The Sub 4-12 INFRA is a compact yet powerful infra-subwoofer designed around four in-house-engineered 12″ long-throw drivers. Its advanced 6th-order bandpass enclosure is optimised for maximum output in the 15–20 Hz range, delivering bass you don’t just hear - you feel.
Unlike conventional subs, it achieves extreme infrasonic performance with outstanding efficiency, keeping amplifier requirements low while maintaining clean, controlled sound. The tall, narrow cabinet makes it easy to integrate discreetly behind cinema screens or within architectural spaces - perfect for projects where space is limited but real infra-bass is essential.
Reliable, efficient, and engineered for installers, the Sub4-12 INFRA delivers cinematic low-end impact without oversized enclosures.
THE STORY BEHIND THE SUB 4-12 INFRA
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. It’s the hardest working element in a system, constantly pushed to its limits, and ironically, it’s also the one component no one wants to see. For cinema use, it must disappear quietly behind the screen, while still delivering earth-shaking realism far below what most systems can reproduce. When we began developing the Sub4-12 INFRA, we knew exactly what we wanted: a true infra-subwoofer capable of delivering linear, effortless energy below 20 Hz — and to do so within a footprint that fits behind a cinema screen.
In our early research, we found two recurring traits among competing products:
- They are physically very large
- They are very expensive
We decided to take a completely different approach. Instead of one huge driver, we chose four precision 12-inch drivers, working together in perfect phase alignment. In total cone area and linear excursion, this equals a massive 24-inch driver — but with far lower distortion, higher thermal power handling, and greater reliability. To further optimize output and efficiency, we employed our proven 6th-order bandpass architecture, a design principle we’ve refined over many years. This allows us to achieve extreme low-frequency performance from a surprisingly compact enclosure.
The tall, narrow cabinet was carefully engineered for maximum rigidity, minimal resonance, and seamless installation behind cinema screens or within architectural spaces. 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
- Lower cost than comparable infrasonic subs, without compromise in performance
The Sub4-12 INFRA represents the culmination of years of design evolution — where acoustic science meets installation practicality. It’s built to work harder, play deeper, and deliver an impact that feels effortless and real.
