Speaker Blumenhofer Genuin FS1

Discussing any border dynamics was the genuinely FS1 by Blumenhofer (35000 euro the couple) out of place, because his casualness spoke for itself and was simply “outstanding”, as the saying goes,.

Most boxing fans is hardly aware how wasteful common HiFi speaker to handle the performance. Why also should they worry, but Watts strong Surround receiver become cheaper and now even compact boxes in areas of sound pressure to advance, which rarely cost many users.

Since the air before a speaker membrane spoken casually rather dodging than to dance with the efficiency of common boxes usually under 1 percent remains. What energy is a disaster and only then no problems makes, as long as box and amp play without complaint.

Fortunately, our ear has a ludicrously high sensitivity, so that already sound services trigger massive sensations of a few thousandths of a Watt. In fact evidence speaks to pay more attention to efficiency, because a higher yield promises more solid sound pressure reserves, lower distortion in the side effect and increases the degrees of freedom in terms of amplifier.

Also the growing number of those who seek their audiophile salvation in Watts weak, but strong sound tube amps is one of the target of efficiency strong boxes therefore in addition to listeners with Atypically large rooms and trailers of any form of original dynamics. Which we know only rarely fully unfold their sound potential of average boxes, because they run almost constantly at the limit.

Specialists such as the Bavarian sound reinforcement professional Thomas Blumenhofer (see interview) construct therefore special high efficiency speakers with up to ten times lower watt demand.

Tinkerer Blumenhofer who hatches his pranks South of Augsburg in the Idyll of the Bavarian Alps, achieved the goal of HiFi atypical frugality at its top model by a whole bunch of measures. In the bass range, its uses as a two way system with a crossover frequency of 850 Hertz conceived a huge 16-inch drivers of the Japanese Nobel forge TAD genuinely FS 1.

The outrageously expensive, electrically how ludicrously high mechanical load cone chassis is coupled with a rectangular bass reflex tunnel and is supported by a 5 cm strong baffle out multiplex, which significantly contributes to the total weight of at least 80 kilograms.

The crossover runs as a second-order filter rests isolated from the other housing in a ground-level Chamber. The impedance of the genuinely is nominally at 8 Ohms (so rather highly resistive), FS 1 and runs remarkably good-natured. A switchable impedance correction is intended for operation with sensitive load amplifiers, irons smooth the increase in the frequency of acquisition, which can bring a sound improvement of load-sensitive amps, but does not have.

The case of in-house carpentry individually according to customer requirements rests on a three-legged tripod of metal, resulting in a highly effective decoupling of the floor. After all, 12 years bear witness to guarantee by the trust in a construction, whose pulse ratings put Bayern on 700 watts.

The highlight of the box is the Horn for MIDs and highs, its driving IC hidden deep inside has a good 6 cm large titanium diaphragm, their sound contribution flows through a sophisticated sound leadership in the space designed by the master himself. The stem ensures a drastically improved coupling, to avoid but Horn typical resonances and discoloration.

Actual frequency linearity and angle behavior does not significantly differ from the behavior of classic HiFi-boxes with small sound sources, at the same time, the compression to worlds is low.

Whoever puts it on, elicits the gem at 1 meter distance sound pressure levels above 120 decibels, civilian 90 decibels (high volume) be achieved simultaneously so casual, that the associated distortion products from the diagram coming out, because they are below the relevant limits.

The Horn conditions unusually broadband system is mounted flexibly on the larger housing and can be located on adjustment relative to the bass driver move as well as align vertically to accommodate different listening distances.

A voltage divider in the crossover reduces the exorbitant level of the Horn to approximately 6 decibels on the level of certainly not silent bass Department. By the way this decreases the effective load for the Horn drivers on such low levels that conventional high – or mid-range unit would have to be actually pale with envy.

The origin of the driver components and details of the Horn geometry will not disclose understandably Blumenhofer, where the Horn typical linearity and the good-natured dispersion definitely deserve ever highest praise.

In the tried and tested for many years listening room of the tester already various reference units stood ready to feel the horns on the tooth. Served as the interface to the boxes and related electronics for scoring the test-proven Thorens station wagon, euro consisting of from the preamplifier TEP 3800 and Mono blocks of TEM 3200 for a total of approximately 34_000. In parallel has been experimenting with other amplifiers, where the high-efficiency Horn good-natured proved striking.

So it was extremely attractive to revel strong Thorens combination in power reserves around 500 Watts, which gave the good 30 years stereoplay history so supple and homogeneous never to admire it for all involved. The long since legendary in high change “Tuva rap” stereoplay readers by the hearing test course of high-end fair 2007 know (see booklet CD may 2007), raged without noticeable compression and piek-clean around the hearing room.

Even the Horn skeptics in the Newsroom started full of lust to turn the volume. At this stage of the test, any attempt of a colleague call to fail was doomed, because to get vocally against the mind-boggling level solid horns was simply impossible.

Discussing any border dynamics was this system out of place, because his casualness spoke for itself and was simply “outstanding”, as the saying goes,.

But even more amazing was the observation that the unbridled temperament with disadvantages in spatial, tonality, or even timing was bought. Represented by delicate climes on the aforementioned booklet CD “isn’t she lovely” with Livingston Taylor, the macho tone furniture such as the innocence of the country behaved: airy, delicate and shining brightly in clear space. Fears that the huge bass driver would inferior MIDs and tone with a long-lasting, annoying humming sound, proved to be totally unfounded.

Representative for the ranks of the tubes integrated amplifier the tester fished a Cayin A-55 T (stereoplay 1/2006, 1650 euro) from the device bearing, causing the price of driving electronics on approximately one-twentieth melted together. The sound picture lost thereafter – no wonder at the cost difference — stability and also uniformity, but around 30 watts per channel were still for hearty level.

The impedance correction rather disturbing in conjunction with the Thorens cars because there clearly timing harmful, was well and helped the Cayin tube atypical firmness and stability, which is all the more obvious its velvety charm left. The whole thing with a bass power and consistency that you normally never would trust to a so delicate amp.
