Wireless Speakers and WiSA Technology

Triangle Capella Connected Stereo System

Capella’s WiSA wireless audio transmission technology allows for flexible speaker placement throughout your home. Any audio source, whether from streaming services or connected inputs, is managed by the WiSA-enabled Stereo Hub, which streams the signal to the high-resolution speakers with minimal latency. This setup enables convenient positioning of the Stereo Hub near your AV equipment while allowing the speakers to be placed freely around the room.

Advanced Digital Signal Processing (DSP)

Capella’s active speakers boast a total power output of 2x100W, with each driver featuring its own converter and dedicated 50W amplification circuit. The next-generation DSP constantly monitors driver behavior to optimize performance, especially in low frequencies. Digital control of the crossover ensures a perfectly linear frequency response, resulting in deeper bass, clearer soundstage, and more detailed vocals.

Automatic Calibration

Capella’s automatic calibration technology adjusts the speaker’s sound response to your room’s acoustics and speaker placement, providing a balanced sound suited to all room types.

Precise Acoustic Settings

The optional Zen Microphone enables precise measurements during Capella’s automatic calibration. Data is collected and analyzed by the Triangle Capella app, which offers a wide range of settings for further sound customization. Users can adjust the response curve by increasing or decreasing selected frequency ranges to tailor the sound to their preferences.

Design and Elegance

Capella is available in four finishes: Brown Nebula, Astral Blue, Black Star, and Space White. The high-density cabinetry, with its luxurious craftsmanship and curved edges, is both aesthetically pleasing and acoustically optimized. The lacquered burr walnut essence reveals stunning wood grains that change with light and perspective. Champagne-finish anodized aluminum accents add a touch of elegance, turning these speakers into true sonic masterpieces.

Acoustic Engineering Expertise

Capella’s drivers benefit from Triangle’s extensive research and expertise, particularly from the 40th anniversary edition of the Esprit range. The horn-loaded tweeter features a 25mm magnesium alloy dome and a phase plug for harmonious high-frequency dispersion. The bass/midrange section is handled by a 16cm driver with a cellulose pulp membrane, a hallmark of Triangle speakers.
