    i got a Hartke A70 for a few days, but something coming up. there's a 'brrrrrrrr' sound when i play some low note, then i check the speaker on the surface (front cone) and find no cut or broken at all. then i check behind speaker from a hole to make sure that there is no spider web, dust or something else and i found it is pretty clean

    i'm afraid that something going on inside the speaker cone, any suggestion for this?

    for the worst possiblity, if i replace the speaker (for a better one maybe) is it worthed? the speaker spec is 12" with 8ohm, so what kind of speaker will fit for this amp?

    What's your bass knob set at? How loud? Could be you're just asking more from it than it can give you...?

    +1 pushing the low eq eats your power, and is hard on spkrs. CUT the lows.
