German Physiks

Unique Omni-Directional Loudspeakers

Audioform focus on two models in the German Physiks range. The Unlimited Ultimate & HRS-130  All German Physiks speakers use the same DDD driver which creates an enveloping sound field in the listener’s room that more closely mimics that found in live music venues and concert halls.  This provides a more natural recreation of the original musical performance and a more life-like enjoyable listening experience. 

The crossover in the HRS-130 is set at 220Hz allowing the full mid and treble frequencies to be delivered by the DDD driver. This provides exceptional integration of the of the DDD driver and woofer, so that they work seamlessly together to create a detailed, three-dimensional stereo image that immerses you in the music.


The transparency of the DDD driver opens a new window on to your music collection, by helping to reveal fine detail and ambience information that you would normally only expect to hear at a live performance.


Key features of the speakers are 

- Exceptionally coherent and natural sound

- Realistic stereo images more like those you experience in the concert hall

- Stereo imaging enjoyable in almost all positions in the room

- Exceptional dynamics

- Accurate portrayal of musical instruments’ tonal characteristics

The heart of all German Physiks loudspeakers is the unique Omnidirectional DDD driver.

The original version of the DDD driver used a cone made from 0.025mm thick titanium foil. Whilst providing an excellent sonic performance, it was also very fragile and easily damaged. The current version of the DDD driver uses a cone made from 0.15 mm thick carbon fibre. This version has a wider frequency range and it is also considerably more rugged. Each driver is hand-built by a skilled technician in our factory in Germany.


This is a painstaking process that takes 6 hours. After assembly, each driver undergoes a series of rigorous tests. It is then subject to a 96 hour pre-aging process, playing specially selected music at high level. Finally, it is retested and put together with another driver to form a matched pair.

The DDD driver has two key distinguishing features

1. It is omnidirectional, meaning that it radiates the sound evenly around it.
2. It has an exceptionally wide operating range. In most models it typically covers the range from 200Hz up to 24kHz – almost 7 octaves .   


This extremely wide range is achieved by the use of 3 modes of radiation

Pistonic radiation
Where the driver cone moves back and forward like the piston in a car engine.

Bending wave radiation
Where the driver cone flexes and a wave is made to travel down its side.

Modal radiation
Where the driver cone is allowed to go into break up and areas of excitation are created on the cone surface. In a simplified form we can think of these areas as looking like the pattern of waves we see when a stone is dropped into a pool of water. In reality the patterns will be more complex and they will change with frequency.

By comparison, most loudspeakers use drivers that only use pistonic radiation. These have a much narrower operating range and as the frequency rises, they tend to concentrate their energy into a progressively narrowing beam.
