ESS donned the slogan “Sound as Clear as Light” and their AMT speakers produce just that. 

If have never heard an ESS AMT speaker, you are missing out big time. ESS uses an ultra unique design for their tweeters. The tweeters are called an Air Motion Transformer diaphragm. ESS designed the AMT 3 tower with 2 10 inch subwoofers and a 6 inch midrange. The amazing precision of the AMT paired with the extreme lows achieved by the dual subwoofers create a perfect sound that seems impossible.

More on the AMT tweeter...

The Heil Air Motion Transformer (AMT) diaphragm is low mass and high output allowing for a uniquely high combination of efficiency and bandwidth.  Enabling it to efficiently reproduce frequencies over a wide range, between 40 and 24K Hz.  The AMT is a dipolar transducer, which gives it sound of a live musical instrument equally generating as much sound from the front as to the rear.  This creates a more natural musical ambience.  The diaphragm’s shape delivers wide dispersion horizontally while tightly controlling the vertical sound which creates a wide soundstage and minimizes unwanted floor and ceiling reflections.

The Heil diaphragm is made of soft, quiet mylar to reduce background noise and is bonded with conductive aluminum strips. The low mass diaphragm is suspended in a massive magnet structure concentrating an intense magnetic field around the diaphragm.

The ESS Heil Air Motion Transformer (AMT) is the most significant loudspeaker breakthrough of the last half-century and is licensed exclusively to ESS. Once you’ve heard it, you’ll agree that the ESS Heil AMT indeed delivers “SOUND AS CLEAR AS LIGHT.”

What people say about the ESS AMT 3

Quoting one ESS AMT 3 speaker owner, “the sweetest, luscious, detailed, massive splash of high frequency you may come across at 97db efficiency”

The AMTs carry the midrange and treble frequencies. Fused with recently replaced six-inch drivers that reproduce the lower midrange and upper bass, as well as four fresh ten-inch woofers.  The crossover is original and the caps recently tested.  SpenCertified!

I have always been impressed with the items I received even after a couple years they continue to work. This is the reason why I always keep returning as a customer.

Very happy with what we got! I made the mistake of first getting this item from Amazon and received it not working at all... I will order from them again and highly recommend them to everyone!

For a couple of years, I have been looking for a replacement for my Toshiba DVD Recorder that was starting to break down. I had placed four orders with Amazon....3 of the recorders did not work and had to be returned, the fourth order was canceled by the seller before shipping with no explanation. An internet search brought me to spencertified.com and I found a refurbished Toshiba recorder similar to the one I was using. Without high expectations, I placed another order with them. SpenCertified let me know when my order was placed and kept me fully updated during the shipping process. The recorder arrived in about 4 days (much quicker than I anticipated) and works perfectly. The box included the recorder, remote and users' manual and advertised. I am very satisfied with my experience with SpenCertified and plan to order additional equipment from them. I highly recommend them.

Being a senior who refuses to give up VCR'S, I was in a panic because my last one died and no one sells them anymore in CA. Luckily I discovered SpenCertified, and will never have to worry again. I can't begin to tell you how pleased I am with the fantastic service they provide. My sets arrived in a timely manner, extremely well wrapped and the friendly emails offering any help were appreciated. I will continue to do business with them in the future and plan to refer them to all my friends. Thank you, guys... YOU CAN BUY WITH CONFIDENCE.

When my beloved VCR died, I discovered new ones were not being manufactured as before. All my tapes, collected over many years - - lost!? All future recordings - - lost!? What to do? Then, I discovered SpenCertified. I was wary. Was this a scam? I was afraid. Would my purchase truly be guaranteed? I wanted, I NEEDED, a working VCR, so I made my order. The packaging was perfect, the VCR was even better than advertised, Spencer was extremely helpful. I am a very satisfied customer.
