ess heil amt pair never used new in box. Certificates as shown in pictures. Sequential serial numbers. I ordered these years ago for a project that never happened. I never even took them out of their boxes. I will ship in the same box that ESS used. Shipping weight is 32lbs! These things are heavy.

A pair of AMT tweeters that I removed from some ESS tempest lab series 2 speakers. They have some rust on the front, and one of them was loose in the frame, so I took the old glue off and repotted it with electronics grade RTV 162. They both measure well and sound good with music using my 1000hz test crossover. Please look at the pictures and ask any questions before bidding. This is a great pair to play with at a low price.

For purchase, a gorgeous pair of ESS Heil amt 4 ohm woofers. The surrounds were just replaced with open cell polyether foam in June 2023, and the bextrene cones are very clean. As most early ESS builds, these woofers have 2 voice coils wound on anodized aluminum formers. Resistance measurements are 3.4 and 3.3 ohms, respectively. They should be considered an essential replacement if your woofers are indeed compromised. Utilized in several models of amt1(x), these are drop-in ready for models such as amt1a, 1b, 1c, amt1am, amt monitor, and all bookshelf variants of those models. These are factory original bextrene 12 drivers by ESS of Sacramento, removed from amt1b loudspeakers. These drivers are optimized for the specific dividing networks and cabinet offerings that were available during the production years of amt1b and monitor tower builds, circa 1977 through 1980. Modern replacements (from ESS currently) 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 off the shelf woofer drivers provided by the new Los Angeles based ESS. Packing will be very stout, expect these to arrive as advertised. UPS or FedEx will be the carrier, please let me know if you have a shipper preference. 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 usually ship within 48 hrs of completed payment. Thank you for looking.
