Your neighbours will hate this: ASCENDO’s new 100-Inch infrasonic subwoofer is a wall-rattling, eardrum-destroying home theatre beastIf you’ve ever watched Back to the Future and thought, ‘I wish my home theater could physically launch me into a bookshelf like Marty McFly’ – well, dreams do come true.
ASCENDO just announced two jaw-dropping additions to its subwoofer lineup: THE64 SUB PRO PASSIVE INFRASONIC SEALED and the absolutely absurd THE100 SUB PRO PASSIVE INFRASONIC SEALED. As the names suggest, these are 64-inch and 100-inch passive sealed subs, designed to generate bass so low you’ll feel it in your DNA.
The German audio specialists aren’t new to big bass. They previously offered 50- and 80-inch infrasonic models, but clearly decided those were simply… too modest. The new 64- and 100-inch subs build on the legacy of those models and have been completely re-engineered for deeper extension, tighter control, and “unparalleled sonic precision at infrasonic frequencies”.

“These two new subwoofers are the largest in the world for home cinema,” says Geoffrey Heinzel, Co-Managing Partner of ASCENDO. “[They] are incredibly powerful, efficient, and fast.”
So what exactly has been upgraded?
First, the suspension system has been overhauled with repositioned quad spiders, allowing greater excursion across the entire frequency range – both linear and nonlinear. To handle that movement silently and smoothly, ASCENDO uses carefully selected spider fabrics and resins that ensure high compliance without introducing noise, even during extreme playback conditions. Ultra-low frequency reproduction has also been improved considerably, beyond what any previous woofer design has achieved.
The speaker cabinets themselves have also seen significant refinement. They now feature a single-piece, custom-shaped surround that better supports the increased demands of the massive drivers. Optional application-specific enclosures for both THE64 and THE100 are also available and now feature improved internal bracing, which enhances rigidity and helps the cabinets handle all that energy without unwanted vibration. Meanwhile, ASCENDO’s multi-density damping materials have been fine-tuned to reduce resonance and group delay, resulting in a clean, punchy impulse response.
In short, these new subs are faster, deeper, more precise – and still terrifyingly large.
Thankfully, ASCENDO has also made them easier to service. A new field-replaceable re-cone kit means that if something does blow (or, let’s face it, if your curious friend pokes the cone), it can be quickly repaired without shipping the entire Death Star-sized unit back to Germany.
THE64 now replaces ASCENDO’s former 50-inch model, while THE100 steps in for the outgoing 80-inch version. That said, if you’re still wondering why someone would need a 100-inch subwoofer, you’re probably not the target market.
