The current audio exclusive P 3.1 (7800 EUR the pair) features new films and transformers, which the frequency range specified by the manufacturer to a full octave down expand.

The first transducer of our three round comes exclusively from audio and is called short and sweet P 3.1. It’s a full-range electrostats with dipole shaped dispersion pattern. With this design the sound flows equally forward as to the rear, but only very weakly to the pages.
Heating panels that cover the entire frequency range, are highly interesting for connoisseurs, because they handle impulses very quickly due to their low mass and the full drive.
But despite undeniable benefits, the design is rather rare in the living rooms to find. The dimensions are a handicap. Because the thin membranes allow only gerin-ge excursions, large areas are necessary in return. Also the required distance is back at least 1,5 m depending on the room size and hearing distance – not for everyone.
The p 3.1 the width is for moderate. The height of almost two metres may be irritating, but hardly interferes with, because the spotlights are partially transparent, and only a few centimeters deep.
The production of the films and their fixtures requires much experience. Special full-range electrostatic, covering the full frequency range and are therefore highly charged, are few and far between in the rank-and-name list of stereoplay or cost a five-figure sum.
Against this background, the towering P 3.1 is almost a bargain. It is manufactured in Germany and suggests a solid processing also and there, where one not guessed it right off the bat.
The letter “P” first and foremost reminiscent of the 1990 late developer Gerd Pütz, exclusively based on whose ideas the converter of audio.
The distances between the stator and the membrane were enlarged. This reduces the risk of hitting on that announces itself with electrostatic mostly due to energetic Crackle and crunch.
Actually climbed the retreaded Pütz converter in the listening test so deep in the basement of the frequency, that a subwoofer at no time seemed necessary. The sound appeared generally unusual bass bulging, whereby pulses in deep layers of something soft and virtual; but rhythmically they were well integrated.
The velvety, unobtrusive way moved like a red thread through the logs and was in pleasant contrast to the fine and cultivated articulation of the spotlight. As Sara k. her comparatively sparsely instrumented was “If I Could Sing Your Blues” (stereoplaybook-CD 10/10), transferred the P 3.1 the melancholic piece with an incredible grace.
Big orchestral sound samples with wild dynamic jumps joined the PAA’s successor however early on its capacity and began to distort just above the much-quoted volume – the tester had to always keep the volume control at a glance.
P 3.1 in relation to the other participants of the test results, see how the comprehensive hearing test.
The combination of audio Exclusive is open to both sides designed, he directed the sound energy in half after front and rear. Because the radiation primarily perpendicular to the membrane surface, the levels are side left and right lower.
Looking at the distribution of intensity from above, the shape of a lying eight results. In technical language, the speech is of a dipole. The marked directional effect is pronounced, the width of the listening area is low. The panels must be angled to towards the listening position. The enormous expansion of the diaphragm in a vertical directs the sound energy preferred forward, while floor and ceiling are given not so much energy. The sound is characterized less by the characteristics of the room.
The ear height is relatively uncritical due to the elongated shape. Dipole radiator, which is less high tower, respond here much more sensitive. As usual measured all converters in anechoic room. In addition, there was hearing room measurements – they capture the total radiated energy and show how couples the spotlights on the area. Was measured directly at the listening position at three meters distance.
