THE PQS-201 MK II
The PQS-201 Mk II is a 2 way design that uses a single DDD driver coupled with a vertically firing woofer. It is intended for use in both 2 channel and high end home theatre systems. It may be mounted on the dedicated PQS stand; on shelves or directly onto the wall using an optional wall attachment kit.
The PQS-201 Mk II may be positioned against the wall. This minimises its intrusion into the room and makes it ideal for smaller listening rooms as well as home theatres.
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 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 Resonance Cabinet
To minimise resonances and cabinet talk the PQS-201 Mk II’s cabinet is constructed from heavy MDF panels with additional internal bracing to increase rigidity. Any residual cabinet talk is minimised by applying Hawaphon, a special damping material, to the inside of each panel. Hawaphon is a polymer sheet containing a matrix of small cells filled with very fine steel shot and was originally developed as an anti-surveillance measure for use in military and government buildings. It adds mass to the panel to reduce the resonant frequency and the ability of the shot in each cell to move against each other provides a very effective way of converting vibration energy into heat. Hawaphon achieves a broadband attenuation of structure-borne sound of more than 50dB. To damp resonances of the air within the cabinet, the whole of the inside of the cabinet is lined with a thick layer of high density felt.
Adjustable High Frequency Output
Jumpers on the loudspeaker’s rear panel enable the high frequency output level to be adjusted in 4 steps: -2dB, flat, +2dB and +4dB. This allows the user to easily compensate for the variations in the absorption of high frequencies that occur due to different types of furnishings and room construction. Separate input terminals are provided for the DDD driver and woofer sections of the crossover allowing the PQS 201 Mk II to be bi-wired.
Hand Finished Cabinets
The PQS-201 Mk II is available in the customer’s choice of hand matched, hard wood veneers. Cabinets supplied in our High Gloss option are coated with several layers of lacquer and then hand polished to a deep lustrous finish. This can be re-polished in the event of it receiving minor damage. The PQS stand is also available in these finishes. Please see the Finishes page for more details.
Special Order Version
A special order version of the PQS-201 Mk II is available fitted with a carbon fibre DDD driver which provides an extended upper frequency response, greater low level detail resolution and improved dynamics. The cabinet’s heavy MDF panels are reinforced with multiple layers of bi-directional, resin impregnated carbon fibre, which are applied using techniques originally developed for the aircraft industry. This produces a cabinet that is immensely rigid and strong, as well as being practically free from resonances within the audio frequency band. It also reduces the radiation of sound through the cabinet’s panels which further improves the PQS-201 Mk II’s resolution. The cabinet is coated with a multi-layer lacquer and then hand finished to a high polish. A carbon fibre version of the PQS stand is also available.
