses Bluetooth 5.0 for wireless streaming and supports SBC, AAC, and aptX codecs. Physical inputs include a 3.5mm analogue socket and a digital optical socket; not only does the digital input allow the MR1 MkII to function as speakers for your TV (as long as it has an optical output, of course), but it can also handle digital audio files up to 24bit/192kHz resolution. Ruark is a high-resolution system. Unfortunately, USB is the only major connection we really miss here, though it would be nice if it supported Wi-Fi, Apple AirPlay 2, and Chromecast, of course.

On the back of the cabinet, there is a subwoofer pre-out, a power connection, and an output for the braided cable that comes with the speakers to connect the right and left speakers. If you do not make that connection, the Ruark will automatically switch to single-speaker mono mode. And if you want to take your single MR1 MkII speaker with you, there’s an optional ‘backpack’ battery that attaches to the back of the speaker cabinet and should provide about 12 hours of playback as long as you don’t turn up the volume – but that’s a separate purchase.

The circular turn-and-click dial that has appeared on numerous Ruark products makes an appearance here, which is welcome because it is a useful and actually quite satisfying way to control the MR1 MkII. A single press activates the system, and Bluetooth pairing begins immediately; subsequent presses allow you to scroll through your input options; a long press turns the system off again. Of course, turning the dial adjusts the volume.

Of course, if you’re streaming music via Bluetooth, you can control it using your smartphone and/or the control app for your music streaming service. Nonetheless, Ruark offers a small, slim remote control of the clicky variety that covers all bases.

Of course, the right-hand speaker must be reasonably close to power, and the speakers cannot be separated by more than the 2m length of the cable that connects them. That will be sufficient for the vast majority of people, but it will be a constraint for some, making it one of the few potential drawbacks here.

Best stereo speakers FAQ

How we test the best stereo speakers

In testing these hi-fi speakers, we compared each stereo set at a comparable power level and tested the same tunes, plucked from a variety of music genres.

Our test songs spanned the dynamic range of music and artists, from John Mayer to Tom Petty, and from U.K. prog-metal band TesseracT to the likes of John Williams and Hans Zimmer. Each song was chosen to test the dynamics offered by each set of speakers with some speakers reacting better to certain genre’s than others, depending on their design.

Of course, not all speakers have equal function. The Q Acoustics M40 HD towers, for example, are clearly designed to cover a wider frequency range than, say, Edifier bookshelf speakers with a 4-inch woofer. We tested these speakers using our best judgement based on their individual purpose and affordability, and graded them accordingly.

Because comparing bookshelf speakers to high-performance towers is a clear case of apples and oranges, we attempt to distinguish which speaker is an apple and which is an orange.

What are stereo speakers?

Stereo speakers play sound from two separate audio channels: left and right. This allows you to hear instruments as if they were coming from different locations, so a guitar might sound like it’s coming from the far left of the room, whereas a vocal sounds like it’s coming from the center.

The difference between stereo and mono speakers, where each speaker receives the same audio, is dramatic. It makes music, in particular, sound much larger and more detailed, and when watching television, the sound appears to come from both sides of the room.

Can a single speaker be stereo?

Yes, you can. In fact, some single speakers can deliver 360-degree audio. That’s because inside the case there are multiple speaker drivers, which are the vibrating domes you probably think of when you hear the word “speaker”. If a speaker has more than one set of drivers inside it, it can be configured so that one driver plays sound from the left audio channel and another plays the sound from the right audio channel.

The problem with that is that the drivers are still very close together, and that means you don’t get the impression of room-filling sound that you get from standard stereo speaker pairs.

There are some quite clever ways to get around this – some phones and tablets use clever audio processing to make their audio sound much wider than you’d expect from such small devices – but ultimately there’s only so much you can do when your speaker drivers are right next to each other. We much prefer the sound of dedicated, separate stereo speakers and we’re sure you will too.
