The HRS-130 loudspeaker is a higher performance version of our popular HRS-120. Not only have significant improvements been made to the sound quality, but the cabinet has been restyled to give a smoother look, enabling the HRS-130 to blend more easily in to the room. The improved look is enhanced by a new, luxurious high-polish polyester finish, which is available in black or white.

The HRS-130 Loudspeaker uses a single carbon fibre German Physiks DDD driver mounted on top of a slim, octagonal, floor standing cabinet, with a downward firing 10-inch woofer set in its base

Exceptional Driver Integration

The crossover in the HRS-130 is developed from the one used in the Borderland Mk IV: its larger stable mate. This provides exceptional integration of the DDD driver and woofer, so that they work seamlessly together to create a detailed, three-dimensional stereo image that immerses you in the music. The transparency of the DDD driver opens a new window on to your music collection, by helping to reveal fine detail and ambience information that you would normally only expect to hear at a live performance.

 Improved Resolution and Dynamics 

The HRS-130 has a new crossover derived from the one in our best selling Borderland  Mk IV. It provides improved resolution and dynamics, making it even easier to follow the various threads in a performance, even at high levels.

This makes listening a truly involving experience.

 Most important of all, the DDD driver’s exceptional transparency better allows you to experience the emotion that is the essence of a good musical performance.

Well Controlled and Extended Bass 

The bass driver is located at the bottom of the cabinet and works in a “sealed” enclosure. This enclosure is linked via a small opening to a smaller cavity located at the top of the cabinet. This cavity acts as a Helmholtz Resonator and is tuned to the resonant frequency of the main bass enclosure and ensures a smoother bass response.

The HRS-130 uses the same 10-inch bass driver as our much more expensive PQS-402. This provides deep and well defined bass with excellent control. The integration of the bass with the rest of the frequency range is exceptional, allowing you to immerse yourself in the music without the feeling that you are listening to several different drivers.

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 HRS-130 it covers the range from 220Hz 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.

Quick and Easy to Set Up

The DDD driver’s omnidirectional radiation pattern and wide operating frequency range make the HRS-130 less critical of its position in the room than conventional loudspeakers, so it is very quick and easy to set up. In addition, because the HRS-130 is omnidirectional, there is no toe-in adjustment to worry about. Last but not least, with a cabinet footprint of only 325mm x 325mm (12.8” x 12.8”), the HRS-130 is easy to fit into even a modest sized room. Don’t let this deceive you though, as the HRS-130 will drive rooms up to 75 square metres (792 sq ft) in size.

Bi-wire or Bi-amp

The HRS-130 is fitted with two sets of high quality WBT nextgen™ loudspeaker terminals. This allows the HRS-130 to be bi-wired or bi-amped. High quality jumpers are supplied to enable the HRS-130 to be used with just one set of loudspeaker cables.

Adjustable High Frequency Output

Jumpers on the loudspeaker’s rear panel allow the high frequency output level to be adjusted in 4 steps: -2dB, flat, +2dB and +4dB, enabling the user to easily compensate for the variations in the absorption of high frequencies that can occur due to different types of furnishings and room construction.

Low Resonance Cabinet Design Enhances Transparency 

Colouration caused by resonances in a loudspeaker cabinet, where the cabinet itself starts to radiate sound energy, can seriously degrade the sound quality by obscuring detail. To counter this, the HRS-130, like our more expensive Borderland MK IV, uses an octagonal cross-section cabinet. The panels on this cabinet are smaller and stiffer than those of an equivalent size square section cabinet would be. Critically placed internal bracing further increases rigidity.

As a further anti-resonance measure, a special damping material called Hawaphon® is applied to the inside of each panel. This adds mass to the panel to reduce the resonant frequency and its special internal structure very effectively converts vibration energy into heat. Hawaphon® achieves a broadband attenuation of structure-borne sound of more than 50dB: a remarkably high figure

Finally, 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.

Designed for a Lifetime of Listening Pleasure

As you would expect from a German product, the quality of construction and reliability are first class. We use the same quality of parts in the HRS-130 as in our reference products, where we design for a minimum life expectancy of 25 years. For this reason we have selected highly corrosion resistant V4 grade stainless steel for the DDD driver support pillars, terminal mounting plates and all the screws.

Meticulous care and attention is paid during the manufacture of the HRS-130. Prior to assembly all components and materials are subject to a rigorous inspection. We also carry out detailed inspections at each stage of the manufacturing process.We can afford to do this as we build our products by hand in small batches. After assembly, the performance of each loudspeaker is measured. Then it is burnt in for at least 12 hours and measured again. Once the burn process is complete each loudspeaker is given a final detailed physical inspection before being packed.

Product Finishes

The standard finish for the HRS-130 loudspeaker is high-polish polyester in black or white. Other finishes are available to special order. These include satin and high-polish veneers; satin and high-polish paint and carbon fibre.

Hand Finished For Ultimate Quality

Because the look of our products is as important as the sound, all cabinets are hand built and finished in Germany by skilled cabinet makers for the best possible furniture grade finish.

They are built in small batches, so that they can maintain a consistently high level of quality. Nothing is rushed.
