Post Subject: Nil riskPosted by scooter on: 9/17/2010

"quote" I do not share the Scooter’s and jessie’s fear about the toxicity of petro-based products. Yes, petro-based products are not good near driver but I do not think that I spayed driver with gasoline. I did a test and confirm that foam doe not penetrate the fabric I used. Foam does not make it soggy or wet. I used fabric from think tarp. Foam does not have fume or gas and when it cures it absolutely inert to any organic things. It is not to mention that the cone was under the foam (in case of fume) and separated with very thick fabric. So, I do not think that any damage or impact was done to driver. I think that sitting form years in weather non-stabilized storages might make more damage to it. Of course you never know, but I do not think that 10 min proximity to uncured polyurethane foam did anything to the driver diaphragm.

Romy's intuition is reasonable in my experience. I believe that the real risk was foam breaking down over time from coming in proximity with silicone or other petro-based products. The likelihood of speakers having a negative reaction to just foam which largely rapidly cures is nil in my view.
