THE PQS-100 PLUS

THE PQS-100 PLUS

The PQS-100 Plus has been designed in response to numerous requests for a lower cost and more compact German Physiks loudspeaker. The challenge was to do this without compromising the speed, transparency and coherence that German Physiks loudspeakers are famous for. This versatile design will give excellent results in both high-end stereo and 5.1 surround systems. When used in 5.1 systems, its excellent bass response obviates the need for a sub-woofer. Its ability to produce detailed and realistic stereo images, which can be enjoyed by many listeners from a wide range of positions within the room, is especially useful in home theatre applications. It is also suitable for centre and rear channel use in multi-channel systems, where larger German Physiks models are being used for the main loudspeakers. In addition, it is 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 PQS-100 Plus uses a single carbon fibre DDD driver combined with a downward firing 6-inch woofer in a ported enclosure and is supplied with a set of custom made stands.


A Wolf in Sheep’s Clothing

The PQS-100 Plus is physically compact, so does not take up a lot of space. This makes it ideal for the smaller room. Despite its compact size, the PQS-100 Plus is capable of driving even quite large rooms to high levels. Whether used in a small or large room, it 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 provided by the PQS-100 Plus is matched by the high quality of the performance provided by its 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.


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, the DDD driver covers the range from 120Hz to 24,000Hz, so the vast majority of the audio range is covered by just one driver. The DDD driver crosses over to the woofer at 120Hz and the ear’s ability to spatially locate sounds at this frequency is far less acute than it is in the 2,500Hz to 3,000Hz region, where conventional two-way designs cross over. 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.
