Harmonic Design: a lot of technology, much more sound, less bulk

10 September 2026

We are highlighting this interesting interview by Dave Rat with Tim Maier, Sales Manager at Harmonic Design: an opportunity to get to know the German brand more closely and some of the solutions that best tell the story of its design philosophy, technology, and approach to professional audio.

Compactness, efficiency, and control are not simply product features: they are the starting point of the Harmonic Design philosophy.

It starts with the new hd BS10 BatterySpeakerSystem, a portable battery-powered system that goes far beyond the concept of a standalone loudspeaker. It can use common professional 18 V batteries, integrates a 6-channel mixer, DSP, and remote control via app, and can become the heart of a more elaborate PA system, thanks to dedicated outputs for loudspeakers and subwoofers.

hd BS10 - 2 way active battery powered portable loudspeaker, 1000 W built in hd SpaceAMP technology with FIR DSP, 10" LF + 1" HF, 90° x 60° dispersion, 4" touch LCD, 2 x 18 - 40 V universal battery inserts, 2 x 9,5" rackmount slots, 4 x analog inputs, BT-receiver, Wi-Fi control

The tour continues through the technologies developed by Harmonic Design to achieve increasingly precise sound dispersion: coaxial loudspeakers, column systems with cardioid configuration options, and beamforming solutions designed to accurately control sound distribution.

When even greater performance is required, the professional amplification hd QT12-ETH and the HybridLineSource technology of the hd HLS series come into play. Here the Harmonic Design philosophy becomes especially clear: concentrating high efficiency, directivity, and sound pressure in extremely compact systems.

The video shows how a single HybridLineSource system can achieve performance and coverage normally associated with much larger line array configurations: fewer elements, less bulk, greater ease of management.

A design approach that Harmonic Design summarizes well in its own engineering: getting the most out of every component, without unnecessary compromises.
