INtroducing the Sub 4-12 INFRA
The Sub4-12 INFRA is a compact yet powerful infra-subwoofer designed around four in-house-engineered 12″ long-throw drivers.
Artcoustic’s new Sub 4-12 INFRA redefines what’s possible in infra-bass design. With four 12” long-throw drivers and an advanced 6th-order bandpass architecture, it delivers astonishing power down to 12 Hz, while remaining compact enough to fit behind a cinema screen.
For designers and installers, it means true cinematic depth without compromise — low amplifier demand, exceptional reliability, and a form factor made for integration.
As Kim Donvig explains, “It’s the subwoofer that carries the soul of any cinematic experience” — and this one was built to deliver it with effortless power.
“Designing subwoofers has always been one of the greatest challenges in loudspeaker engineering - and yet, it’s the subwoofer that carries the very soul of any cinematic experience.
When we began developing the Sub 4-12 INFRA, we set out to create a true infra-subwoofer capable of linear, effortless energy below 20 Hz - within a footprint that fits behind a cinema screen.
Instead of one huge driver, we chose four precision 12-inch units, working in perfect phase alignment. Together, they equal the cone area of a 24-inch driver - but with far lower distortion, higher power handling, and greater reliability.
Our refined 6th-order bandpass architecture allows extreme performance from a surprisingly compact enclosure. The result is our most powerful and most extended subwoofer ever:
• F10 at just 12 Hz - true infrasonic depth
• 126 dB at 30 Hz - immense dynamic output
• Compact footprint - easy to integrate, easy to hide
The Sub4-12 INFRA represents years of design evolution - where acoustic science meets installation practicality. It’s built to work harder, play deeper, and deliver impact that feels effortless and real.
