The AIO 3 houses four speakers arranged in a stereo configuration, powered by a total of 90 watts of amplification. Connectivity is comprehensive: Wi‑Fi, aptX Bluetooth, optical and analog physical inputs, plus a multiroom system supporting up to 12 devices. The dedicated app centralizes access to major streaming services and enables playback of hi‑res files up to 24‑bit/192 kHz.
The speaker adopts a compact rectangular format of 36 × 19.5 × 15 centimeters and weighs 5.1 kilograms. This mass comes from the high‑density wooden cabinet, a material favored for its acoustic properties. Wood provides the inertia needed to contain speaker vibrations and limit unwanted resonances.
The brushed aluminum base and top create a contrast with the acoustic fabric wrapping the rest of the cabinet. Triangle offers seven fabric finishes: Camel, Sage Green, Greige, Blue, Black, Forest Green, and Ocher Red. The aluminum feet incorporate rubber pads to minimize vibration transmission.
Controls are limited to four discreet buttons on the front. A single LED indicates the active source via a color code: white for Wi‑Fi or USB, green for auxiliary, orange for optical, blue for Bluetooth. A rear bass‑reflex port reinforces the low frequencies. Connectivity includes: S/PDIF optical input, 3.5 mm mini‑jack, USB 3.0 port, RJ45 10/100M LAN Ethernet jack, and two buttons for pairing and reset.
The AIO 3 houses four drivers: two 25‑millimeter fabric‑dome tweeters and two 10‑centimeter mid‑bass units. The system is split into two complete stereo ways, each combining a tweeter and a mid‑bass to reproduce the left and right channels respectively. This physical separation aims to create a true stereo image.
Amplification delivers 45 watts RMS per channel into 8 ohms, for a total of 90 watts. This power can fill rooms up to 20 square meters. The crossover bears Triangle’s signature: a clear, detailed midrange, present but non‑aggressive highs, and controlled bass. This approach promotes vocal intelligibility and instrumental clarity, favoring musicality over raw power.
The AIO 3 includes a Wi‑Fi receiver and an RJ45 10/100M LAN Ethernet port for network connection, supporting UPnP and DLNA protocols. Bluetooth 4.2 with aptX codec ensures transmission with no noticeable loss from mobile devices.
The S/PDIF optical input accepts a digital signal from a TV or game console. The 3.5 mm mini‑jack provides a universal analog connection. The USB 3.0 port enables direct playback from a flash drive or hard drive, and can power devices up to 5 volts and 1 amp maximum.
The speaker decodes MP3, AAC (all variants), FLAC, WAV, APE, and Apple Lossless. Hi‑res playback reaches 24‑bit at 192 kHz, well beyond standard CD quality.
The Triangle AIO app, available on iOS and Android, centralizes control. Setup is done by pressing the Connect button on the back, putting the speaker into Wi‑Fi access point mode to receive the home network credentials.
The app integrates Spotify, Deezer, Qobuz, Tidal, Napster, Amazon Music, and TuneIn for Internet radio. The multiroom system supports up to twelve devices, with the option to form a true stereo pair or use group mode to play the same music everywhere.
Settings include an alarm function, programmable sleep, and favorite presets. An infrared remote control comes with the speaker, providing essential commands and bass/treble tone adjustments, which are not available in the app.
Yes, the Triangle AIO app allows you to configure two speakers in true stereo mode. Each AIO 3 then reproduces a full channel (left or right) instead of operating as an integrated single‑box stereo. This setup offers more pronounced channel separation and a wider soundstage, ideal for a fixed installation in a listening room.
The AIO 3 plays MP3 (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). Hi‑res playback reaches 24‑bit at 192 kHz via the local network and the 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 surface suits most bedrooms, offices, and kitchens. The 90‑watt output achieves 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.
