German Physiks HRS 120 in the Test

German Physiks makes its unique DDD converter slightly less exclusive: thanks to meaningful austerity measures, the piñata cost just half. In the test, they must show what they do.

The German Physiks HRS 120 is based on the larger “borderland” and w/as fu? r spaces developed 40 square metres up to. She cost 13 €600 until recently, is now but thanks to austerity? r to have 7000 euro.

With only two paint variants, the theme selection remains now u? berschaubar, also, the box will be distributed exclusively in Germany. Also works the graceful octagonal pillar of sound with the gu? nstigeren Carbon version of the DDD driver. Gegenu? ber the titanium version the carbon fiber is more robust and faster, says owner Holger Mu? ller. Unlike traditional chassis at the flared trumpet-shaped membrane is kopfu? ber hung up and will be back after the pulse of the centering spider towards the head plate? ckgefu? hrt.

Construction and interior design

The enclosed octagonal housing the German Physiks HRS 120 consists of various, partly cement-MDF varieties. In addition, rotating multiplex rings stiffen the walls. Accesses the DDD converter on the top volume. The lower volume, a Helmholtz Resonator works disturbing ROAR remains inevitably caused by the longitudinal resonance in larger volumes.

All walls are a highly compressed, 1 cm strong felt bonded to achieve a uniform insulation and damping. Another insulating layer consists of the so-called Hawaphon. The here included cell matrix of steel balls converts vibrations into heat, which achieves up to 50 DB a sound insulation value. In the base, you will find the eight outlets fu? r the Downfire-bass.

From the piston to the bending motion

German Physiks uses the rare principle of bending waves, where the DDD converter is a mixed variation and changes only with increasing frequency by a piston-like in a bending motion.

Imagine you can be with the beru? famous stone’s throw into the water: the wave generated by the impulse is evenly spreading in all directions. This wave energy once dry, it takes a little while; however the vibration therefore not immediately again reassured in the waterfall chart. It has to do little but warm with the untamed resonances of radiating in piston-shaped chassis. Reflections on the headstock are indeed included in the radiation, said Mu? ller. This creates additional acoustic energy in the high frequency range.

Wide range of

MU? Barcelona “Thick dipole driver” is able to cover a very wide frequency range in the Unicorn, he is running without Bassunterstu? support. In the HRS 120 cleared him a 25 bass in the tried and tested principle of Downfire; Underdru the longitudinal resonance in the elongated body? tournament a Helmholtz resonator. Care can be Holger Mu? ller in the Electronics Show. So, all switches before mounting electricity charged and subsequently adapted the component values.

Great harmony

Although the Centre high-frequency unit a scarce meters u? ber the bass driver is installed, plays the whole thing from the beginning u? surprisingly seamlessly together. The shamisen world musician Yoshida brothers combine Japanese culture instruments with neo orchestral rock arrangements. In the brilliant start the 120 HRS stomps the deep Japanese drums loosely and punchy from the enclosure, while the electric bass may Growl properly: it turns on.

In addition the experience a wide figure, although not everything is centimetre placed in the, but a realistic space. However, the attack of the three-stringed shamisen requires a strong dose energy in terms of presence. Here the DDD converter shows his flexibility and brings the delicate guitar instrument clearly forward.

Space-hearing

The installation requires a little care. After all, there’s an intense interaction with the walls of the room due to the high proportion of diffuse sound. After a bit of site optimization and verku? houses top distance sings Johnny Cashs bru? indigenous voice on “American V” with more substance and intimacy. The special feature of the German Physiks: You can stand up and walk around once to the box; the recording works just as well in the other direction. Free-standing installation is not only allowed, but is part of the concept.

Although a precise, accurate room is not the great strength of the DDD-Converter: with Live shots , he shows his true talents. Monty Alexanders “The Good Life” is apparently in the stereoplay listening room, and Bach’s Ouvertu? ren reproduced here with a wholeheartedly the Freiburg Baroque orchestra? Ment, which is surprisingly close to the real concert event.

The circular beam principle is worth a try anyway. Especially classical and jazz fans should take an ear. On the basis of the nominal low efficiency, the editorial recommends but powerful amplifier. In the stereoplay reference power amplifier, Ayre Xia plays of DDD? of course absolutely loose.

But is also a small amplifier? HAL In the usually relatively Uncontrolled living the u install? room reflections until to 6 decibels additional sound energy, which improves the acoustic efficiency of literal. Then, even the not so strong, but terrific-sounding Creek destiny amplifier – a really round thing fits!
