Installing Vintage Speakers

EvilQ · 29th September 2011, 11:04 PM

I am working on some Altec Model 5's and I am not sure how to bed the repaired woofers on the sound board. They were pulled by the first owner and he used silicone when he put them back. Is that ok or should I just use putty?

I wouldn't use silicon because it makes them to hard to remove if you ever need to. There are a variety of foam tapes (neoprene foams are a little more substantial and longer lasting) and you can always use modeling clay. Roll it out on a smooth surface until its about a 1/4' wide and place it neatly around the middle of the mounting surface. Be careful that you don't get air leaks around the screw holes.

You can use preformed gaskets or making it yourself cutting it from a sheet of vinyl or using auto/engine joint gaskets from your garage.

Hey, thanks David and Inductor, the gasket idea sounds like the way to go. You are also right about getting the speaker out of that silicone. I thought the speaker frame was going to bend on me. I also just got a pair of Audex (not audax) made in Winnipeg 12" 3ways to refoam. These sounded good when I put a little voltage to them but there is no info on this company. Ever hear of them?
