Refoaming speaker surrounds

I have an Entec sw-1 subwoofer in which the foam surrounds on the three drivers has deteriorated. Does anyone know of a source to have these speakers refoamed, how much it might cost, or if it is a possible DIY?
SPEAKER WORKS NORTHWEST sells "Diy" foam kits. Instructions included, rather simple too. Web page Hope this helps, Tom
Try Millersound 215-412-7700 About $30.00 per dirver, & the quality of his work is excellent. Good Listening
Try Just redid (DIY) a pair of NS-500's. Holy shit, I never thought my Dad's speakers could sound soooo good. Get the Deluxe kit. (alignment tools work GREAT) Kurt
