The Twin Tower of Power
The new HYPERSPHERE is created to be the largest, fastest and most dynamic system ever built in the history of high-end audio.

In his musical journey of creating timeless icons, this hyperspherical loudspeaker system is the culmination of nearly 70 years of research into the enjoyment of music.

Hypersphere Concept 1700mm
While the current ACAPELLA line-up already includes some impressive musical titans like the HYPERION (780mm horn series) or the outstanding SPHÄRON Excalibur (1050mm + 580mm horn series), the HYPERSPHERE goes to extremes.
With its brand-new and massive 1700mm hyperspherical horn, driven by a brand-new ultra-lightweight 1.7" driver, the HYPERSPHERE opens the door to full music enjoyment. This horn construction transmits a full seven octaves! in one unit. As a result, the entire range of lower mids, mids, and highs are effortlessly, quickly, and precisely reproduced in a way that no other speaker can match. The low frequencies are handled by eight 15" woofers in two enclosures that operate in parallel and, thanks to their intelligent horn-loaded coupling concept, act as a single large unit. But that's not all...

High End 2025 Report ReMusic Online.
"I had the counter-proof with one of the most significant listenings, the one expressed by the piano solo tracks."
[ ... ] "...two meters from the speakers, the illusion of listening and "seeing" the instrument, in all its sound articulation was breathtaking." [ ... ] "Like an F1 car (...) it can "kill you" with its performance on a suitable circuit."

Credo
Within our emotional quality of life, music is a key element. Playing musical instruments makes it authentic and immediately tangible. For 70 years, we have been committed to bridging the gap between the musical and the technical worlds. When building our regular but impressive ACAPELLA loudspeakers, there was always the search for the extreme, for the ultimate loudspeaker. Mastermind Alfred Rudolph presents his final masterpiece of loudspeaker design in all its dimensions as the excellence of his lifelong musical journey. It is not only the loudspeaker architecture, but also the electro-technical knowledge, the resonance optimization, the material know-how, as well as the knowledge of spherical and hyperspherical horns. Last but not least, the music has to be "in time". Our loudspeakers are like a musical instrument, where all the drivers and the cabinet work "in time", which is one of the HYPERSPHERE's strongest skills.
