The world’s best speakers made to vanish


 HIDDEN ARCO speakers can be completely incorporated into your architectural project design, cleverly utilizing a setup with multiple speakers to deliver a concert-like perception of singer and instruments.


Literally every surface of the interior, such as a wall, a painting, a suspended ceiling, a piece of furniture can be used to become a high-quality DML loudspeakers type sound source. 

 This is why we call it Architectural or Invisible Audio: Installed into the wall or ceiling and then finished over with the surrounding surface, invisible speakers deliver ambient music that emanates throughout the space with no visual footprint, bring the depth of emotion of high-fidelity sound. These are truly invisible Swiss audiophile loudspeakers made for integrators, architects and interior designers.

What does it mean that these speakers are optimised for Hidden Amp? When these speakers are connected to Hidden Amp, Amp will automatically detect them, and automatically adjust the sound to be best for that speaker. This is only possible because we designed the speakers from the ground up with Hidden. How many pairs of speakers can be installed together on a single Hidden Amp? The Hidden Amp has been designed to power up to three pairs of Hidden Architectural speakers on a single Hidden Amp. Can I use these speakers with amplifiers other than Hidden Amp? The Hidden Architectural speakers will work with most amplifiers. Where should my in-wall speakers be installed? If you are using the in-wall speakers to replicate sound from your TV, the speakers should be installed a few inches away from the right and left edges of the television, with the tweeter of the speaker installed as close to ear level (from the seating position) as possible. If you are using the in-wall speakers as distributed audio speakers and not flanking a television, we recommend placing them in a location that will provide the best coverage for the room.
