The The50 SUB PRO PASSIVE SEALED infrasub touches unknown territory and dimensions when it comes to reproducing the deepest frequencies. At the same time manifests itself as the definitive proof of how important the infrasonic subwoofer is in serious home theater arrangements. It challenges the known limits and lays the cornerstone for a cinematic experience of superlatives. Equipped with a gigantic custom-built 50” driver powered by DSP-controlled 20.000 watts using the AIA Speaker Management technology, the The50 SUB PRO PS is hands down one of the most powerful cinema subwoofer in the world. The speed, definition and authority paired with clarity to differentiate frequencies in the single digit range are mind blowing. Due to its ultra-low resonance frequency and its sealed braced enclosure concept, this mega subwoofer delivers an extremely fast impulse response and class leading low group delay compared to any subwoofer out in the market. It’s absolutely unique and fascinating with which ease the The50 SUB PRO PS is able to reproduce the lowest frequencies literally down to 1 Hz. With each maximum stroke, the The50 SUB PRO PS moves as much air as forty standard 18" subwoofers. This incredibly massive bass power hardly ever reaches the limit. The The50 SUB PRO PS renders with high-resolution, finely structured and explosively fast. If required, with peak levels up to 140 dB and amazing 105 dB LFE reference level of sound pressure at 5 Hz in larger rooms substantiate its unique position on the market.
