Triangle AIO Twin Review: All-in-One Wireless Speaker System for High-Quality Sound

Experience the versatility and impressive sound of the Triangle AIO Twin, a wireless all-in-one speaker that packs high-fidelity features into a stylish, compact design.

Unpacking the Triangle AIO Twin: A Compact Powerhouse

If you’re anything like me, discovering a music system that promises top-tier sound without swallowing your whole budget feels like finding a hidden gem. Enter the Triangle AIO Twin wireless speaker—a wireless all-in-one speaker system that reminded me of the revered KEF LSX II wireless speaker, but at roughly half the price. That alone piqued my curiosity.

These systems that bundle amplification, streaming, and connectivity into one neat package are becoming the go-to for anyone wanting to elevate their home audio without juggling a dozen devices. They’re practical, sleek, and versatile—perfect for smaller spaces or anyone wanting to cut down on clutter.

The Triangle AIO Twin looks like a pair of regular bookshelf speakers, but don’t let that fool you. It’s a fully loaded music system with an impressive feature set and sound quality that punches well above its price tag.

Price: $1000

Design and Build: Style Meets Practicality

From the moment I unpacked the Triangle AIO Twins, I was hooked by their design. They strike a perfect balance—not tiny like some desktop speakers, but much more space-friendly than larger bookshelf models. This middle ground means you can place them flexibly, even in cozier rooms. Just remember to avoid pushing them too close to the wall since their rear ports need breathing room.

Here's what makes them tick:

• Power: 2 x 50W amps
• Drivers: 25mm tweeter, 13cm mid/bass driver
• Bluetooth: 5.0 with aptX, aptX HD, aptX LL, SBC, AAC
• Streaming: Wi-Fi and internet radio support
• Streaming Services: Spotify, Tidal, Qobuz, Deezer, Amazon Music, Napster
• Audio Resolution: Up to 24-bit/192kHz
• Inputs: Ethernet, RCA/Phono MM line-level, 3.5mm AUX, optical, USB-A
• Output: Subwoofer out
• App & Remote Control: Both included
• Dimensions (HxWxD): 23.5 x 16.5 x 30.4 cm
• Weight: 10.3 kg total
• Finishes: Six vibrant options including “Abyss Blue,” “Frost White,” and “Graphite Black”

The build quality impressed me, especially the gently rounded edges and fabric grilles that complement the cabinet finish. The aluminum feet with rubber pads add a nice touch, isolating the speakers to minimize vibration and protect furniture surfaces. Just a heads-up: one of the rubber pads on my test set kept coming loose, so gentle hands are advised when moving them around.

Feature-Rich Functionality: Built for Every Listening Style

Unlike some active speakers where each cabinet houses its own amplifier, the Triangle AIO Twin follows a master/slave setup. That means the right speaker is the powerhouse, hosting the 50W amplifier, streaming module, and all the inputs. It then sends audio via wire to the left, passive speaker. Both feature the same 25mm tweeter and 13cm midbass driver combo.

The color-coded buttons on the back of the right speaker are a neat visual cue, matching the LED color on the front to indicate the active input source—talk about user-friendly design!

A slim remote control comes in the box, perfect for volume tweaks and basic playback control. But personally, I found the Triangle AIO app to be my go-to when streaming wirelessly—it’s smooth, intuitive, and makes managing your music a breeze.

Whether you want to stream music from your phone via Bluetooth, tap into your home network’s digital files, or even spin vinyl, the AIO Twin has you covered. It can also double as a TV soundbar alternative, thanks to its diverse input options.

With Bluetooth 5.0 supporting high-res codecs like aptX HD and the usual SBC and AAC, plus Wi-Fi and Ethernet connectivity, you’re set for seamless streaming. Ready-made integrations with Spotify, Tidal, Deezer, Amazon Music, Qobuz, and internet radio round out the experience. High-resolution audio support up to 24-bit/192kHz means your digital collection shines.

But the real cherry? An integrated phono preamp! This allows you to plug in a turntable with a moving magnet cartridge straight into the system—no external phono stage needed. A fantastic feature for anyone dipping their toes into vinyl without extra gear.

Physical connections include:

• Optical digital input
• RCA analog (switchable between line and MM phono)
• 3.5mm AUX input
• USB-A port (for device charging)
• Subwoofer output

Setting up the Triangle AIO Twin is refreshingly straightforward. The Triangle AIO app is comprehensive and responsive, making streaming and daily use effortless. Honestly, the only tweak I’d love to see in the future is an onboard equalizer to tailor the sound further.

For those who want to expand, the system supports multi-room setups—pair multiple Twins or add the AIO 3 wireless speaker for a seamless home audio ecosystem.

Sound Quality: Small Size, Big Performance

Now here’s the magic part. You might be tempted to treat these as just desktop speakers, but they deserve a place on dedicated stands. Once properly set up, they come alive with a lively, enthusiastic spirit that embraces all genres and recording qualities. It feels like the speakers want nothing more than to get you hooked on the music.

Take Four Tet’s “Circling,” a complex test of rhythm and dynamics. The AIO Twin handled it with a playful bounce and razor-sharp precision, effortlessly organizing layered instruments and textures. That kind of control at this price is impressive.

Though you can’t expect earth-shaking bass from these compact cabinets, the bass lines were tight, punchy, and well-defined—propelling the groove without any muddiness or lag. Run The Jewels’ “Legend Has It” came through with power and clarity, with every vocal and beat sharply defined.

The sound is well balanced across the spectrum: solid bass, clear vocals, and sparkling highs that never sound harsh.

Charlotte Lawrence’s voice on Joke’s “On You” floated beautifully in a spacious soundstage, delivering crystal-clear vocals wrapped in just the right amount of warmth. The system also packs enough punch to lend weight to more powerful ballads when needed.

Whether streaming Tidal over Wi-Fi, Apple Music via Bluetooth, or playing a CD over optical, the Triangle AIO Twin showed off a lively, engaging sound that pulls you in.

The phono preamp was where I noticed some limitations. While connecting the system to a stellar Pro-Ject Debut Pro turntable retained the energetic vibe, the sound wasn’t as clean or expressive compared to digital inputs. It’s still listenable, but for serious vinyl lovers, an external phono preamp hooked into the line-level input would offer better fidelity.

Final Thoughts: A Winner for All-in-One Audio Lovers

After spending quality time with the Triangle AIO Twin, it’s clear these speakers want to stick around. That enthusiasm for music shines through in every note, making it easy to fall in love with this neat, elegant system that does (almost) everything.

If you’re hunting for an all-in-one music system with genuine Hi-Fi sound without breaking the bank, the Triangle AIO Twin deserves a spot on your shortlist.

Ratings:

• Sound: 5/5
• Build: 4/5
• Features: 5/5

The Triangle AIO Twin organizes complex layers of sound with a light confidence—a true masterclass in compact performance.
