ASCENDO Immersive Audio GmbH has launched its latest innovation in home cinema audio, introducing the THE64 SUB PRO PASSIVE INFRASONIC SEALED and THE100 SUB PRO PASSIVE INFRASONIC SEALED subwoofers. These 64-inch and 100-inch models, succeeding the acclaimed 50-inch and 80-inch designs, set a new benchmark for ultra-low-frequency performance, delivering bass that is as visceral as it is precise.

Geoffrey Heinzel, Co-Managing Partner of ASCENDO, stated, “We are proud to lead in infrasonic bass. These subwoofers, the largest in the world for home cinema, offer unmatched power, efficiency, and speed, creating an emotionally immersive experience for state-of-the-art home theaters and music systems.”

Engineering Breakthroughs for Unparalleled Performance

The THE64 and THE100 feature significant upgrades in motor, suspension, and enclosure design, pushing the limits of low-frequency reproduction. Key improvements include:

  • Enhanced Suspension System: A quad-spider configuration with advanced materials optimizes excursion, ensuring noise-free operation and improved linearity even at extreme levels.

  • Deeper Bass Extension: Lowered driver resonance and optimized enclosure dimensions achieve unprecedented f3 points, extending frequency response into the infrasonic range.

  • Superior Noise Performance: A refined compliance curve enhances control and minimizes distortion at ultra-low frequencies.

  • Robust Enclosure Design: New single-piece surround tooling and improved internal bracing increase rigidity, while multi-density damping materials reduce resonance and group delay for perfect impulse response.

  • Increased Enclosure Depth: Both models feature a 100 cm deep cabinet, further enhancing infrasonic performance.

Serviceability and Practicality

ASCENDO has also prioritized ease of maintenance, introducing a field-replaceable re-cone kit for quick and efficient servicing, ensuring long-term reliability for these massive subwoofers.

A New Standard in Home Cinema Audio

Replacing the THE50 and THE80 models, the THE64 and THE100 reflect ASCENDO’s adoption of industry-standard naming conventions, incorporating driver basket dimensions. These subwoofers are designed for audiophiles and home theater enthusiasts seeking unmatched power and precision in bass reproduction.

With these advancements, ASCENDO solidifies its position as a leader in infrasonic audio, offering subwoofers that deliver an immersive experience that must be felt to be believed.

Publisher

Marco Lisi is the publisher of Best of High End, part of AV Concepts BV. His path into audio started early: as a teenager he was drawn into the world of free radio, presenting shows and living immersed in music every day. In his early twenties he ran his own production studio for five years, creating jingles and commercials — hands-on training in sound design, pro-audio workflows, and critical listening through studio monitors that still shapes how he evaluates gear today. He also spent years DJing in clubs before moving into publishing, first at two earlier online magazines before founding Best of High End. His hi-fi and home cinema passion was inherited from his father, an inveterate system-swapper. Marco's first setup — a confirmation gift — paired AKAI separates with entry-level Bowers & Wilkins speakers, a brand he stayed loyal to for years as his system grew from stereo into full surround and home cinema. Like many enthusiasts, he went through an extended "audiophile" phase chasing the next upgrade, before settling into a more grounded view: gear as a means to enjoy music and film, not an end in itself. Years of critical listening have given him a well-trained ear — the ability to characterize a system or pinpoint a change in the chain quickly and accurately. Just as important, his teaching background (a Belgian "regent" degree in Dutch language) gives him the tools to translate those listening impressions into clear, readable writing.
