Imagine bookshelf speakers that sound as if they were created not by engineers, but by singers. That's exactly the impression made by the Triangle AIO Twin active acoustic systems. The French brand is renowned for its musical, lively sound, and this philosophy is fully revealed in these compact speakers.
Their secret lies not in dry technical specifications, but in a special approach. Triangle's engineers seem to have thought first and foremost about how to convey the emotion and naturalness of a voice or violin. The result is not an analytical sound, but a surprisingly engaging one that you want to listen to for hours.
This is a self-contained solution: there are already amplifiers and a DAC inside, so all you need is a signal source. They are designed to let you forget about the technology and just enjoy the music. Let's take a look at what is so special about these modern “sirens.”
Minimalist futurism
I also make no secret of the fact that I love unusual colors. And we live in a world where beige speakers in futuristic interiors from 1970s magazines seem unusual. Of course, this shade has an advantage — it is so nondescript that it will fit into almost any modern minimalist interior except for monochrome gray tones. And most importantly, you can't see dust on it. At all.
In addition to the beige finish, there is also a beautiful dark blue, deep as the ocean, as well as standard black and white, and even walnut veneer. And in collaboration with Pro-Ject, a handful of turntables in the same colors have also been released.
The matte, slightly rough body adds to the futuristic look, with no gaps on the edges and a monolithic appearance. It is solid, responds softly and neatly to a knock, and stands on wide cylindrical legs topped with rubber bands around the edges. The legs are old gold in color, and the inscription on the body matches them.
The tweeter is surrounded by a cool bronze-colored ring and a small black sound guide with concentric notches. The tweeter itself is an inch-long, with a soft silk dome and a rounded suspension.
Underneath it is a 13 cm midrange/woofer driver, concave with a beautiful smooth cup — without any phase-aligning pulleys or dust covers. It is hidden deep enough in the body, suspended on a rubber mount and decorated with a black plastic ring. There are no visible screws or other fasteners, which adds to the monolithic feel of the design. Even the protective grilles are magnetic — there are no holes for pins.
Despite their unusual but somewhat dull color scheme, the speakers are stylish. All these small details — the non-standard legs, the solid-looking body, the ring around the tweeter — come together to form an organic, harmonious whole that is beautiful in its aesthetic geometric precision. However, the model's appearance is borrowed from the long-produced passive LN01.
Let's all be friends
One of the most common types of active speakers is the “master-slave” pair, where all the electronics are located in one speaker, and the second is attached to it with a passive second channel. This is precisely how the AIO Twin is assembled: the right channel is active, and the left is passive. Because of this, the front panel of the right speaker is decorated with two circles: one hides an IR signal receiver from the remote control, and the other hides a multicolored LED.
And this LED is impossibly bright and glows in unusual acid colors. It shows which input is currently active. Bright pink, almost fuchsia, is optics. Nuclear green is RCA. Lemon yellow is AUX. Azure blue, like the dragons in Heroes of Might and Magic, is Bluetooth. Blood red is standby mode. The calmest color, a delicate lilac-white, is for the network connection.
In my opinion, this LED indicator rivals the brightness of an OLED TV playing a modern blockbuster in the dark and is very distracting: you feel as if you are under the watchful eye of some kind of Terminator.
But the best part is that there is a button on the remote labeled “Dimmer.” The icon on it is a speaker with a cross through it, which makes it seem as if the French messed up the English localization and mistranslated “Mute.”
In fact, pressing and holding this button turns off the frighteningly bright LED, and it only lights up again when switching inputs, and then goes out again. So, if you want, you can easily put these compact shelves in your bedroom — the light bulb won't bother you.
By the way, the remote control is simple but sturdy. It is made of fairly strong plastic, with large rubber buttons that are easy to press. In addition to the combined mute and LED off button, there is a power button, a round section with playback and volume controls, a reset button, an input selector switch, and two pairs of tone control buttons. The remote is powered by a CR2032 battery, which is included in the package.
The rear panel of the slave speaker is decorated with only a pair of screw terminals on a plate under the phase inverter, but the master speaker is much more interesting. There are a sea of connectors: optical, RCA with a switch between line and phono, USB for connecting a flash drive and hard drive, 3.5 mm AUX, Ethernet, and a subwoofer output.
Overall, the connectivity is very good — the AIO Twin can be paired with absolutely any system. I wouldn't mind having a USB B port for connecting to a computer and HDMI ARC, but space on the rear panel is limited.
One of the main features of the AIO Twin is its network and multi-room functionality. Connecting to the network is very simple—you can either plug in a cable or use Wi-Fi. Just press the “Connect” button on the back panel and follow the instructions in the TriangleAIO app.
There is only one minor drawback: if the speakers are turned off and then turned back on, they will not start working until they reconnect to Wi-Fi, even if you plan to listen to them via optical connection. And sometimes the Wi-Fi search can take a minute or two — but this is most likely a feature of my home network, and the process is probably faster on other systems.
Also, AIO Twin does not remember the login that was used before shutdown and automatically switches to network mode when restarted. Apparently, the system is configured to be in standby mode at all times, which is why it behaves this way.
The speakers themselves are ready to connect to streaming services — Tidal, Deezer, Spotify, Qobuz, TuneIn, and several local services are available. Streaming is controlled from the app — its interface is exactly the same as that of the app for Audio Pro devices, for example. This is beneficial because it is convenient, straightforward, and easy to understand.
In addition to streaming services, you can select any other input in the app: line, RCA, Bluetooth, optical, or USB. There is also the option to connect to shared folders on your home network. But in my case, Triangle refused to load all the content: the app only showed the first 40-50 items from my entire music library — whether I browsed by folder, artist, or album — which is not enough even for my small collection. Again, this may be due to the peculiarities of my network.
Moreover, in some folders, files were not displayed at all, but the same files opened perfectly when moved to other folders. By the way, the speakers recognize and even play MQA files — apparently by unpacking them into FLAC.
It turns out that the Triangle AIO should be considered primarily as a system for working with streaming services and cable-connected sources. It has some minor issues with home servers.
A test drive of the Triangle AIO Twin active bookshelf speakers showed that this is a rare case where style, simplicity, and sound quality really do go hand in hand. Despite their compact size, they sound powerful and voluminous, with clear highs, rich mids, and noticeable but not overloaded bass. Controlled via Bluetooth, Wi-Fi, or an app, they support major streaming services and can be set up even by a novice. The main surprise is in the brand's signature “airiness” of sound, which Triangle engineers seem to have truly inherited from sirens: the music envelops you without overwhelming you, appealing to your emotions.
Under the spell
I used most of the available connection options: TV via optical cable, laptop connected via UPnP, streaming services Tidal, Spotify, and Deezer, as well as Bluetooth and USB flash drives. I should mention right away that the speakers clearly show the difference in sound between Spotify and Deezer with Tidal. The former sounds a little more bloated, muffled, and flat, while the latter has more air, detail, and a pleasant naturalness. In general, this is as it should be. And the difference is audible, even when connected via Bluetooth and playing music from these services on a smartphone. LDAC would be a nice addition, of course, for complete bass-heavy bliss…
These are small Class D speakers with 50 watts per channel, and they play in keeping with the character of Triangle equipment — lively, bright, beautiful, and festive. And how they deliver vocals! 80% of the music I prefer is instrumental, but with the AIO Twin, I delved into the deepest recesses of my tastes, searching for melodies with a wide variety of voices just to see how the speakers would handle them.
The spectrum was quite broad: from delicate female voices like Sally Shapiro and early ballad Madonna to the deep, dramatic Peter Steele, from Corey Taylor in all his variations and Trent Reznor to the shamanic neo-folk in the format of Udmurt techno-chastushki from Post-Duke, from the over-the-top Cradle of Filth with Sopor Aeternus to the ingratiating, sighing drum ‘n’ bass, from Prince to Bocelli, from the Pet Shop Boys to Nightwish…
Something is clearly being added to the AIO Twin's vocals — a little extra volume, as if there were a little more air in the middle thanks to a barely noticeable reverb. And with that comes mass, texture, liveliness, and richness.
It cannot be said that the acoustics focus specifically on the vocals and put them first — there is no such bias, the vocals do not stand out, pushing the other ranges into the background. But they do attract attention.
The speakers keep the rhythm well—neither the electronic drumming nor the infernal gent presented any technical problems for the AIO Twin. Emotionally, however, things are not so simple. While the lively psychedelia somehow fit into the acoustic presentation, the low-tuned guitars sounded a bit out of place — like cabaret at a funeral.
There are two reasons for this: the tiny speakers simply lacked the power and size to accurately convey all the severity, massiveness, and inevitability of thick strings, and the positive character of Triangle was fully embodied in the AIO Twin.
With Tidal, there were sometimes too many high frequencies, especially given the location of the speakers — a meter and a half from the wall on each side and even more from the front. If you move them closer to the back wall, the balance evens out: the bass becomes more noticeable and takes on some of the brightness of the treble.
The AIO Twin navigated industrial noise with surprising ease. They don't provide perfect holography, where you can reach out and touch every individual rustle, but they give the cacophonous mince enough texture and substance to avoid confusion.
They are suitable for background listening, thoughtful listening, and loud listening — depending on your mood and the source. However, at very high volumes, they start to whistle. By the way, here's a funny thing: Triangle has three separate volume controls — on the remote, on the speakers themselves, and in the app. Changing the volume from the remote or the speakers themselves does not change the volume in the app, and vice versa.
So, what did we end up with? Triangle AIO Twin is not just another pair of speakers. They can be safely called a complete sound center, which has been cleverly packed into compact active bookshelf enclosures. The main credit here, of course, goes to the subwoofer, which is responsible for the entire lower part of the range.
It is the subwoofer that transforms the light and detailed sound of the bookshelf speakers themselves into a full-bodied, rich, and deep picture. The bass is not just “there” — it is clearly defined, fast, and does not blur the other frequencies. The bass does not dominate, but complements, creating the very foundation that small active speakers so often lack.
All in all, for its price and format, this is a very competent and balanced set. It is suitable for those who want high-quality, powerful sound for a medium-sized room without unnecessary wires and complicated settings. If you are looking for compact yet capable speakers, the Triangle AIO Twin is definitely worth your attention.
