Round Spotlight German Physiks Limited 11

The functioning of the German Physiks limited 11 (8900 EUR the pair) is as complex as fascinating: in the lower frequencies of the emitter acts piston-shaped to higher frequencies and as oscillating waves.

The most transducers are direct spotlights which focus their energy on a relatively narrow angle. The listening area in this case is wider than 30 degrees rarely, outside it sounds dark and musty.

This focus keeps outside room properties and has more direct sound shares the result. On the other hand the strong illumination is not behavior natural tone body that usually fills stimulate a concert hall and not only partially.

Such considerations are water to the mill of the developers of round spotlights. This transducer can achieve at least horizontal full 360 degrees. Because traditional methods of measurement capture only a small angle, to proceed in more differentiated in this form of construction – details here.

One of the few perfect round radiant drivers is the DDD spotlight of the Hessian German Physiks boxes manufacture. The cone-shaped membranes can represent multiple vibration types by their bending soft texture.

The development is based on the legendary Walsh converter of the 70s that was due to several weaknesses in the meantime almost forgotten. Together with the mathematician Peter Dick, German Physiks the idea under the label “Thick dipole driver” (DDD) has modernised and refined. The transducer in Germany with membranes are manufactured from titanium foil or carbon fibers.

The operation is as complex as fascinating: in the lower frequencies of the emitter acts piston-shaped to higher frequencies and as oscillating waves. Through the Division of labour and the completely open design is emitted horizontally with an angle of 360 degrees – over the entire listening area. The drive accomplished as at piston spotlights a voice coil, which is centered in the field of a permanent magnet.

Basically the combination converter can play also bass, but only with low levels, suggesting a separate driver support. Of limited 11, the latest model of the emerging company, a conventional woofer is installed in the socket, which effectively relieves the DDD Spotlight exceeding 200 Hertz. The long-throw woofer the exotic tipped pillar helped a very adult bass Foundation, with sound largely seamless integration to the DDD driver. Representing worked right off the bat, and all music styles incredibly lifelike, the spotlights themselves were completely in the background.

Sara k. (music tips in the image gallery) seemed to float – as an extra portable speaker for the voice would be responsible like an imaginary statue in front of the jury. The directional definition reminded of good coaxial systems, depth better at not equal.

The combination of P 3.1 audio exclusive worked in direct comparison with the German Physics dynamically less informational and produced a much smaller area.

But the race was far from over. Because even the jamo waited outside the door.

The form itself and the completely open construction result an illumination of 360 degrees in the horizontal plane, no matter at what frequency. The DDD spotlights processed 11 over seven (!) in the limited Octaves with constant acoustic Centre. The usual angles on will have no effect, the listening position plays hardly any role. Since hearing distance and levels correlate less than usual, left and right sound source must have not the same distance from the listening position. Only a certain distance from the wall is necessary to arrive the room shares not too early. A good meter would be the lower limit, in larger rooms according to more.

The DDD converter is so far theoretical ideal of compact and broadband point sound source as close as currently no other system. The frequency linearity is at the level of conventional systems, the angular behavior is substantially better. Within the frequency range, 30 kHz are achieved at full 360 degrees. The Watts requirement however is quite high, and several DDD are required for large boxes.
