I tried a 3.5" speaker just like the Rockfor suggested above, it is way too small and the housing has a large airgap between it and the speaker. It acoustically wont work. The correct size is 4".

I just repaired one that had a 1"-2" tear in the foam surround.

I just brushed some speaker repair stuff (in the link below) and let it dry over night and it is fixed.

I have another Play1 with another bad woofer and the failure is different. On that one, when i push the cone down i can hear what sounds like metal on metal. It also has a tear in the foam surround but when it was glued back the metal sound is still there. Pretty sure that woofer must be replaced or re-coned? Anyone had one of these successfully re-coned?
