KEF Coda W: Two-minute review
KEF, it seems, has identified a customer for whom its existing lineup of wireless stereo speaker systems is not absolutely perfect. This customer can live without network streaming, but would like to be able to listen to a turntable. They don’t need their system to work on a desktop, but they would like it to be available in a fairly wide choice of finishes. And so here’s the Coda W.
As well as the network streaming/phono stage trade-off and the ‘regular’ size of the cabinets compared to the dinky dimensions of some predecessors, the Coda W has cutting-edge Bluetooth connectivity (the aptX Lossless codec is supported), an HDMI eARC input and properly hi-res functionality via its digital optical and USB-C inputs. Four discreet modules of Class D amplification power the 12th generation of the company’s Uni-Q driver array – 30 watts goes to each 25mm aluminium dome tweeter, 70 watts to each 130mm magnesium/aluminum mid/bass driver. And if that all sounds a bit tentative, there’s a pre-out for a subwoofer too.
In practice, it works either ‘pretty well’ or ‘very well indeed’, albeit maybe not quite well enough to sit among the best stereo speakers on the market. The phono stage is probably the least effective of the input options, which is a pity, when you consider it’s one of the real differentiators between this system and the slightly more expensive KEF LSX II LT, its most obvious stablemate. If, however, you switch to one of the digital inputs (either wired or wireless) and the Coda W has plenty going for it. There’s detail and drive, plenty of well-behaved low-frequency presence, a really even-handed attitude towards tonality and frequency response, and a level of energy and engagement that’s a match for the best that any even remotely price-comparable rival can muster.
Turn the volume down to the sort of level that conversation can easily be heard over, though, and quite a lot of this attitude is replaced by a more pedestrian, less energetic character that sucks some of the animation out of recordings. Mind you, if you want to listen at low levels in order to engage in conversation, it could be argued that this isn’t all that much of an issue.
KEF Coda W review: Price & release date
- $999 / £799 / AU$1449
- Released in October 2025
The KEF Coda W wireless active stereo speaker system is on sale now, and in the United States it costs $999. The asking price in the United Kingdom is £799, while in Australia it goes for AU$1449.
There are a few very credible alternatives around, of course, not least from KEF itself in the shape of its slightly smaller, slightly pricier, slightly differently specified LSX II LT wireless stereo speaker system. So does the Coda W have what it takes to, um, undermine its sibling and cannibalize its sales?
KEF Coda W review: Features
- 200 watts of Class D power
- Wireless and wired connection options
- 12th-gen Uni-Q driver array
In most respects, the Coda W is specified as extensively as seems reasonable, given the asking price. Then you consider the way its (admittedly more expensive) LSX II LT sibling is specified, and you realize you’re engaged in a game of ‘swings and roundabouts’.
Still, the gain outweighs the pain here more than a little. The Coda W is an active stereo speaker with 200 watts of Class D power available – naturally enough it’s divided half-and-half between the two speakers. Slightly unusually for an active – rather than a powered – system, is that only one speaker requires mains power. This ‘primary’ speaker connects to its ‘secondary’ partner via a supplied length of USB-C-terminated cable which transfers power as well as digital audio information.
The secondary speaker has just a USB-C input on its rear panel – it’s positioned beneath a bass reflex port that vents from higher up. The primary speaker, by way of contrast, is all action. It has a USB-C output for connection to its partner and a matching bass reflex port, of course, but in addition, the rear panel features (in no particular order): a connection for mains power and an ‘on/off’ switch, an HDMI eARC socket, a digital optical input, a USB-C slot for data transfer, a line-level stereo RCA input, a moving magnet phono input (also on stereo RCAs) with a ground post, and a pre-out for a subwoofer. There are also buttons to initiate Bluetooth pairing (the KEF uses Bluetooth 5.4 with aptX Lossless codec compatibility) and to reset the whole shebang. There’s a switch to turn the ground lift circuit on or off, too.
What’s missing? Well, there’s no Ethernet socket, and no Wi-Fi connectivity either. So network streaming is unavailable, which puts the Coda W at a disadvantage compared to the LSX II LT, although it hits back with its integrated phono stage. No network capability means no Spotify Connect, Tidal Connect etc, so if you’re using Bluetooth to enjoy some wireless tunes, it means your smartphone (or what-have-you) will be fully occupied.
The input resolution of the USB-C is 24bit/192kHz, while the digital optical is 24bit/96kHz and the HDMI eARC operates at 16bit/44.1kHz – analog signals are digitized on entry to 24bit/96kHz. All these wired sources are (re)sampled to 24bit/96kHz before being decoded to the analog domain the driver arrays can understand.
Unlike the LSX II LT, which features a compact version of the 11th generation of KEF’s instantly recognizable Uni-Q driver arrangement, the Coda W is packing the 12th version. There’s a 25mm aluminum dome tweeter behind an elaborate waveguide and positioned in the throat of a 130mm magnesium/aluminum mid/bass driver. Each tweeter is in receipt of 30 watts of power, while each mid/bass driver gets 70 watts. This arrangement, reckons KEF, is good for a frequency response of 41Hz – 20kHz.
KEF Coda W review: Sound quality
- Energetic and confident sound with detail to spare
- Loses some animation at low volume levels
- Phono stage is nothing special
At its best, the KEF Coda W sounds very, very good indeed. Unlike some of its most obvious rivals, though, getting away from ‘its best’ is not especially difficult to do.
With a genuinely hi-res (24bit/96kHz) FLAC file of Prince’s U Got the Look incoming via the USB-C socket, there’s plenty to enjoy about the way the system performs. It maintains a strictly neutral tonality, adding no discernible heat to any part of the frequency range and not cooling any part of it down either. The top end attacks with crisp determination, but despite what you might have read about metal tweeters, there’s no suggestion of hardness or glassiness to the treble sounds the Coda W delivers.
The transition into the midrange is smooth to the point of inaudibility, and once there the amount of detail the KEF is able to extract and contextualize allows both the voices in the recording to come across with all their attitude (horny, mostly) and character intact. Beneath here, the lowest frequencies hit hard but control their attack well, so the four-square rhythm is expressed confidently. As with the rest of the frequency range, detail levels down here are high, with plenty of subtlety and variation to go along with the straightforward punch available.
The frequency response is even-handed, with no area underplayed or overrepresented, and the soundstage the KEF creates is big and plausible. Like all the best Prince songs, U Got the Look sounds like an expensive demo, with great big spaces and silences playing their part. The Coda W has no problem laying the stage out coherently, and it gives just as much emphasis to the absences as it does the actual occurrences. Dynamic headroom is significant, and the lower-key dynamics of harmonic variation are also paid close attention. The KEF sounds keen to entertain, and it preserves all the energy the recording wants to communicate.
All of this is true, to a lesser or greater extent, when listening to the same song wirelessly via a FiiO digital audio player running the Tidal app or to a CD-borne copy of the song delivered into the system’s digital audio input. The Coda W remains a lively, informative and quite vibrant listen that seems to revel in the vivid and upfront nature of the recording.
It’s possible to move away from this best-case scenario, though, either by turning the volume down to a modest ‘background’ sort of level or by listening to a vinyl copy of the song through the integrated moving magnet phono stage.
The differences are probably less pronounced when playing the record, so I may as well start here. The phono stage fitted to the Coda W just isn’t anything special – for all of the cliches regarding the vinyl format and its facility with rhythm and tempo-management, the song sounds just fractionally lumpy and leaden-footed when heard this way. It’s from the 80s, sure, when every rhythm was mechanical and regimented, but there was always more swing to Price than the Coda W is willing to reveal via its phono stage. The knock-on effect is a minor dialling down of the energy in the recording, and a mild loss of engagement as a result.
Turning down the volume results in a slightly more fundamental shift in emphasis. I know it’s quite easy to argue that ‘background’ levels would tend to imply that not all that much attention is being paid to the music, and certainly no critical listening is likely to be happening, but there are more than enough systems around that don’t change their sonic character at lower volumes to understand that the changes that the Coda W goes through aren’t inevitable or, to a lesser extent, excusable.
Turning the wick down means a lot of the system’s previously vivid and energetic attitude towards music goes astray, replaced by a slightly matter-of-fact and unengaged alternative that’s not especially welcome. Particularly not when you know what the system is capable of if only it were playing a little louder.
- Sound quality score: 4 / 5
KEF Coda W review: Design
- 285 x 168 x 268mm (HxWxD)
- Choice of five finishes
- Optional SQ1 stand
The Coda W may cost less than the LSX II LT, but there’s more of them. At 285 x 168 x 268mm they’re bigger than their siblings in every direction – if you were hoping to position these on a desktop, think again. Unless you have a mahoosive desk, anyway.
A pair of speaker stands is the way to go. Any decent product will do, of course, but KEF will happily sell you a pair of its SQ1 stands that have been developed with the Coda W (and a few other KEF models) in mind.
The standard of build and finish is well up to standard. The Coda W may lack the exciting curves of their LS and LSX stablemates, but they look and feel good. And the choice of five finishes – my review sample’s dark titanium, midnight blue, moss green, nickel gray and a vintage burgundy version that’s only available from very select outlets – means there really ought to be something to suit your mood and/or decor here.
KEF Coda W review: Usability & setup
- Truncated version of the KEF Connect control app
- Physical controls on the primary speaker
- Small remote control handset
KEF supplies a little remote control handset to operate the Coda W. It deals with ‘power on/off’, ‘volume up/down/mute’, allows you to cycle through the inputs and, if you’re streaming via Bluetooth, to access ‘play/pause’ and ‘skip forwards/backwards’.
The controls, with the exception of the Bluetooth stuff, are duplicated as touch-controls on the top of the primary speaker – although you can only scroll through your inputs in one direction, which is a (very) mild irritation.
There’s also a very brief version of the KEF Connect app available too. It connects via Bluetooth, offers input selection and volume control, allows you to check for updates, and also features a balance control and rudimentary EQ adjustment in the shape of ‘treble cut/boost’ and ‘bass cut/boost’ controls. It’s also where you can let the Coda W know if it has a subwoofer attached.
- Usability & setup score: 4.5 / 5
KEF Coda W review: Value
- Very high standard of build and finish
- Enjoyable sound quality…
- But it’s variable depending on the output used
It’s difficult in the extreme to suggest the KEF Coda W is anything other than very decent value for money. It has some real highlights where specification is concerned, is built and finished to a very high standard, and is capable of uncomplicatedly enjoyable sound quality too.
The fact that it lacks some features available in a very similarly priced product from the same manufacturer is, ultimately, less concerning than the fact that its sound is quite variable depending on the input you’re using.

KEF Coda W review: Also consider
How I tested the KEF Coda W
I positioned the speakers on a pair of Custom Design speaker stands, connected them together using the supplied USB-C cable and plugged the primary speaker into the mains.
Then I connected a Technics SL1300G fitted with a Goldring 1042 cartridge to the phono input (and also to the line-level input, having positioned a Cambridge Alva Duo phono stage between the two), and plugged a Rega Apollo CD player into the digital optical input.
I used an Apple iPhone 14 Pro and a FiiO M15S digital audio player as Bluetooth sources, and connected an Apple MacBook Pro (running Colibri software) to the USB-C input. After this, I put the speakers either side of my Philips 48OLED806 TV and connected them via HDMI. Lots of sources, meaning lots of content – and for quite a length of time.
