Boxe German Physiks PQS-100 Plus

Overview

 
The PQS-100 Plus uses a single carbon fibre DDD driver combined with a downward firing 6-inch woofer. It is physically compact, making it ideal for stereo systems in smaller rooms. It can also be used in 5.1 systems where its excellent bass response obviates the need for a sub-woofer.
 

 
THE PQS-100 Plus is a small, but highly versatile loudspeaker that can offer excellent sound in a wide range of applications.
 

Versatility With Musicality

 
Like all German Physiks loudspeakers, PQS-100 Plus can produce detailed and realistic stereo images, which can be enjoyed by many listeners from a wide range of positions within the room. This is especially useful in home theatre applications. This also makes the PQS-100 Plus 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.
 
Despite its compact size, the PQS-100 Plus produces fast, clean and agile bass, which makes the listener think that a much larger loudspeaker is being played. The high quality of the bass is matched by the performance provided by the DDD driver. This gives the excellent speed, dynamics and resolution that German Physiks loudspeakers are famous for and helps to produce the sense of reality that is the essence of a musical performance.
 

 

Versatile Mounting Options

The PQS-100 Plus may either be mounted on the optional PQS-Plus stands, or attached directly on to the wall. The latter is especially convenient when the PQS-100 Plus is used in 5.1 systems.
 

 

Excellent Driver Integration

 
A problem with multi-way loudspeakers is how to integrate the drivers so that the listener is not conscious of different parts of the audio range coming from different parts of the loudspeaker. The PQS-100 Plus solves this problem in three ways. Firstly, its carbon fibre DDD driver covers the range from 120Hz to 24,000Hz, so the vast majority of the audio range is covered by just one driver. Secondly, the woofer is physically located very close to the DDD driver, which makes the two drivers appear as one source. Thirdly, by making the woofer fire downwards, its radiation pattern more closely matches the omnidirectional pattern of the DDD driver.
 

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. This is explained in more detail here.
