I rebuilt my ESS Towers and they sound just like I bought them back in 78. Highly recommend them.

ESS AMT 10" speaker
speaker came very quickly after I ordered it. Very good quality, heavy duty leads. Piece of cake to install it and the sound is excellent.

these speakers were installed in a pair of ess heil towers that I purchased in the mid-1970s. they arrived nicely packed and damage free. I did have to make some minor alterations to the tower speaker openings as these are slightly larger than the original, perhaps due to the cast aluminum frame. Performance is great, solid bass and power handling capabilities.

ESS AMT-1 Tower owner
Just like the others said. Replaced the woofer pair with these. Great product. Great service. Fast shipping. Great support after the sale. Modifications of the cabinet less effort than first thought. Thanks to reviewer Doug Pendgraft,encouraged me to tackle it. We're rockin' and rollin' again BABY !

My 10' woofers were shipped promptly and in perfect condition. I have installed one of them and it is working great. My only glitch was that it didn't quite fit into the speaker opening that the old one came out of. I had to grind out the fiber board and enlarge the opening in order to insert the woofer. It wasn't a big deal, but took some time. I'm very pleased.

Owner of ESS PS-5s
I recently ordered a pair of these woofers to replace the original 10" woofers in my PS-5 cabinets. One of the original woofers needed to be replaced. The speakers were shipped on the same day that the order was placed so I received them within a few days. I did have to modify the cabinets to be able to mount them with the new speaker footprint since my original woofers were round. This matched comments from others and also from Sean at Simply Speakers . This was not too bad of a task to get done. The replacement woofers appear to be comparable to the original woofers. These replacement woofers have given new life to my PS-5s.

I purchased 4 of the ESS AMT 10B speakers back in the 70's and they are still amazing. One of the downsides of the foam surrounds on the woofers is that they need to be refoamed every 10 years or so. When I saw the IMPROVED foam surrounds on the brand-new ESS 10" woofers.....I had to pull the trigger. Now my ESS AMT 10B all sound better than new. Thanks much Simply Speakers!

I recently found out about OEM replacement woofers for my AMT-1 tower speakers. I purchased these in the early 70's while stationed in germany after listing to many competitive speakers of various price ranges.These speakers have never failed to enhance the listening experience and I was sad to see the supports for the woofers had rotted away a second time. Finding that I could restore these AMT-1 to their former glory with an exact replacement was exciting. The folks at Simply Speakers very helpful and ask questions to make sure I would not have a problem. The speakers from ESS are impressive and substantial and have restored my speakers to like new. I couldn't be more pleased with the product or service. I am going to rebuild the ones I took out with better surrounds and use them in another project.
