Klipschhorn K-347

Country: United States of America (USA) Manufacturer/Brand: Klipsch Audio Technologies; USA
Year: 1946 ?? Type: Loudspeaker (or headphone)Loudspeaker of any kind.
Anfangszeit und erste Rundfunkzeit: Kopfhörer, die man bald mechanisch durch Trichter oder Relais (Brown) verstärkt, um darauf Trichterlautsprecher und bald auch magnetische Systeme zu verwenden. Ab 1932 gibt es bessere magnetische LS, sog. Freischwinger (nicht zuvor!) - bald auch niederohmige dynamische Systeme, die sich dann durchsetzten. Siehe Radios von gestern Seiten 34, 53, 54, 60ff, 70, 83, 84, 312, 328ff, 367.

Quand je faisait la collection je ne savais rien de ces dates des gammes d`ondes - ou bien l`apparaeil n`est pas un récepteur.
Beim Erfassen dieses Feldes waren mir die Wellenbereiche nicht bekannt - oder der Apparat ist kein Empfänger.
Power type and voltage No Power needed
www.radiomuseum.org Model: Klipschhorn K-347 Material Wooden caseWooden case. Most radios have a wooden cabinet until the WW2. Caisse en bois.
Die meisten Heim-Rundfunkempfänger führen von Beginn an bis etwa Ende 60er Jahre Holz als Gehäuse. Auch frühe Reiseempfänger zeigen Holz (speziell in den 20er Jahren) oder Holz mit Stoffüberzug etc.
Dimensions (WHD) 28.2 x 52 x 28.2 inch / 716 x 1321 x 716 mm
Notes Floor standing, fully horn-loaded, very high efficient, three way speaker system. Bass section is folded-horn structure utilizing adiacent walls as horn extension. Response 23 to 17.000Hz within 5dB. 400 and 6.000Hz crossover frequencies. 16 ohms impedance. Several finishes available. A 'classic' speaker system, one of the very best, in production for years and years.

This model was suggested by Ernst Erb.

Tissue is made elswhere, otherwise the Loudspeaker is an original factory finnished product.Stoffbespannung ist separat erfolgt, Brett oben gehört nicht zum Lautsprecher, der sonst Fabrikoriginal ist und kein Selbstbaukit.

Detail: The wall enlarges the subwoofer system - the by far biggest (lower) part of the 3-way-system.

When I posted my first Forum entry on Klipsch speaker systems, I was just relying on my memories. From the late sixties to the early seventies I owned several models, Heresy, Cornwall, La Scala and evaluated the Belle and the Klipschorn; eventually I retained a couple of La Scala, which still today are my favorite speaker enclosures. Recently I have found data about the Klipsch production of that time in some Hi-Fi magazines, including a 1972 Stereo Directory and Buying Guide. Then I loaded new entries to cover the five base models built at the time by Klipsch. But the incomparable sound of a couple of Klipsch enclosures, when reproducing the vibrating notes of a grand piano or the loud bass of a pipe organ, cannot be described in few words of notes to the model. I remember that the Klipsch dealer also distributed top speakers from well-known manufacturers: Electro Voice, Altec, JBL, Harman Kardon, Empire. Well, after having enjoyed the deep, vibrating organ sound in the introduction of 'Also sprach Zarathustra' coming out from a couple of Cornwall or of Belle Klipsch, any other speaker appeared as sounding flat and colorless. In the past I read several technical articles from Paul W. Klipsch. Unfortunately I lost them and today I can just rely upon the Radiotron Designer's Handbook for information about the horn loudspeakers. Two major sources of distortion in standard speaker systems are the non-linearity of the magnetic flux linked with the voice coil over its travel and the reduced compliance of the cone suspension, when large displacements from the rest position are reached. Klipsch found that the distortion could be dramatically reduced, limiting the displacement of the moving coil and of the cone or, in other words, using horn speakers. Horns act as sound amplifiers: a relatively small vibration of the driving unit at the throat of the horn gives a loud sound coming out from its mouth. Moreover the horn speakers have very high efficiency, when compared with any other enclosures: few watts of electrical power give a full orchestra in a room, with plenty of power reservoir for handling any super-imposed bass drum beat. To give the same sound pressure level an infinite baffle could require up to one hundred times more electrical power: amplifier and speakers may be driven well into saturation! The horn principle was not new, but Paul Klipsch committed his life to design and build the most perfect speaker systems ever made, based upon horn units all over their bandwidth. The first Klipschorn production dates back to 1946 and the model is still built today, over than sixty years later, with only minor changes. The Klipschorn, with its nearly flat response down to about 30Hz and its very high efficiency, about 50%, is the most perfect speaker system ever built for home. Klipschorn uses a 15 inches speaker as driver for the bass horn; the sound is radiated from the enclosure toward two perpendicular walls of the room, integral parts of the horn itself. Around 1963, Paul Klipsch introduced a fully self-contained horn enclosure, La Scala, which could be placed anywhere in the room, not just in a corner. Few years later Klipsch introduced the Belle, a finished version of La Scala. Both La Scala and the Belle used the same speaker set of the Klipschorn, giving a similar efficiency and slightly reduced response at very low frequencies. Of course two Klipschorn enclosures were not intended for small flats. Large halls with three walls and two corners free from obstacles were required to host them, as remarked by Klipsch in the following advertising, "You already own important parts of a fine stereo system: your room corners": forumdata/users/6435/klipsch/adva.jpg Also La Scala and the Belle asked for
More... klipsch: Klipschhorn La Scala (25.03.2007) Emilio CiardielloHits: 394 Replies: 0 Klipschorn and La Scala were two different models built by Paul Klipsch. The main difference, apart their dimensions and their price, was that the Klipschorn used the walls of the room as integral part of the bass horn unit, while in the La Scala, which was the unfinished version of the Belle Klipsch, the bass horn was self contained. Two Klipschorn speaker units required a custom designed house, to host them: two corners and three walls of solid concrete, free from obstacles. The basses were radiated toward the walls and here reflected to the room center. The Belle Klipsch, and the unfinished La Scala, had wooden walls on the sides, so to complete the folded horn driver in the cabinet itself and the basses are radiated to the front. In the late sixties, both the Klipschorn and the Belle Klipsch, or La Scala, had 16 ohm impedance, to reduce the influence of long wires. At the time Klipsch also produced two more models: Cornwall, which was a 50W bass reflex, and Heresy, the name was self explicatory, a small 25W infinite baffle. Here is a picture of the La Scala
