Product infoThe modular horn systemHere I wanted the 16 cmFostexBroadbands of the Sigma series -FE 168E sigma- Use optimally and modularly expandable from 1 to 3-way.At the same time, Fostex coincidentally launched another 16 broadband as a limited special model, theFE163EN-S. As it quickly became apparent, this exclusive model also worked excellently in theBK 166Bass horn and even without correction elements.TheFE 168 E Sigmaequipped with a special blocking circle plays flawlessly and without discoloration over the entire area up to the heights. Particularly good fundamental and midrange due to the unique computer-optimized and stiffened membrane.In the second step you can use the excellent ring radiatorFostex T90 Aadd and then expand the original broadband project into a 2-way system. As a result, the tweeter area becomes significantly more airy and silky, and the spatial image becomes even more stable when the tweeter emits in phase with the broadband chassis. This can be done optimally by moving theT 90 Ahappen on the stand above the broadband chassis.In the third and most complex expansion step (HOBBYHIFI 6/2012) I then donated a wooden radial horn to the backloaded hornH 400with theFostexFull range driverD 1405as a midrange speaker for the range between 700 and 5000 Hz. This addition finally leads to a dramatic improvement and undirected extremely wide horizontal radiation of the middle pitches. Voices gain tremendous naturalness, openness and directness. A wide stage opens up.Such a 3-way horn system is not easy to tune. So Mr. Timmermanns from HOBBYHIFI criticized some small mistakes regarding the crossover. These were then immediately corrected in a further fine-tuning (Modification MK II). At the same time, the low-frequency range was expanded – accompanied by a reduction in the overall sound pressure of the speaker. The bass range is now strong and very dry even when set up away from the wall! Amplifiers of all kinds (not just tube amplifiers) now get along well with the speaker.TheBK 166/3offers full unlimited horn dynamics up to far over the entire listening range of 40 – 30000 Hz and the feeling of a world-class horn loudspeaker with somewhat reduced sound pressure, is therefore not designed for “very loud listeners” and feels most comfortable in small to medium-sized listening rooms.The slightly higher total price is more than justified for this work of art!
Experience report of a customer with the limited broadband FE 163 EN-S + FT 96 H in the BK 166:
Shortly after the publication of the bass horn BK 166 from HH article 4/12 I went to Saarbrcken in mid-2012 to hear the horns live. Since I have only heard mediocre tuned bass horns in the self-construction fair, I was already excited before Allen things to Fostex BB FE163EN-S. When I arrived at Mr. Damde’s shop, a crowded listening room awaited me, but it was pleasantly different from the sparkling hifi shops in my home town. In preparation for my pre-registration, Mr. Damde let the bass horns “warm up”. Even from a distance, pleasant classical music spread in the listening room. Before I started listening, I asked which electronics were connected. Mr. Damde is absolutely down-to-earth and beyond all star doors: “Expensive amplifiers are not absolutely necessary, even with small ones they get very good sound. And I want to show you the boxes with simple amplifiers”. One thinks to hear subliminally how much eyewashing is done with commercial hi-fi competent and even more so with loudspeakers.
First the boxes played solo, ie without super tweeters. Mr. Damde plugged in the Fostex FT96H super tweeter using a freely wired crossover. The difference lies mainly in the spatial performance and was immediately audible, which is why I decided on this version. Without hesitation and with a smile on his face, he left the store with the limited BB. This happened a year ago …
… and today they are in my living room. Instead of the BK166 housing, the BBs were installed in a housing according to the Fostex specification with an additional tweeter attachment, ie I did not put the HH on top but in an approx. 9 cm high extra chamber installed. This made the horn 105 cm high. I also chamfered the BB 5 mm deep into the front. The tweeter is set back 19 mm. Mr. Damde has developed a soft circuit for the super tweeter.
I connected the boxes with an 8-core telephone cable, 11.5 meters long per box (so that the community has something to complain about). A listening path modified by Aaron preamp and power amplifier serves as amplifier.
And what came out? I have rarely heard such a sound. It is the directness that immediately captivates the bass horn. Drums and percussion instruments come with force and precision even though the horn only goes down to 50 Hz. You can feel the broken membrane. It has class and captivates you.
The music separates perfectly from the speakers and floats in the room. If you close your eyes, you think you have headphones on. The sound is distributed almost everywhere in the room. My son said that sounds like surround. But the hardest critic to convince is the woman. When she saw the size of the new one, she was slightly shocked. But the first notes made her listen (for the first time after 3 pairs of boxes in my past). When I showed her, she was about 5 meters to the side in the L-shaped living room. Sober, she said only “but they sound really good”. Beyond the hi-fi triangle, the boxes fill my 55 square meters of living space. Music seems to be everywhere. The musical stage is easily mapped in front of the boxes. The room is one of the best I have ever heard. Music also spreads beyond the outer boundaries of the boxes. Fantastic. A courageous turn of the volume control up to the neighborhood of incompatible volume is possible, but interestingly, even quiet or medium-loud listening is very pleasant. Sometimes I prefer the quieter setting – simply because it sounds more relaxed. A property that I only heard with very expensive speakers.
Then came an indirect confirmation today. At the hi-fi dealer I listened to the Piega Coax 30. Price approx. The bass horn plays so much more directly. The sound wave seems to be immediately with the listener (very nice Friedemann’s Bao Lan from the aquamarine). Torn guitar sides have the typical gripping noises that I have not heard in other boxes (Friend and Fellow: Clock).
In comparison, the Piega’s sounded almost spongy in the bass and flat. The boxes dissolve very nicely, without question, but they have a tendency to be hard in the heights and in female voices. If you compare the electronics at Art of Sound from just a tenth of the price, you start to ponder. You immerse yourself in the music and this is the fascination of this type of box. It doesn’t matter whether the horn goes up to 40 or 30 Hz. The quality of how percussion instruments are reproduced is so striking and realistic that the music comes to the fore and not the loudspeaker box.Albert K
