Can a woofer function with a hole in it

I bought a speaker and one of the woofers has a hole pierced but the seller assures me it still functions . The woofer is only a 5 inch and I am going to be using this speaker for surround duty so can I get by with it in the mentioned condition ?

Bear in mind that the speaker operates mids with the electrostat panel and the woofers just support the bass

    But not the same as if it was intact. Is the hole in the surround or the cone?

    Patch it,just don't use anything that's too heavy and will mess up the balance.

    You should be able to contact the manufacturer for a replacement because a woofer with a hole in it does not work correctly.

    sure it will work, but it will alter the tuning of the speaker system (driver plus enclosure) - depending on the alignment, the impact of that alteration can be more or less severe.

    A puncture wound in a woofer cone can be fixed with a dab of GC "Service Cement" (still available from electronics parts suppliers, if you can find one in your area). Larger damage can be fixed with a single ply of toilet paper and a good, thin, "wetting" solvent-based glue.

    Both of these age-old repair techniques are meant for paper cones and may not work as well (or even at all) on more esoteric cone materials.

    Just poke a hole on the other side and repeat on the other woofer...

    LOL

    ya, that'll balance it for sure :)

    but sure to drill the hole in the exact spot and size on the other speaker to match the broken one! Match in looks and sound!

    P.S. I loved the outside of the box comment.

    Kind of a bad spot for patching it and I have a feeling a lot of common glues will melt that cone. Contact ML. I'd bet that a replacement isn't more than $50-$60.

    I would replace it. Patching that might be pretty tough. I have seen people use silicone based sealants like blue RTV but on that type of cone I don't know if it would work. It may melt it.

    By the way, What did they do to that poor center. Looks like they threw it around the house with sharp blades in there hands.

    Joe if you think that pic looks bad wait till I load up some new pics today :eek: . I bought this for $320 and the actual cabs smashed to bits but its a $1600 center and the panel is only 5 month old so its going to be my first DIY speaker project and I am excited to bring it back to life
