Ascendo The32 Sub Pro-Passive Sealed Infrasonic Subwoofer

Key figures: 82 cm / 32" custom-built super-woofer, 90 mm of linear travel – the world record for home theater or even commercial cinema subwoofers. The The32 SUB PRO plays in its own league. Authority and impact, speed, dynamics and differentiation, all these attributes the The32 SUB PRO evolves when playing down to the deepest notes in the single digit range. This opens up a new world in lowest bass reproduction. Any comparison will illustrate the sovereignty of its infrasonic bass capabilities.

Displacing an incredible volume of 16.6 liters or half a cubic foot, the The32 SUB PRO pushes as much air per maximum stroke as fifteen standard 18" subwoofers. The The32 SUB PRO allows not only to reproduce lower frequencies, but also a much faster group delay at the same frequencies than the commonly used 18”, 15” and 12" subwoofers in todays home theater and commercial cinema configurations.

The performance of the The32 SUB PRO is unparalleled. This infrasub complements both state-of-the-art cinemas or home theater setups to extend LFE channel reproduction or benefits the best high-end speakers. It dramatically improves the overall performance of all speaker systems.

The32 SUB PRO - more depth, image, structure, resolution, volume, dynamics equals more fun
