Description

THE64 SUB PRO PASSIVE SEALED — A New Dimension of Power, Precision, and Sonic Authority


The 64 SUB PRO PASSIVE SEALED Infrasonic Subwoofer does not just play bass — it opens a portal to the unknown. Designed to go far beyond the boundaries of what was thought physically possible, this monumental subwoofer reaches depths few have ever felt, let alone heard. It is the definitive proof that infrasonic reproduction is not a luxury in high-end cinema — it is a necessity.


This is no ordinary subwoofer. It is a revelation.


At its heart beats a custom-engineered 64” driver, the second-largest cinema subwoofer driver ever built — dwarfed only by its sibling, THE100 SUB PRO PASSIVE. Fueled by 10–22 kW of DSP-controlled power through ASCENDO’s cutting-edge Speaker Management Technology, it commands the air with absolute authority.


Unmatched Performance. Unrivaled Impact
With each full excursion, THE64 displaces as much air as 40 18” subwoofers — a figure that is almost inconceivable until experienced. Its output is monumental:

  • Up to 148 dB peak SPL
  • 113 dB LFE reference level at 5 Hz — in large rooms
  • Effortless frequency response down to 1 Hz

Yet with all that force, it remains incredibly fast and surgically precise. Thanks to its sealed, ultra-rigid braced enclosure and exceptionally low resonance frequency, THE64 SUB delivers a lightning-fast impulse response and class-leading low group delay below 20 Hz — outperforming every other subwoofer on the market in its class.
 

Emotionally Unstoppable
THE64 SUB PRO PS doesn’t just shake the room — it reshapes expectations. It differentiates even single-digit frequencies with stunning clarity, rendering every infrasonic nuance with high-resolution detail, structure, and explosive speed. It captures both the weight of a collapsing mountain and the whisper of tectonic tension with equal ease.


This is not about bass. This is about presence, power, and physical immersion — the kind that turns sound into a living, breathing force.


The Future of Home Theater — and Beyond
For world-class home cinemas seeking the absolute pinnacle of low-frequency performance, THE64 SUB is not just an upgrade, it’s a transformation. But its precision, speed, and low distortion also make it the ultimate low-frequency solution for the most demanding and refined two-channel listening environments — where absolute control and natural integration are essential.


It redefines what “reference” means in both cinema and music, laying the foundation for a listening experience without compromise.


There is nothing else like it. There never has been. And until you experience it, you’ve never truly felt bass.
