German Physiks – The PQS-100 Loudspeaker

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

1. 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.

2. 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.

3. 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.

4. 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.

5. 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.

6. 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.

7. 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.

8. 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.

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.
