"Trenner & Friedl’s little Suns bowled me over and blew me away. Rarely have I heard a loudspeaker with so many essential gifts in so small a package." – Ken Micallef, Stereophile

Sun, the most compact of our loudspeakers, has many things in common with its big brother Ra: Both are designed to approximate the proportions of the golden section, and like Ra, Sun relies on a coaxial driver for sound reproduction. In the high-frequency region, a 2.54 mm silk-dome tweeter works its magic, while the mid-bass cone is constructed with black-anodized aluminum and, with its 12cm diameter, delivers bass that is nearly as deep as RA – even though our baby naturally does not play as loud in this range as the big brother…

Sun does not interpret music, rather, he reproduces it: neutral, precise, and wonderfully coherent.

With its coaxial construction, Sun is in the position to perfectly depict the room and space of the recorded event.

Placement also raises no problems: Sun can be placed near the back wall and even feels at home in a bookshelf.

You can easily lift Sun with one hand, but don’t be fooled by its compact size, as it delivers serious musical weight.

Just as a small point in the heavens illuminates the entire day, Sun fills the room with sound.
