THE PQS 302

THE PQS 302

The Challenge

Our PQS 402 has been consistently popular since it was first introduced in 2006, but we found that a significant number of potential customers did not have listening rooms that were large enough to allow it to provide its best performance. For these customers we have designed the PQS 302.


The PQS 302 should not be regarded as simply a scaled down version of the PQS 402. It is an exceptional loudspeaker in its own right, with realistic and detailed three-dimensional stereo imaging, excellent dynamics and our trademark fast, deep and well-controlled bass. It goes without saying that it also offers the finesse and transparency that all German Physiks loudspeakers are famous for. Even more impressive is that it combines these attributes with an ability to produce output levels up to 112dB.


Fast and Extended Bass

The outward appearance of the PQS 302 bass system is similar to that of the PQS 402. Two bass cabinets are mounted one on top of the other and stand between a top and a bottom plate. None of these components is attached to the other using screws or any form of hard connection. Instead they are held together by a system of interlocking collars. This combined with the fact that the two cabinets have different weights, as do the top and bottom plates, means that resonances are reduced to negligible levels compared to a solid structure. In order to obtain a bass response with the required speed and extension we could not simply scale down the PQS 402 design, so we have employed a totally different approach. Each cabinet houses a single 8 inch woofer mounted on one of the forward faces, with a reflex port situated on the other. This provides a bass with the high speed necessary to match the DDD driver, whilst also producing a well controlled and balanced response down to 26Hz.


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.


The DDD driver’s very low moving mass enables it to operate linearly over an extremely wide frequency range. The PQS 302 uses two DDD drivers mounted one above the other and these cover the entire frequency range from 170Hz upwards. 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 302, like all German Physiks loudspeakers, to produce very accurate and realistic stereo images.


Another key advantage of the DDD driver is that it is omni directional, so these excellent stereo images can be enjoyed from a wide range of listening positions, unlike conventional designs, which have much smaller “sweet spots” due to the tendency of their drivers to beam the sound. This makes the PQS 302 family friendly, as several people can enjoy its superb performance at the same time.


The DDD driver’s very low moving mass provides the further benefit of exceptional impulse and phase response characteristics and allows it to reproduce both the attack of the music and provide exceptional low level detail resolution. This is essential in order to faithfully reproduce the delicate nuances and timbral characteristics of a performance and make it sound like music, rather than just good hi-fi. The driver’s excellent impulse response also ensures that the stereo image remains focussed and stable, even when the loudspeaker is reproducing complex passages at high levels.
