The “High End” moved from Munich to Vienna this year, a big step for organizers “High End Society”. Here’s our next video report!
Michael Plessmann walks us through his system at room Level 1, 1.78 at High End Vienna 2026.
Why Michael Plessmann Started Soundspace Systems
Founder and CEO Michael Plessmann built Soundspace Systems to solve two things that bothered him in typical loudspeakers: a slight “grain” on top of voices and violins, and boomy, undefined bass.
Crystal-Clear Highs, Tight Bass
The result is a loudspeaker line aimed at crystal-clear highs, tight bass and natural-sounding voices — described in the room as “voices from heaven.” Visitors at the show listened to opera, jazz and rock on the system throughout the day.
Under the Hood: AMT Tweeter, Open Baffle and Active Sealed Bass
The top end comes from an AMT tweeter fitted with a waveguide and a first-order crossover. The midrange — key to natural-sounding voices — runs as a broadband open-baffle design, while the bass section is a sealed, active enclosure.
Seamless Integration Across the Range
Plessmann’s design goal was full integration between drivers: on a recording of a grand piano, for instance, the aim is that listeners never notice the sound moving between drivers.
