Please see pictures and video for cosmetic and functional condition. Will ship carefully packaged by me, thank you. If one component can be said to embody the innovation, quality and attention to detail that defined JBL, it has to be the D130. This wide range 15 driver was introduced in 1948 and remains in production to this day as the updated E130. This driver was responsible for establishing the nascent James B Lansing Sound as a force to be reckoned with in the loudspeaker industry. The D130 was the second low frequency loudspeaker introduced by James B. Lansing Sound after the D101 of 1946. It was personally designed and developed by James Lansing. It incorporated a 4 flat wire voice coil attached to a light, curvilinear cone with a 4 aluminum diaphragm instead of a standard dust cap to extend high frequency response. The coil was immersed in one of the strongest permanent magnetic fields yet developed for a loudspeaker. It resulted in a driver with outstanding sensitivity, range and dynamic response. The 4 flat wire coil was the single most innovative feature of this design. It was the first low frequency driver to incorporate a coil of this large diameter. To achieve the maximum motor strength, the coil gap was designed to be a very narrow 0.05. The degree of precision necessary to maintain such a large, exact circular shape for both the coil and the gap was unheard of at the time. It was years before competitors were able to match this feat. The advantages of this innovation are many. The large coil dissipates heat more efficiently, increasing power handling and reducing dynamic compression. The large coil also places more wire in the gap for fewer turns. This allowed the coil to use a single layer of wire that could fit in a narrower gap. The result is maximum utilization of the energy from the magnetic structure and maximum efficiency. Finally, the large diameter coil yields a stronger moving structure since the force applied to the coil is transferred to the cone over a larger area. The cone is therefore less prone to breakup. There virtually is no loudspeaker market for which the D130 did not find application. In the 1950s through the 1960s, it was the loudspeaker that defined the home hi-fi phenomenon. It was used in more component hi-fi systems of that era than any other speaker. It was the workhorse driver used in James B. Lansing Sounds first commercial systems for the movie industry. It became a mainstay in the musicians market after Leo Fender incorporated a version of it in his early amplifiers. In the rock era of the seventies, it was common to see walls of D130s providing sound reinforcement at concerts.

Sie bieten auf ein Paar JBL Control One AW - wetterfeste outdoor Wand Lautsprecher. Sie weisen sehr geringe Nutzungsspuren auf, wurden nur einmal aufgehängt, in einem Innenraum. Dementsprechend noch nicht mit Wetter in Berührung gekommen. Es gilt, wie immer bei Privatverkauf, keine Gewähr, und keine Rücknahme. Wir schließen jede Sachmängelhaftung aus.

Da der Artikel von feres2002 nicht bezahlt wurde, wieder im Angebot: JBL Control ONE AW Lautsprecherpaar mit neuen Professional Logos. Das Paar wurde noch nie im Außenbereich eingesetzt... Die technischen Daten können Sie im letzten Bild einsehen. Weitere JBL Artikel finden Sie in meinen anderen Angeboten (solange noch nicht verkauft). Kurze Info zur angegebenen EAN-Nummer: Leider muss man die aus dem ebay Produktkatalog angeben, diese ist aber falsch und dementsprechend ist man gezwungen irgendeine x-beliebige anzugeben.
