Design & Build Quality
The Triangle Capella immediately stands out with its sophisticated, luxurious design. Unlike many wireless speakers that prioritize minimalism, Capella embraces a premium, artistic aesthetic.
Materials & Finishes
The speaker cabinets are made of high-density MDF, minimizing vibrations and ensuring clean, natural sound reproduction. The lacquered finish comes in four color options:
- Black Star – Sleek and modern
- Astral Blue – Unique and stylish
- Space White – Minimalist and clean
- Brown Nebula – Warm and elegant
Speaker Stand & Placement Considerations
One unique aspect of the Capella is its integrated metal base. Unlike traditional bookshelf speakers that require external stands, Capella is slightly elevated to accommodate its down-firing bass reflex port.
While this reduces placement sensitivity, it does mean you need a stable, solid surface for optimal performance. Some users might prefer traditional bookshelf stand options, which the Capella does not support.

Connectivity & Features
One of the biggest selling points of the Triangle Capella is its versatile connectivity, making it one of the most flexible wireless speakers available.
WiSA Wireless Technology
Unlike standard Bluetooth or Wi-Fi speakers, Capella relies on a dedicated WiSA wireless connection for audio transmission. This allows for lossless 24-bit/96kHz audio streaming without latency issues, ensuring a high-fidelity listening experience.
Stereo Hub: The Brain of the System
Instead of integrating all inputs into the speakers, Triangle uses an external Stereo Hub that connects wirelessly to the speakers. This approach allows for more input options and better signal management.
Input & Streaming Options
- HDMI ARC – Perfect for TV connection

Sound Performance: Audiophile-Grade Audio
The Triangle Capella follows the brand’s signature sound philosophy, delivering a detailed, lively, and natural audio experience.
Tweeter Performance: Crisp, Airy Highs
The 25mm magnesium dome tweeter, placed in a horn-loaded waveguide, delivers crystal-clear treble with exceptional detail retrieval. Unlike some speakers that sound overly bright, the Capella keeps the highs smooth yet engaging, making it perfect for jazz, classical, and vocal-driven music.
Midrange Performance: Natural & Expressive
The 16cm cellulose mid-bass driver produces rich, organic midrange tones. Vocals and instruments sound lifelike and present, ensuring an immersive experience for genres like rock, acoustic, and orchestral music.
Bass Response: Deep, Controlled Lows
The down-firing bass reflex port ensures tight, punchy bass. While it doesn’t match the earth-shaking power of a Devialet Phantom, it delivers clean, well-defined low frequencies.
🔹 For bass lovers: If you want extra low-end punch, the Capella includes a subwoofer output, allowing you to add a dedicated sub for deeper bass extension.
User Experience & Setup
One of the biggest advantages of the Triangle Capella is its straightforward setup process. Unlike traditional wired hi-fi speakers, there’s no need for speaker cables, as the Stereo Hub communicates wirelessly via WiSA.
Setup Process
- Connect the Stereo Hub to a power source
- Pair the speakers with the Hub (automatic WiSA connection)
- Connect your preferred audio source (HDMI, Bluetooth, USB, etc.)
- Enjoy high-fidelity sound without any complicated wiring
User Controls & Remote
A dedicated remote control is included, allowing you to adjust volume, inputs, and playback settings without needing a smartphone. However, there is no dedicated mobile app, meaning Wi-Fi setup is handled through Google Home.
