Quadral is a German audio brand with roots in Hannover dating back to 1972. With more than 50 years of experience in hi-fi, the company has built its reputation on sound quality, speaker design and product innovation. Its history includes the launch of its own Quadral speaker brand in 1973 and the landmark TITAN model in 1981.

Today, Quadral offers passive loudspeakers and hi-fi products, alongside audio solutions designed for integration into buildings. Since joining forces with building-automation specialist Loxone in 2020, the brand has developed connected audio systems for homes, hotels, restaurants, offices and other spaces. These solutions can combine music playback with functions such as alarms, doorbell sounds and presence-based audio, managed through Loxone automation and its app.

Quadral’s Master/Client technology supports scalable installations with reduced cabling, while Loxone’s Audioserver acts as a central controller and amplifier. The brand brings together traditional loudspeaker expertise and flexible, automated audio for residential and commercial environments
