“An excellent price-to-performance ratio…”

“In short, it’s fair to say that it’s probably hard to find a better active speaker system for less money. The ULTIMA 25 ACTIVE 2 offers a well-thought-out and coherent overall package, with great practical versatility and exceptional sound quality.”
“Excellent price-to-performance ratio: the Teufel ULTIMA 25 ACTIVE 2 impresses with its flawless finish, practical features and first-class sound.”
“The Ultima 25 Aktiv 2 turns film sound into an experience…”
www.hifi.de
20.08.2026
“The Ultima 25 Aktiv 2 turns film soundtracks into an experience, just like its predecessor. The bass sounds more controlled, whilst the sound level remains consistently high. With music, there’s a slight lack of transparency and nuance, but the sound is still dynamic and largely uncoloured. Film sound enthusiasts will appreciate the option to upgrade to a wireless 2.1 or even 4.1 system.”
