ESS speakers "Translinear" Transstatic

These were speakers designed by California based company called ESS, that is, Electro Static Sound before they used the Heil Air Montion transformer. These models were current in 1970-1975. I am curious if any one still owns either of the above models, or has seem them listed on any of them listed in the used audio web sites. They were incredible speakers for their time,and sounded as good as many of so-called elctrostatics of today. They used good driver elements, for example, the KEF B-139 oval driver for the bass response.If anyone has knowledge of either of these above vintage speakers,please leave info on this Web page. Thank you!!

Wow, i bet that post brought up memories, huh Albert ??? : )

Thanks for filling us in on that. I have a good sized batch of the RTR e-stat tweeters that i'll be working with quite soon. Your comments about the Soundlabs' bass. From what i know of these, they are an all E-stat design, correct ? Maybe i'm misinformed and they are a hybrid. If they are completely electrostatic, I will HAVE to hear these things if they've got bottom end "oomph" that can compete with dynamic drivers. Sean

Sean, you are right about the memories, it was pleasant thinking about the ESS again. Your question about Soundlab, all the large speakers in the line have excellent bass, and are exclusively electrostatic. The mylar driver has very low excursion, but is ultra fast and phase accurate. For what it lacks in deflection, it makes up by radiating area (in excess of 15 square feet). Properly set up, you are assured to get the "oomph" you describe. Electrostatic bass still "sounds" different from a traditional piston woofer, a music session with your favorite software should determine if it has the sound you like.

Very entertaining comments Albert. Were you still at ESS when they went to the Heil AMT technology? I know a lot of people love to knock those speakers. My father has a pair(in my home no less), and it has always intrigued me to take them apart, modify them, and see what happens. While I have never really given them a lot of time in the past years, I remember some good qualities of the driver. Thanks for your information!

ESS is still in business. You can view their web site at http://www.essspeakers.com. Their product line has not changed very much of the years. I used to own a pair of AMT-1As with the Heil. I thought the Heil was a great driver. Unfortunatly, it was not well integrated with the 12 inch woofer used in the speaker (hard to do). The Heil AMT is being used in speakers other than ESS. There are 2 Swiss speakers the Oscar Aulos and Kithara (the former was recently well reviewed in Soundstage e-mag. There is also a British company called Orchid that is using the Heil.

Hi, I owned a pair of ESS AMT 1A's in 1975 through about 1980. I gave them to my sister and she still has them and loves them. The woofer surrounds disintegrated about 12 years ago, but the dealer (a local TV store) ordered new ones for me and as far as I know, they are still functioning well. My sister likes them, anyway. They are the highest-end speakers she has ever had.
I remember the day I had these speakers delivered, I thought I had way overdone it in size and cost. However, 30 years later, I see I had many more extreme excesses to go, audio-wise.
