The 
DDD Driver
The DDD driver is used on all German Physiks loudspeakers and the same quality of driver is used on all models from our entry level product, to the top of the range Gaudi. This revolutionary driver gives the same very important advantages to all German Physiks designs and is what sets them apart from our competitors.
Its very low moving mass enables it to operate linearly over an extremely wide frequency range. The carbon fibre DDD driver used on the PQS-100 Centre covers the entire range from 90Hz to 24,000Hz. In a conventional design, this range would be covered by two or even three different types of driver and most importantly there would be a cross over point in the mid-range, the area where our hearing is most sensitive. The DDD driver’s wide operating range allows this vital region to be kept free from the level and phase anomalies that multiple drivers and a necessarily more complex crossover would create. This enables the PQS-100 Centre, like all German Physiks loudspeakers, to produce very accurate and realistic stereo images.
The DDD driver is omnidirectional, so the excellent stereo images it produces can be enjoyed from a wide range of listening positions in the room. This gives more flexibility in where you position the loudspeaker and where you sit. It is also an ideal property in a loudspeaker intended for use in home theatre systems, where there may be several listeners.
The drivers in a conventional loudspeaker beam the sound, rather than radiating it evenly around the loudspeaker. This beaming effect becomes more pronounced as the frequency increases. Consequently, you generally only obtain the correct tonal balance when seated in a narrow range of positions in the room. 
By contrast, the DDD driver’s omnidirectional radiation pattern ensures that the tonal balance of the music is much more even throughout the room. Modern movie soundtracks are very detailed. In many cases not only will there be a large orchestra that on its own covers a very wide frequency and dynamic range, but there will be complex sound effects sections with a large number of elements, as well as several voice tracks. The DDD driver’s exceptional speed and low distortion enable it to clearly resolve all the elements in even the most complex soundtrack and so provide a much more enjoyable and exciting viewing experience.
The DDD driver is phase linear across its operating range ensuring that the timbral character of each musical instrument is reproduced with great accuracy. This also makes sound effects more believable and is particularly noticeable on complex and very dynamic effects.
More information on the DDD driver, its development and advantages may be found on the Technology page of this web site.
Low Cabinet Colouration
The PQS-100 Centre solves the problem of cabinet colouration 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.
Attractively Finished Cabinets
The PQS-100 Centre is attractively finished in a two tone black and grey Nextel colour scheme that will look at home in almost any surroundings.
