The core scope of the project centered on complete home theater design, including detailed acoustic panel design for walls and ceilings, careful speaker selection based on room volume and listening geometry, precise speaker and subwoofer placement to achieve balanced coverage and optimal imaging, and comprehensive system schematics covering signal flow, wiring, and equipment integration. This end-to-end theater design was supported by a high-performance data network and Wi-Fi infrastructure to ensure reliable streaming and system control, KNX-based lighting control programmed for cinematic scenes and daily use, and background music in common areas using AirPlay for intuitive multi-zone audio. Through a meticulous consultancy process, KT Consultancy delivered a reference-quality home theater environment with controlled acoustics, accurate sound staging, seamless lighting integration, and a future-ready AV infrastructure designed for long-term performance and scalability.
