ASCENDO leads the industry in infrasonic bass. Infrasonic bass pressurizes the space, making sound visceral.

“The Ascendo bass system re-writes bass performance in our view. The SMSG24 infrasonic is a statement.”

Infrasonic subwoofers reproduce frequencies below human hearing range, adding another layer of depth to the audio that you feel rather than hear.
This isn’t just bass – it’s a primal force, that pulls you into the heart of the audio, into pure sensation.

A huge cone surface area, huge 90mm of linear stroke, representing a world record for cinema subwoofers.
Allowing it to move a gigantic volume of 10 liters of air per stroke to pressurize the room, with authority, rendering those notes with much more power, structure and resolution.

By offloading the deepest bass to the infrasonic subs handling the tectonic shifts, your main subwoofers stop struggling and deliver cleaner, tighter mid-bass.
Your content now has an effortless quality, enhancing enjoyment from the highest to the lowest frequencies… No compromises. No strain. Just earth-shaking immersion.

Due to its ultra-low resonance frequency and its sealed enclosure design the group delay is several times faster than the smaller 18″, 15″ or 12″ subwoofers at the same frequency. Also the acoustic power output per cubic inch is by far in favour of this unique design compared to stacked multiple smaller subwoofers.

Its ingenious design allows the The24 SUB PRO AS to produce frequencies in the infrasonic frequency range with authority, reaching down lower than subwoofers with a smaller diaphragm surface ever will. At the same time this infrasub renders those notes with much more power, structure and resolution.

This ASCENDO-developed 62 cm / 24″ super woofer is powered by one of the best high current amplifier designs delivering 6000 watts of power for multiple seconds. Its state-of-the-art DSP control allows to perfectly align the The24 SUB PRO AS to any existing setup by adjusting crossover, phase and amplitude response.

The SMSG24 ideally suits NOT ONLY all types of cinemas but also high-end stereo systems, as much of the spacial room information of the recording environment in a great audiophile recording is contained in the sub 30Hz audio band, you will hear more details in mid and high frequencies.
