ASCENDO Immersive Audio, a German company known for its high-performance infrasonic subwoofers, has just announced a game-changing amplifier: the AIA2-10K2 IS 1U. Designed to handle frequencies as low as 3Hz, it’s built specifically for the demands of infrasonic sound. You can check it out in action at Integrated Systems Europe (ISE) 2025, running February 4–7 at Stand #2E300.
Infrasonic frequencies are sound waves below the threshold of human hearing, typically under 20Hz. While we might not "hear" these frequencies in a traditional sense, we certainly feel them. They can make a room vibrate, add a sense of pressure, or evoke emotional responses, especially in movie soundtracks or music. The impact of these deep frequencies is critical for delivering a truly immersive home theater experience.
However, reproducing these frequencies accurately isn’t easy. It requires not only high-quality subwoofers but also an amplifier capable of delivering sustained power at ultra-low frequencies. This is where the AIA2-10K2 IS amplifier steps in.
ASCENDO identified a significant gap in the market: even the most robust commercial amplifiers often fall short when tasked with powering infrasonic subwoofers. Most amplifiers designed for public address (PA) systems or concerts are optimized for short bursts of dynamic power—ideal for high-energy events but unsuitable for home theaters that demand continuous, sustained output. PA amplifiers also rarely support frequencies below 35Hz, making them ill-equipped for the infrasonic range.
These limitations mean that typical amplifiers struggle to provide the consistent and stable output required to drive the deep, immersive bass that many modern films and music tracks rely on.
ASCENDO’s AIA2-10K2 IS 1U amplifier directly addresses these challenges. Here’s what sets it apart:
ASCENDO’s move to create the AIA2-10K2 IS reflects a growing demand for home theater systems that deliver the same emotional and physical impact as commercial cinemas. By ensuring that the deepest frequencies are reproduced with precision and consistency, ASCENDO is catering to both audiophiles who crave fidelity and enthusiasts who want to feel every rumble and shake in their favorite blockbuster movies.
“This is a game changer because it means home theaters can deliver bass like the audience has never heard—or felt—before,” says Geoffrey Heinzel, Co-Managing Partner of ASCENDO. “Whether it's the deep rumble of a distant thunderstorm or the precise, tight impact of a gunshot, your audio will be richer, clearer, and more powerful.”
The amplifier will be showcased at ISE 2025, where attendees can witness firsthand the difference continuous power makes in the infrasonic range. If you’ve ever wondered what it feels like to experience bass so deep it’s almost tactile, this is your chance.
