THE 28 SUB PRO SQUARED: The Future of Bass Has Arrived
Revolutionising Home Theatre Bass
The 28 Sub Pro Squared is not just a subwoofer—it’s a breakthrough in low-frequency performance. Inspired by a discussion with Trinnov CEO Arnaud Laborie at the ISE Show, this subwoofer was engineered to push the boundaries of bass reproduction. After extensive research and development, it features an ultra-powerful 28-inch composite sandwich cone, constructed from multiple layers of Rohacell. With a cone surface equivalent to a 32-inch round subwoofer, it sets a new benchmark for deep, powerful, and precise bass.
Unrivalled Performance in Any Space
Designed to deliver exceptional output with a minimal footprint, the 28 Sub Pro Squared is the ideal solution for high-performance home theatre setups. Whether used in a subwoofer cluster, Trinnov WaveForming, Dirac ART, double bass arrays, or single bass arrays, it integrates seamlessly while producing earth-shaking, infrasonic frequencies—bass that is felt as much as it is heard.
It also extends beyond the standard 120Hz LFE cutoff, making it the ultimate kick woofer for high-impact effects. Whether it’s the deep resonance of an explosion or the sharp crack of a gunshot, every sound is reproduced with incredible clarity, precision, and intensity.
Precision-Engineered for Maximum Impact
With a depth of just 30 cm, the 28 Sub Pro Squared fits into spaces where other subwoofers cannot, yet it delivers unrivalled performance. Its compact yet commanding dimensions—80 cm wide and 100 cm high—allow for close woofer spacing, ensuring perfect coupling in bass arrays with control up to 120Hz.
Cutting-Edge Engineering for an Immersive Experience
This subwoofer is engineered to deliver not just deep bass, but accurate and controlled bass. With an ultra-powerful motor structure, it generates a perfect planar wave front, offering high efficiency, extreme power handling, and low system Q. The result is bass that is tight, fast, and dynamic, ensuring every note and effect is delivered with stunning accuracy.
Experience Sound Like Never Before
The 28 Sub Pro Squared by Ascendo is more than just a subwoofer—it’s a gateway to an immersive audio experience. Whether for blockbuster movies, high-impact gaming, or music, it delivers bass that can be felt in the chest and throughout the room.
