Revolutionary HybridLineSource-Technology.

The HybridLineSource is a new and worldwide unique loudspeaker system developed by Harmonic Design, which reduces the needed truck space dramatically and improves the quality of a public address system to a new level of uniformity and complete absence of distortions. The HybridLineSource System is equipped with two specially designed high performance 12“ neodymium low frequency chassis and reaches already a sensitivity of 108dB in the low-mid-frequency range.

Powerful LineSource-Unit makes the Difference.

The exceedingly large-dimensioned high frequency LineSource-section consists of four 1.4“ neodymium compression drivers with a special polymer diaphragm, coupled to dedicated LineSource wave formers generating a cylindrical wave front with a vertical opening angle of 40°. Therefore the throw of a HybridLineSource-System is comparable with a LineArray. Due to the coaxial setup the horizontal coverage pattern is free of interference in the crossover area and perfectly consistent over an angle range of 100°. Double-Hangs become redundant.

Efficiency redefined

Easily Combinable.

The mechanical structure allows the use on a speaker stand or flown vertical arrays. Every loudspeaker has an integrated 3-point FastRig-rigging system where the inter element curvature can be set precisely in 5° steps from 5° to 20°.

Reliable and Audiophile.

Operation takes place with Harmonic Design system amplifiers and guarantees outstanding performance and compatibility even in the worst circumstances as well as highest efficiency in terms of power consumption, truck space and output level. Up to two loudspeakers can be connected in parallel to the Harmonic Design system amplifiers. An optional available passive phase optimized crossover allows simple and quick operation on a single system amplifier channel. The 2-way active BI AMP mode guarantees strict neutrality for maximum performance applications. An accurate prediction is possible with EASE Focus.

Sophisticated Accessories save Time and Costs.

The hd RF3 is rigging frame and stand adaptor likewise that may be used to carry a single unit on a spekaer stand with precise adjustable tilt in 1° steps from 0° – 20° as well as to fly a vertical array of up to three loudspeakers. This gives best flexibility for daily changing applications while reducing the accessories effort.

Sound with System.

There are perfectly matched hd TourSys systems comprised of top loudspeakers, subwoofers and system amplifiers as complete Allround-PA systems avaliable. Several TourSys systems may be combined to realize shows with up to 5.000 listeners.
