Boxe German Physiks HRS-130
Boxe German Physiks HRS-130
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 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 Unlimited it covers the range from 200Hz up to 24kHz – almost 7 octaves.
This extremely wide range is achieved by the use of 3 modes of radiation
Bending wave 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. This is explained in more detail here.
