Jensen monitor 5

CHI-TOWN
Buenos dias, I picked up a pr of Jensen monitor 5 last night from the local goodwill, all the drivers work and the grills and cabinets are in good shape.
The only thing is that both woofers need re foaming and this will be my first attempt to re foam a speaker, any tips will be gratefully appreciated also are these speakers good enough to take to a pro for re foaming or it's no big deal if I accidentally trash the woofers while trying to re foam them? Got the pr for diez pesos:D
Thanks.image.jpg

Vintage jensens were very highly regarded speakers. The later Jesnens with "capital Js, were still very good speakers. Get the refoamed. They're worth the effort.
 
re refoam

You may not have to refoam them at all if you don't want to. I notice that the surrounds have cracked radially instead of around the circumference the way most others do. I have a set of speakers which did the same thing and I was able to recover them using clear, flowable silicon sealant - the kind you use to seal around the windshield of your car. Take the speaker out of the cabinet. Then apply the sealant with a small paint brush, spreading it around and over the cracks in the surround and covering the whole width of the foam. When it starts to seep down through the cracks just pick the speaker up and hold it upside down so that the sealant starts to run back the other way. When you do, it will start to gather on the crest of the surround so all you have to do is turn it over again. Keep turning it over and over until it stops flowing in a nice even layer, which takes only a few minutes. With a speaker that size you may have to do it maybe a quarter or a third of the circumference at a time or it will start to dry out too much to control the flow before you get all the way around. So don't freak out when you put some fresh silicon on some that has already dried a bit just because it goes white then. It will clear up when it dries, too. And it has to be the flowable silicon. This method allows you to keep the factory centering of the cone. It also restores some compliance to the speaker as well. And if you want to be really thorough you can do both sides. If it doesn't work out or you just don't like the looks of it the silicon simply comes off with the foam. See pics for the one I did.

I'm not sure I'd try that repair on the much larger surround on your woofers. It's a good repair if you have cracked surrounds on a smaller mid-range or tweeter, but I think you might change the dynamics of your woofers as you will be adding a lot of weight to them.
 
Replacing surrounds is not difficult, it requires some patience, do a search here or on the net, there is plenty of info on how to do it.
