Why Infrasonic Bass Is Necessary For Private Cinema

Infrasonic bass is an essential part of any high-performance private cinema. It pressurizes the room and evokes the physical response that is intended by more movie soundtracks than you might think.

True infrasonic subs are extremely hard to engineer, not inexpensive, and work in tandem with other subs in the theater to do their part, extending bass into the single Hz digits. This isn't about boomy, bloated bass, or marketing claims by me-too big cone alternatives. The demands of these frequencies and durations found in some soundtracks will quickly separate Ascendo from those masquerading as me-too.

When calibrated correctly (timing, phase, level, etc.) with the rest of the theater channels, the result of including Ascendo infrasonic bass is an engaging, completely immersive experience one doesn't forget. These frequencies are often used in quiet passages that can at first be very subtle, causing the body to sense and react in a, "What the heck was that?!" followed by a dynamic contrast and system headroom requirement that separates really good home theaters from exceptional, private cinemas.

Adam Pelz says about infrasonic sounds, "If you live in a busy downtown environment, the next time you go outside, pay attention to the deep bass. Road noise, cycling wind, railways, subways, etc. Or even the thud of a heavy car door shutting. My favorite is just average footfall noise from people walking on a floor above you. They generally fall into the 10-16Hz range. HVAC compressors and variable speed motors also. We are surrounded by very low frequencies, and I think they add a tremendous sense of space, realism, "believability"."

The photo above is Ascendo's smallest infrasonic sub, the SMSG24. Its huge cone surface area and?incredible 90mm of linear stroke - represents a world record for cinema subwoofers - allow it to move a gigantic volume of 10 liters of air per stroke to pressurize the room. 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 favor of this unique design compared to stacked multiple smaller subwoofers.

Its ingenious design?allows the SMSG24 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?perfect alignment of?the SMSG24 to any existing setup by adjusting crossover, phase, and amplitude response.

Private Cinemas can absolutely benefit from including infrasonic bass speakers in the system. Just reach out and ask us to help with your project.
