    im looking to buy my uncles hartke 410xl, but theres an annoying buzz/rattle in the bottom left speaker. its not distortion, and i know its the speaker not the cab or anything...it doesnt sound blown, just has a buzz like somethings vibrating in it...? can someone tell me what i can do about this?

    Could be anything from a rattling grill to a rattling wire connecting the cones to whatever the heck they connect to, to a blown speaker. Best thing to do is pull it and see if it's something obviously mechanical. Hartkes aren't known for blowing easily, so it may just be something mechanical.

    Could just be the nut(s) holding that speaker to the cab have worked loose. Like Rob says, open it up to see.

    It is very common for the dust caps to come loose on those drivers.

    Most of us had to epoxy the cap back on.

    If that doesn't fix it, you may need a new driver

    My bet is that its the dust cap that's causing the buzzing. Every Hartke aluminum driver I've owned had that happen.

    Its a cheap and easy fix to reglue it back on properly, but it makes the EXACT sound you are describing.

    It is the black dome shape in the centre of each speaker.
    It is made of thick paper and is glued to the aluminum cone.
    It has likely come unstuck around its' edges and needs regluing.
    I was told to use epoxy

    Be very very careful with the aluminum, as it gets damaged very easily and those ribs in it get flattened easily

    I don't think so, as the paper absorbs it.
    Go buy some epoxy...and follow the directions carefully

    If it is the dust cap, you should be able to see where it has seperated from the cone.

    Check for cracks in the cone and check where the foam or rubber surround is attached to the speaker frame and to the cone.

    I've also read that some speakers have problems with the magnet assembly rattling against the speaker frame if they weren't pressed together correctly at the factory- the fix mentioned for it was to jam part of a razor blade between the magnet and the frame and put some silicon on it to hold it in place.
