My brother was trying to help my collecting and bought a pair of CS-D9900 Floor standing speaker for me. These are big and heavy, and he swears they were in good shape when he bought them. The owner claimed they were sealed in the original box since 1990. When I came to get them there is a big hole in one of the woofer FOAM surrounds. I did expect them to be foam and was going to coat them with rubber cement if the were intact. What do you think I should do now. ReFoam? I cannot find much information about this speaker except Rick stereomanuals says these were produced in 1986 and replaced the CS-C9900. The CS-C9900 were 3-ways with 16 inch woofer, 6 inch mid and 2.5 tweeter and retailed for $200. I do know that the D9900 is a 4 way, with an added super tweeter with metal angled diffusion grille. The numbers on the 16 woofer are 142976 .....PT-81 8619 ....doesn't have a very large magnet...Are 16 inch woofers and foam kits available anymore? I am sure these are not collectable or anything, but I would like to get them going to make my brother feel better. I guess I could coat the intact woofer with rubber cement and then try it out. Your help would be appreciated.
