I inherited some speakers from my Dad who passed this past year. I'm not sure what to do with them. The woofers are shot, the foam is damaged on all 4 woofers. I have some older ProAc EBT's which I love and I am sure these Super Towers would be great if they are worth repairing. I am just looking for some suggestions.

There are refoaming kits you can buy from places like PartsExpress and do the work yourself. My condolences on the passing of your father.

I watched the video on how to refoam a speaker. Have you done a refoam DIY? I am curious if the speakers sound the same.

I pulled a speaker and the brand is Scan-Speak. Type: 18W 4214 Paper, Code: 8542, PW: 357.

I believe this is the speaker specs:

I am not sure exactly how you measure the size for ordering replacement foam. I took a few photos with a ruler.

You measure from one side to the other....You have two 7 inch woofers and a 1 inch tweeter. That speaker may be the closest one you can get...seeing lots of speaker companies like ProAc have their speakers voiced a little different from the stock speaker sold by the same manufacturer like Seas or Scanspeak. You should take a look at the tweeter as well to see if it says Scan Speak or Seas. Dont know if that is the original tweeter. All the pictures I have seen on that speaker are round.

I was able to get the original surround foams. The foam material is so thin. They enclosed some Seal Cement (generic stuff from McNett) that I am not sure is ok to use. I have not glued anything in place yet, just test fitted and it looks great. Just not sure if I should use that glue.

This was the best $55 bucks I have spent in a long time. I just finished installing the speakers and did some listening and the ProAc's are back in business.

If I had to do it again I would not use that contact cement, it's a do or die situation, you have no chance to move the foam around once it touches the surface. I think the white glue is a better way to go.

I want to thank Brian and Barney at Madisound for having the original surround foams. They were very helpful on the phone and email.

Depending on the chemical composition of the foam, it can last for decades or for a far shorter period of time. In any event for the price of less than a weeks worth of Starbucks, you've managed to restore a decent set of speakers and in a small way do honor to the memory of your father. Good for you!

Hi Gary,
you did a wonderful job on re-foaming the speakers.

I also need to perform the same repair in some proac speakers.
I was searching in the Madiesound website but can't find the foam surrounds, is it in any of the section?

Thanks

You have to call them, it's not on their web site. They are very friendly on the phone.

Hi

Exactly the same thing has happened to my Super Towers. I'm just about to contact Madisound. What is the white glue you advise to use?

Are your speakers still going strong?

Thanks

I used the contact cement that Madisound recommended.

I finally moved the speakers to my home in SC. One issue some how I lost the tip toes. I have them on carpet and they are not too stable. Does anyone know the thread size or where I could find an after market that fits?

Parts express has a lot of spikes available, I'm sure you could find a set that will fit.

Dumb enough to spend lots of cash on this junk!

I too have an early pair of Original Proac Super Towers...and was wondering if you ever solved the issue with the strident tweeters. Any substitutes other than a square metal square plate bolted to front of ST with round cutout for a Seas D2010 soft dome.

The whole output of the ST seems tilted towards the high end....compared with 3.8's, 1Sc's and even the Tablette 50's.

Did you ever find replacements for your tweeters. Mine are also dead. The only part # on the speaker is 95-6501.

I contacted Madisound where I found the surround foams for the woofers and they confirmed the tweeters (MB Quarts) are no longer made. They recommended Morel MDT30S 1" textile doom tweeters. I decided to try them. They arrived today and were an easy fit in the Proac's. Nothing is going to match that square hole so Brian recommended I just use some felt with a sticky backing. You need to cut out the felt to fit in the corners. I also had some black sheet metal screws to hold the speakers in place. The screws that were on the MB Quarts could not be used.
