More information about the PQS-100

The PQS-100 is a compact loudspeaker intended for use as the side and rear channels in high-end home theatre systems, where larger German Physiks models are being used for the main channels and where its exceptional resolution and dynamics will greatly add to the enjoyment of movies and music videos.

Stylishly Compact: The PQS-100
Its single carbon fibre DDD driver produces detailed and realistic stereo images, which can be enjoyed by many listeners from a wide range of positions within the room. This avoids the “one seat sweet spot” stereo image that most conventional loudspeakers produce.
The PQS-100 is designed to be wall-mounted in order to minimise its intrusion into the room and so save space. Due to its compact size, it is also well suited for use in galleries, shops and other public places where very high quality sound is required and the sound source must be unobtrusive.

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 PQS-100 it covers the range from 120Hz up to 24kHz – more than 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.

The DDD driver’s omnidirectional radiation characteristic and its very wide operating range, together with several other key features give the following important advantages to all German Physiks designs and is what sets them apart

Exceptionally coherent and natural sound
This is due to the DDD driver’s 7 octave plus operating range. This is very difficult to achieve when such a wide range is split over two or more different types of driver, which are in different positions on the loudspeaker’s cabinet.

This wide operating range also eliminates the crossover point in the mid-range that loudspeakers using pistonic drivers must have. This is where our hearing is most sensitive, so removing anything that might cause level or phase errors from here will improve transparency.

Realistic stereo images more like those you experience in the concert hall
This is because the DDD driver’s omnidirectional radiation characteristic creates an enveloping sound field like that in the hall, rather than beaming the sound at you as conventional drivers do. This way the PQS-100 is able to recreate a more natural rendition of the original stereo image. This has excellent depth and focus, but without the overly sharp image definition that some hi-fi loudspeakers produce and which you will rarely if ever hear at a live performance.

Stereo imaging enjoyable in almost all positions in the room
This is achieved whilst also maintaining an even tonal balance, much like at a live performance: again due to the DDD driver’s omnidirectional radiation pattern. This gives more flexibility in where you sit and allows several people to enjoy a good sound together. This is useful in home theatre systems.

As you are not restricted to a small “sweet-spot” in order to hear the best sound, the PQS-100 provides a more relaxed listening experience. This is especially noticeable when you listen for long periods.

Exceptional dynamics
The DDD driver’s very low moving mass, less than 3 grams, allows German Physiks loudspeakers to recreate both the attack of the music and resolve low level detail very accurately. This is essential in order to faithfully reproduce the delicate nuances of a performance and make it sound like music, rather than just good hi-fi. The resultant transparency is maintained even on complex high-level passages.

Accurate portrayal of musical instruments’ tonal characteristics
This is because the DDD driver is phase linear across its operating range. This together with the excellent dynamic response, enables the PQS-100 to reproduce percussion with startling reality. Voices have a clarity and purity that can be breath taking, with all the elements of the vocal sound correctly located in space and with no undue emphasis. The hardness you often hear with conventional tweeters is eliminated and you get a greater sense of hearing a live musician.

Quick and easy to set up
As they are omnidirectional, German Physiks loudspeakers are less sensitive to room position than conventional designs and there is no toe-in adjustment to worry about.

The DDD driver is less likely to excite cabinet vibrations
Due to its very low moving mass and the way that it is mounted, the DDD driver puts less energy into the cabinet than an equivalent conventional driver. This reduces cabinet resonances and improves transparency.

Physically extremely rugged
The DDD driver can withstand abuse that will destroy most other drivers. Thisis illustrated in the video below. We don’t advise our customers to try this, just in case they are having an unlucky day.

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. The PQS-100 solves this problem by having to all intents and purposes no cabinet.

The top, bottom and back plates are machined from single pieces of solid MDF and are inherently very stiff and non-resonant.

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 PQS-100 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.

Meticulous care and attention is paid during the manufacture of the PQS-100. 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 PQS-100 loudspeaker is attractively finished in a two tone black and grey Nextel colour scheme that will look at home in almost any surroundings.

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.
