Since its founding in 1980, Harmonic Design® (called hd) has stood for the development, production and sale of innovative loudspeaker systems and acoustic services. Our customers are musicians, professional PA systems rental companies, installation companies, hi-fi companies and industrial companies.
As a Swabian family business, we focus on quality that inspires. Each product is developed entirely in-house and assembled by hand by our highly skilled technicians. This is how we create, without exception, valuable and durable quality products for simply harmonic sound.
