Dali Rubikore 2 review: excellent value for money in these big-sound, small-size stereo speakers
A longstanding concept in hi-fi (and indeed many other product categories) is that of 'trickle down.' The idea is simple enough; technology and design ideas that first appear in the flagship products is gradually made available at more terrestrial levels as time goes on. It's a very important dynamic because, while many people will move upward through a product range as time goes on, rather fewer of them will make it all the way to the top. Bringing flagship technology down to a level more people can access is very important – and many of the best stereo speakers we've tested have been able to do just that.
The Dali Rubikore range is a physical manifestation of the trickle down concept, indeed the ideal is so important to the their existence it is reflected in the name. The replacement for the long running and highly regarded Rubikon series of speakers and some of the advancements are derived from the Kore (stylised to 'KORE') technology that first saw use in the Kore floorstander which is yours for a brisk $110,000 / £85,000. The resulting speakers have their name revised to reflect this and are now the Rubikore range of which the Rubikore 2 is the only standmount model.
The Rubikore 2 pitches in at $4,000 or a little over £2,000; a key price point for standmount speakers and one which is contested by a very large number of companies. To stand out from the pack, the Dali will need to be very good indeed. The omens are good; The Kore technology is used to improve some already very capable drivers, the claimed measurements look excellent and the range has some up to date thinking in terms of multichannel as well as having some very attractive finishes. Does this on paper ability translate to real world greatness?
The Rubikore range debuted in May 2024 with the wraps being taken off at the High End Show in Munich . The range comprises a pair of floortanding models, the standmount seen here, an LCR (a speaker engineered to be both a centre speaker and also operate as a stereo pair) and an on wall speaker. This range spans from £1,200 for the Rubikore On Wall to £6,000 for the Epikore 8. This is a fair amount of money but rather less than what Dali is asking for the Kore.
The Rubikore 2 is available in the UK for £2,200. It is $4,000 in the USA and $4,200 in Australia. This price does not include a stand and neither does Dali make a dedicated version for the Rubikore 2. In a large number of the stock images, you'll see the Rubikore 2 sat on stout bits of furniture which will work up to a point but you should budget for a pair of stands to get the best from them. I used a hefty if cosmetically unspectacular Custom Design stands throughout for testing. One positive attribute is that all four finishes have the same price, with none commanding a price premium.
Dali Rubikore 2 review: SpecsDali Rubikore 2 review: FeaturesAs a passive speaker, the Dali is not as sophisticated as powered and active designs but, given it's a relatively small speaker made out of fairly well established materials, there is a surprising amount going on inside them. Dali has used the enormous amount of data gained the development of the Kore speaker to improve the Rubikore models. Obviously, there are many parts of a $110,000 speaker that don't make it down to this level, but a number of 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 is helped by a rear firing bass port that employs a continuous flare along its length (that is to say it isn't the same diameter along its length). This helps to keep the flow of air out of the port quieter as the diameter increases as the air accelerates allowing it to expand. This port helps the Rubikore 2 to reach down to 50Hz at a +/-3dB measurement – a usefully demanding way of measuring this.
This mid bass driver is partnered with a soft dome tweeter that is built around the principles of reducing mass; a very desirable attribute in a high frequency driver. Traditionally, tweeters used a substance called ferrofluid to cool them but this adds mass and increases the response time. The Rubikore 2's 1.2 inch (29mm) dome does without this to reduce the mass. The Rubikore 2 is the only member of the Rubikore family to not partner the dome tweeter with a ribbon device although given that the quoted upper frequency roll off is 26kHz (or, quite a bit higher than human hearing actually goes), this is unlikely to be a huge issue.
The crossover for the two drivers hands over between them at 2.8kHz (relatively high by the standards of many rivals) and is quite unusual in 2024 terms because it supports biwring should you wish. Sensitivity is in keeping with most things at the price at 87dB/w but this is achieved at a slightly trickier 4 ohm impedance which means this isn't a truly difficult speaker to drive but needs a little power to do its best work. The cabinet that houses everything is a relatively conventional type made of MDF sections; although something that is quite unusual is that both the front and rear panels have a gentle curve to them. The cabinets are extensively braced and substantial things though and the whole speaker feels usefully solid.
Placed on stands with absolutely no toe in applied (Dali is adamant that its speakers should point dead ahead), the Rubikore 2 doesn't need vary long to start to impress. The first and most immediately noticeable aspect of the performance is the bass extension and the scale that goes with it. The Dali gives Ben Howard's Every Kingdom a weight and authority that makes the performance utterly convincing. This album is not a bass monster but plucked bass notes and the sparse percussion it possesses are given a weight you feel as well as hear and the effect this has on the believability of the track is considerable.
Tonally, the Rubikore 2 is a class act. Across standard challenges like voices, violins, cellos and pianos, it has managed to sound consistently right. This is not a showy or attention grabbing speaker. It doesn't go in for the sort of emphasis on parts of the frequency response that is superficially impressive but that becomes wearying after a while. Instead it presents a frequency response that feels even and consistent and allows the music to generate its own emphasis. The astonishing Emily King track Forgiveness on her Scenery album is presented with King being the absolute focus of your attention. Everything else that should there is there but it's subsumed by what the recording regards as the important part and the Dali following those instructions perfectly.
Something else that is very welcome is that the when the quality of the material being played drops, the Dali still maintains a level of realism and overall quality that is extremely impressive. A blast through Greta van Fleet's Anthem of a Peaceful Army delivers a healthy dose of the 'I can't believe it's not Led Zeppelin' sound without drawing too much attention to the limitations of the mastering as a whole. Instead the Rubikore does a fine job of making things sound usefully exciting and energetic, with a very pleasing level of get up and go to its overall performance.
So far so good, but there are some areas where the Rubikore 2 is less effortlessly composed. It had the misfortune of following Tannoy's odd but immensely talented Autograph Mini through testing and while it convincingly beats the Tannoy in terms of bass extension, it simply doesn't create the same almost three dimensional soundstage of the material being played. Some of this is a bit of a puzzle because viewed objectively, the Dali isn't doing anything wrong. The handover between the mid bass and tweeter is seamless and there is no real perception of congestion to the sound, even when very complex material is being played. Nevertheless, the Dali tends to produce a sound that sits between the two speakers rather than extends beyond it.
There is also an element of the Dali's performance that might be a benefit or a negative depending on your listening situation. For what is a relatively compact device, the Rubikore 2 is capable of playing impressively loud and sounding effortless while it does so. Even rivals that boast a similar driver complement can struggle to match the way that the Dali handles the huge crescendo of Public Service Broadcasting's Broadcasting House. Without sounding strained or pushing the limits of the cabinet, the Dali simply keeps hitting hard and sounding utterly composed while it does so. The caveat to this is that at lower levels, the Rubikore 2 sounds a bit on the safe side. If you don't have the scope to open the taps every now and again, some of the abilities of the Dali will be less easy to enjoy.
When you do give them a bit of level though, the Dali is consistently good fun. This isn't simply fun in the 'play fast music and nod your head' ideal but an ability to get to the crux of the emotional content of the material being played. It's the difference between listening to My Baby's Tribulations and thinking, 'that's a nice song' and sitting there rapt at one of the most stunning vocal arrangements I've had the pleasure of listening to.
Dali is a Danish brand and while I'm not sure that some sort of official document exists to the effect that no Danish brand is allowed to make unattractive equipment, it does seem to be a rule they all work to. The Rubikore 2 is elegantly proportioned, with a pleasing ratio to the width and depth that is balanced by the size of the drivers contained within it. There are four finish options, including two wood veneers that have been chosen to complement both the proportions and the drivers very well. Even the white of the review samples; a finish I'm not traditionally enthused about, looks good against the contrast provided by various sections of the speakers.
This effect is enhanced by just how well made and finished the Dali is. These aren't cheap speakers but even so, the care that has gone into how they have been assembled and finished is impressive. About the only thing I can really say against them is that, where the vast majority of rivals use magnetic tabs for the grilles, the Dali still uses lugs. They've cleverly used screw fittings to hide some of the holes but there is still a visible one above the tweeter which looks a little unsightly.
As noted a few times so far, $4,000 is not the sort of figure that most of us lose down the back of the couch, but it's hard to argue with the feel or quality of the Rubikore 2 for this money. This is a brilliantly made and finished speaker that is built in Europe and comes with a five year warranty. It does a fine job of avoiding the nagging feeling of buyer's remorse when you unbox them which is no bad thing. They will require decent quality equipment to partner them but not to the extent where they won't improve an existing system of slightly less expensive electronics, so long as there is sufficient power to drive them.
The curious but lovely Tannoy Autograph Mini is the same price as the Dali. The product under review here completely demolished it in terms of bass extension and scale, but the stereo image it can produce is something that the Dali cannot match. The Monitor Audio Studio 89 is slightly less money but comes laden with technology and striking looks as well as an ability to resolve fine detail that very little near the price gets anywhere near. Outside of speakers we have looked at, Bowers & Wilkins, Neat and PMC are all formidable contenders at this price point and will keep the Dali honest.
How I tested the Dali Rubikore 2The Dalis were placed on a pair of Custom Design stands and run in a system built around a Naim Supernait 3 integrated amp; a slightly more expensive device than the Dali but able to deliver plenty of power and show what the Rubikore 2 was doing at any given time.
Source equipment took the form of an Eversolo DMP-A8 streamer. This formidable digital front end offers superb UPnP streaming but also has an HDMI ARC connection allowing an LG OLED to be connected and routed through the system to the Dali. I tend to use the Eversolo via the Roon software platform because I control most things through that and tend to prefer it.
I also made use of not one but two turntables under testing. The first is a resident Rega Planar 10 using the company's newly released Nd7 moving magnet cartridge. The second was the newly released Pro-Ject Debut Evo 2 for which the Dali acted as a test speaker. Both turntables used a Cyrus Classic Phono for the phono stage. Material used has been a variety of styles and genres via The test material has been FLAC, AIFF, Tidal, Qobuz and Spotify as well as some vinyl.
