Ascendo Pushes World's Largest Subwoofer Record Further with New 64" and 100" Models

Home theater specialist Ascendo Immersive Audio is a recognized pioneer of infrasonic subwoofer development, impressing the custom integration sector with its early 24, 32, 50, and even 80-inch models. Seeing global sales continuing to grow, the German company now announced THE64 Sub and THE100 Sub, which Ascendo says push the boundaries of low-frequency reproduction with advanced engineering, deeper extension, and unrivaled control.
 
Ascendo Immersive Audio offers a comprehensive range of high-performance speakers and electronics, including active and passive precision subwoofers, all purpose-built for home theater. When Ascendo introduced its 80" infrasonic subwoofer, many doubted that it would be even a real product. After all, the 50 Sub Pro model, introduced in 2017, was understood by almost anyone in the industry that saw it at a show (yours truly included) as a booth prop, intended to attract visitors and generate Instagram selfies. It was hard to believe that anyone would be interested in a 50" infrasonic subwoofer, but the reality is that Ascendo did it because it had orders, and the company was even surprised to see a few copies introduced in the market shortly after.

Again, for the 80" subwoofer, the Ascendo engineering team had to explore uncharted territory in dimension and performance, and had to overcome many mechanical, magnetic, and electrical challenges to produce it. After the pandemic, Ascendo returned to trade shows with a clear engineering statement from a company that had actually done it. The 80 Sub Pro was described as "the most powerful and precise cinema subwoofer in the world," claiming speed, definition, and the ability to generate frequencies in the single-digit frequency range.
  The new 64 and 100-inch models have benefited from those developments. Every aspect of the two new massive subwoofers — from motor and suspension to enclosure and damping — has been re-engineered to deliver deeper extension, greater linearity, and unparalleled sonic precision at infrasonic frequencies, including an upgraded suspension system with quad spiders, repositioned and optimized to deliver significantly more excursion across the entire range. Advanced spider materials include carefully selected spider fabrics and resins, providing higher compliance and noise-free operation, even at extreme excursions.

"We are proud to be the leader in infrasonic bass. Our continuous innovation in this category translates to an extremely high-performance, emotionally connected experience that enriches state-of-the-art home theaters and music reproduction systems with bass you can feel," says Geoffrey Heinzel, co-managing partner, and head of sales & marketing of Ascendo. "These two new subwoofers are the largest in the world for home cinema, and are incredibly powerful, efficient, and fast."
 
According to Ascendo, the THE64 Sub Pro and THE100 Sub Pro noise performance has been enhanced beyond what any previous woofer design has achieved at ultra-low frequencies. An optimized, shallower compliance curve means improved linear motion and control, while a lowered driver resonance, combined with optimized enclosure dimensions, enables even lower f3 points for deeper bass extension.
  As the company explains, a new single-piece, custom-designed surround tooling creates a surround shape that supports greater and more linear excursion. Additionally, optional application-specific enclosures for both subwoofers feature improved internal bracing that builds on Ascendo's standards for rigidity and control. Ascendo has also fine-tuned its multi-density internal damping materials to lower the system’s resonance frequency — significantly reducing Q — and achieving improved impulse response with ultra-low group delay. The required enclosure depth has been increased to 1m (nearly 40 inches), further extending the frequency response into the infrasonic region. 

Other improvements to the previous versions of Ascendo's large infrasonic subwoofers include a new field-replaceable re-cone kit, developed to allow quick and efficient serviceability in the field. THE64 replaces Ascendo's existing 50" model, while THE100 replaces the 80" model, with updated references that reflect the pro industry method of including the driver basket in the dimensions.
 
"These advancements position the THE64 and THE100 subwoofers as the most advanced infrasonic transducers ever produced — delivering breathtaking power and precision that must be heard to be believed," the company states.
