!!! KEIN VERSAND, NUR AN SELBSTABHOLER !!! Es handelt sich um ein Paar der Vintage-Lautsprecher ESS Heil AMT 1b aus den 1970er-Jahren. Sie haben einen besonders warmen Klang und dank des Air Motion Transformers (AMT) eine brillante Höhenwiedergabe. Weitere Informationen vom Hersteller:https://www.hifi-wiki.de/index.php/ESS_Heil_AMT_1b Das Original-Handbuch liegt bei, s. Fotos. Die Hi-Fi-Boxen wurden Ende der 70er gekauft und befanden sich seitdem in einem Nichtraucher-Haushalt. Sie haben normale Gebrauchsspuren. Hinweis: Ich wurde gerade darauf aufmerksam gemacht, dass die verbauten Bass-Lautsprecher nicht die Originalteile sind, mit denen die Boxen damals hergestellt wurden. Ich habe sie geerbt und kann den ursprünglichen Besitzer daher nicht mehr fragen, wann und wieso diese ausgetauscht wurden. Da er ein Hi-Fi-Liebhaber war, gehe ich jedoch davon aus, dass er damals gleichwertige Teile verwendet hat. Mir sind keine Mängel an dem Produkt bekannt. Als Privatverkäufer schließe ich jedoch jegliche Gewährleistung, sowie Umtausch aus. Es stehen übrigens auch weitere Vintage-Hi-Fi-Komponenten zum Verkauf - s. meine anderen Auktionen. !!! KEIN VERSAND, NUR AN SELBSTABHOLER !!!

ESS amt1a, 1b, 1c, 1d, type grill covers. Fitment of these tops are for the truncated ESS floorstanding loudspeakers. These are both in uncommonly great condition. The frames are strong and intact. The grill material is undamaged and clean throughout. You will be pleased with this set, should you decide to update your existing old grill tops. Ive marked the shipping cost at 118.00 and will refund the buyer any overages, should that come into play. They will be carefully packed in 1 extra large sturdy carton. I usually ship within 36-48 hrs of a completed purchase, but may need extra time to pack them well. Thank you for looking.

A pair of original 12 inch poly drivers with cast baskets from ESS labs of Sacramento. They are the original drivers for the amt 1b but can be used with other ess speakers using 12 inch drivers. Both drivers have new foam and have an hour of testing on them. Both cones have tears in the cones that have been patched.

For purchase, a gorgeous set of ESS Heil 4ohm woofers and factory passives. The surrounds were just replaced with open cell polyether foam, and the cones are very clean. The radiators are original to early and later ESS 12 builds. Resistance measurements of the woofers are 3.2 and 3.3 respectively. The rich sonics incorporated in the original bextrene cones should be considered essential to the overall sound of your ESS speakers. Utilized in several models of amt1(x), these are drop-in ready for models such as amt1a, 1b, 1c, 1d, and amt Monitor, including all bookshelf variants of those models. These are factory original 12 drivers by ESS of Sacramento. These drivers were optimized for the specific dividing networks and cabinet offerings that were available during the production years of amt1b, and amt monitor tower builds. Modern replacements (from ESS) are not engineered to be coupled with amt drivers, nor your existing crossover networks where applicable. No testing or sampling has been performed with the new, generic paper woofer drivers provided by ESS, currently. Packing will be very stout, expect these to arrive as advertised. FedEx will be the carrier of choice. As with all of my listings of ESS equipment, if you are looking for parts from that era of long gone builds, feel free to inquire as i will assist with whatever parts i may have inventory of. I will ship within 48 hrs of completed payment. Thank you for looking.
