The AIO 3 houses four speakers arranged in a stereo configuration, powered by a total amplification of 90 watts. Connectivity is comprehensive: Wi-Fi, Bluetooth aptX, optical and analog physical inputs, not to mention a multiroom system supporting up to 12 devices. The dedicated app centralizes access to major streaming services and enables playback of high-resolution files up to 24-bit/192 kHz.
The speaker adopts a compact rectangular format of 36 × 19.5 × 15 centimeters for a weight of 5.1 kilograms. This mass comes from the high-density wood cabinet, a preferred material for its acoustic properties. Wood provides the necessary inertia to contain speaker vibrations and limit parasitic resonances.
The brushed aluminum base and top create a contrast with the acoustic fabric that wraps the rest of the cabinet. Triangle offers seven textile finishes: Camel, Sage Green, Greige, Blue, Black, Forest Green and Ochre Red. The aluminum feet incorporate rubber pads to minimize vibration transmission.
Controls are limited to four discreet buttons on the front panel. A single LED indicates the active source through a color code: white for Wi-Fi or USB, green for auxiliary, orange for optical, blue for Bluetooth. A bass-reflex port on the rear panel reinforces the bass. Connectivity includes: S/PDIF optical input, 3.5 mm mini-jack, USB 3.0 port, RJ45 10/100M LAN Ethernet socket and two buttons for pairing and reset.
The AIO 3 houses four speakers: two 25-millimeter fabric dome tweeters and two 10-centimeter mid-bass drivers. The assembly is split into two complete stereo channels, each combining a tweeter and a mid-bass driver to reproduce the left and right channels respectively. This physical separation aims to create a true stereo image.
The amplification delivers 45 watts RMS per channel at 8 ohms, totaling 90 watts. This power enables sound coverage for rooms up to 20 square meters. The filtering bears Triangle’s signature: a clear and detailed midrange, present highs without harshness, controlled bass. This approach favors vocal intelligibility and instrument clarity, prioritizing musicality over brute force demonstration.
The AIO 3 integrates a Wi-Fi receiver and an RJ45 10/100M LAN Ethernet port for network connection, with support for UPnP and DLNA protocols. Bluetooth 4.2 with aptX codec ensures transmission without noticeable loss from mobile devices.
The S/PDIF optical input accepts a digital signal from a television or game console. The 3.5-millimeter mini-jack offers a universal analog connection. The USB 3.0 port enables direct playback from a flash drive or hard drive, and powers devices up to 5 volts and 1 ampere maximum.
The speaker decodes MP3, AAC (all variants), FLAC, WAV, APE and Apple Lossless. High-resolution playback reaches 24-bit at 192 kHz, far exceeding standard CD quality.
The Triangle AIO app, available on iOS and Android, centralizes control. Configuration is performed by pressing the Connect button on the rear, with the speaker switching to Wi-Fi access point mode to receive home network credentials.
The app directly integrates Spotify, Deezer, Qobuz, Tidal, Napster, Amazon Music and TuneIn for Internet radio. The multiroom system supports up to twelve devices, with the ability to form a true stereo pair or a group mode to broadcast the same music everywhere.
Settings include an alarm function, programmable sleep mode and favorite presets. An infrared remote control accompanies the speaker with essential commands and bass and treble tone adjustment buttons, absent from the app.
Yes, the Triangle AIO app allows two speakers to be configured in true stereo mode. Each AIO 3 then reproduces a complete channel (left or right) instead of operating in integrated stereo single-unit mode. This configuration offers more pronounced channel separation and a wider soundstage, ideal for a fixed installation in a listening room.
The AIO 3 plays MP3 files (CBR and VBR), AAC and its variants (AAC-LC, HE-AAC, HE-AAC v2), as well as lossless formats APE, FLAC, WAV and Apple Lossless (ALAC). High-resolution playback reaches 24-bit at 192 kHz via the local network and USB 3.0 port. This capability ensures faithful reproduction of demanding recordings.
Triangle recommends the AIO 3 for rooms up to 20 square meters. This area suits most bedrooms, offices and kitchens. The 90-watt power enables high sound levels without distortion. The rear bass-reflex port benefits from being at least 20 centimeters away from a wall to avoid bass overload and achieve optimal balance.

Pairs perfectly with an AIO Twin to add sonic depth, but be sure to adjust the equalizer (no 3D for me!) and the placement of the 3 speakers.

Very good manufacturing quality. In terms of sound and usage, it is also an excellent product capable of providing sound for a 45m2 space without any issues. Pleasant sound rendering with present bass, midrange, and treble. Melodious, dynamic sound that never fatigues the listener.
Ability to adjust treble and bass directly on the speaker, via remote control, or via app.
