Ci140 sub: the ultimate home cinema experience

Using the same four bass drive units as the ci140 and working with the ATL, the subwoofer reproduces additional low frequency energy, perfect for immersive monitoring installations.

Sound quality

The PMC Ci140 Sub is designed to deliver a powerful, immersive audio experience that will bring your movies and music to life. It features four carefully tuned bass drivers to produce deep, rich bass that will fill your room with sound. The subwoofer is also designed to work seamlessly with the PMC Ci140 in-wall speaker, ensuring you get the best possible audio experience.

Advanced Transmission Line bass loading technology

The PMC Ci140 Sub uses Advance Transmission Line (ATL) bass loading technology, which uses a proprietary aerodynamic vent instead of a conventional port. The ATL design uses the bass energy in a much smarter, more efficient way than designs based on ported or sealed boxes, resulting in extended bass that sounds like a much larger speaker.

Laminair Vents

The PMC Ci140 Sub features Laminair vents which result in a smooth laminar airflow at the line’s exit. This reduces turbulence and drag, lowering resistance and increasing efficiency. The result is faster, more defined bass with accurate timing and dynamics, without unwanted air noise.
