The speaker enclosure is made of Finnish, eco-friendly, and recyclable UPM Formi biocomposite material.

In addition to the RCA connection, AALTO 1pro also includes a balanced Phoenix connector, which enables installation in various mounting locations.

Thanks to comprehensive sound color adjustments, the speaker can be installed in acoustically challenging places such as the ceiling, corner, or wall without compromising sound quality.


The design of the AALTO 1pro enclosure takes into account a unique, clear Scandinavian design language, as well as the constraints imposed by the laws of acoustics.

The double curved surfaces of the enclosure ensure natural shape rigidity, and the forward tapering shape minimizes standing waves inside the enclosure.


The technical implementation follows the well-known formula of all AALTO speakers - the bass driver of AALTO 1 produces deep, powerful and incredibly low-reaching bass, while the WLR1 tweeter unit delivers bright high frequencies and a clean midrange that seamlessly integrates with the bass.

AALTO 1's reproduction is powerful, dynamic, and consistent. The sound image is in a class of its own for a speaker of its size.
