    O ring gaskets missing

    Hi,

    today I received a pair of used and reconed 2225H's to build two subwoofers. Unfortunately the O ring gaskets are missing, and without them I can't front mount them. How can I replace these gaskets?

    Best regards!

    O Rings

    Hello;

    The O Rings are hollow tubes that are melted or bonded end to end to form a ring. This material is available for gasket making as is solid round.

    Solid round O rings are not sufficiently compliant for mounting speakers in wood.

    I will cross section measure one for you if it will help you find some suitable material.

    Barry.

    Yes, but I think it's rather difficult to make .

    Best regards!

    The tube I have from JBL kits measures:
    2.75mm outer diameter.
    1.25mm inside diameter.

    It is easily melted or bonded together with instant adhesive. Melted is stronger and remains flexible. Use a hot surface rather than flame.

    Thanks, I'll have a look ! The circumference can be calculated by the cutout diameter from the datasheets multiplied by Pi, I think?

    Best regards!

    Gasket 34499 remains a service part from JBL. If you have a local JBL parts importer, they should be able to source it for you. They are not that pricey.

    Thanks also to you! I just contacted the German importer, hoping to get an answer soon.

    Best regards!

    No you can purchase them JBL makes paper gaskets for 8-18" drivers that you used to be able to purchase. Any re-coning shop should also have them.

    Ok, so the gasket 34499 appears to be unavailable here in Germany. I'll go and ask for paper gaskets. Or I'll search for foam coards that I could glue to form O rings.

    Best regards!

    Thin weatherseal foam tape works just fine too.

    As it has to be applied in a conical shape, will it stick sufficiently? But soon I'll try by myself . Today I've fetched the enclosure panels, and after our vacancies, i.e. in about four weeks, I'll build the subwoofers.

    Best regards!

    Sorry, conical? It should be a flat ring shape?
