The Unlimited Ultimate is the entry level model in the German Physiks range and is the latest version of our popular Unlimited design. It uses one DDD driver and a downward firing 8-inch woofer. It is available in a luxurious high polish polyester finish in black, white, red or yellow. A special version finished in high polish carbon fibre called the Unlimited Carbon is also available.
When the Unlimited was introduced in 2011 it set a new standard for accuracy and neutrality. In the intervening years we have steadily improved the Unlimited’s performance to ensure that this position was maintained
Less Is More
Both versions use exactly the same DDD driver as all our other models, including our Euro 250,000 flagship Gaudi, so will give the listener more than just a taste of the musical nirvana that our higher end models can provide.
The Unlimited employs a single carbon fibre DDD driver mounted on top of a compact floor standing cabinet, with a downward firing 8-inch woofer mounted in the base. This provides the famous German Physiks trademark dynamics, transparency and musicality.
Stylishly Simple Design
As well as taking great care to make the Unlimited an exceptionally good sounding loudspeaker, we also went to great pains to make it an exceptionally good looking loudspeaker. The design is intended to be both elegant and simple, so that it blends into its surroundings rather than draws attention to itself. We want the listener’s attention to be concentrated entirely on the music. This ability to blend in is enhanced by its very small footprint - just 24 cm x 24 cm (9.5" x 9.5") – so it takes up a comparatively small space on the listening room floor. Despite its modest cabinet size, the Unlimited will work well in rooms of up to about 55 square metres (580 square feet).
Tuneful Bass
One of the first things that will strike you about the Unlimited is the excellent quality of the bass, especially considering the compact size of the cabinet. The bass is deep with real weight and measurements have shown that useful bass is produced well into the 20Hz region. Importantly, the bass is also clear, articulate and in time with the rest of the audio range. It is easy to follow the bass lines and drums have an authentic impact to their transients. The correct bass balance is maintained even when listening at low levels, so you can continue to enjoy your Unlimiteds when you might otherwise have to use headphones.
The heart of all German Physiks loudspeakers is the unique omnidirectional DDD driver
The German Physiks DDD driver uses a cone made of extremely thin (0.15mm) carbon fibre. This is very light, but also very rigid. 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 the Unlimited it 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
Bending wave radiation
Modal radiation
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.
Low Resonance Cabinet Design Enhances Transparency
Colouration caused by resonances in a loudspeaker cabinet, where the cabinet itself starts to radiate sound energy, can seriously degrade the sound quality by obscuring detail. To prevent this, the Unlimited’s cabinets are constructed from heavy panels of MDF, with internal re-enforcements fitted at critical points.
As a further anti-resonance measure, a special damping material called Hawaphon® is applied to the inside of each panel. This adds mass to the panel to reduce the resonant frequency and its special internal structure very effectively converts vibration energy into heat. Hawaphon® achieves a broadband attenuation of structure-borne sound of more than 50dB: a remarkably high figure.
Finally, to damp resonances of the air within the cabinet, the whole of the inside of the cabinet is lined with a thick layer of high-density felt.
Designed for a Lifetime of Listening Pleasure
As you would expect from a German product, the quality of construction and reliability are first class. We use the same quality of parts in the Unlimited as in our reference products, where we design for a minimum life expectancy of 25 years. For this reason we have selected highly corrosion resistant V4 grade stainless steel for the DDD driver support pillars, terminal mounting plates and all the screws.
WBT nextgen™ binding posts are used to provide an excellent connection between the loudspeaker cable and the loudspeaker.
Meticulous care and attention is paid during the manufacture of the Unlimited. Prior to assembly all components and materials are subject to a rigorous inspection. We also carry out detailed inspections at each stage of the manufacturing process. We can afford to do this as we build our products by hand in small batches. After assembly the performance of each loudspeaker is measured. Then it is burnt in for at least 12 hours and measured again. Once the burn process is complete each loudspeaker is given a final detailed physical inspection before being packed.
Product Finishes
The Unlimited Ultimate loudspeaker is finished in high polish polyester black, white, red and yellow and the Unlimited Carbon is finished in high polish carbon fibre.

Hand Finished For Ultimate Quality
Because the look of our products is as important as the sound, all cabinets are hand built and finished in Germany by skilled cabinet makers for the best possible furniture grade finish.
They are built in small batches, so that they can maintain a consistently high level of quality. Nothing is rushed.
