Up for sale, a very nice SINGLE ESS Heil 12” woofer. These woofers were just professionally refoamed! It came out of ESS Heil AMT 1a bookshelf speaker, but will wit many other ESS models using the 4 ohm 12” woofer. It was fully tested after the foam job and passed with flying colors! The foams are from Simply Speakers, not junk! Simply Speakers recommended trimming and splicing the foams to fit perfectly, which is why there is a small piece overlapping rhe splice (see photos). Please see rhe attached pictures for condition and ohm reading. View my other auctions for an array of interesting items at great prices. Please ask for additional pictures or videos if needed.

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.

For purchase, a gorgeous set of ESS Heil 4ohm pulp woofers and original passives. The surrounds were just replaced with open cell polyether foam, and the pulp cones are very clean. The radiators are of closed cell design, original to early ESS 12 builds with full 3/4 backings and mass weights. Unique to ONLY early ESS builds, the woofers have 2.5 voice coils wound on anodized formers, unlike every other cast framed offerings from ESS which have 2 voice coils. Also unique to this pair, the backside of the cone base employs a dampener to reduce unwanted harmonic overtones in the upper bass region. Resistance measurements are 3.47 and 3.54 respectively. The rich sonics incorporated in the original lightweight but dense pulp cones, should be considered an essential upgrade to the overall sound of your ESS speakers.
