I recommend a screwdriver. Or Allen key. Hard to get a clear enough look to tell.
Either way you take em apart. Then while waiting on the replacement (the part# is probably printed on the driver, if not VA can provide) you order some fo.Q tape and TC. Remove speaker gaskets (if any) and apply thin fo.Q tape around the perimeter of the speaker frame. Apply strips of fo.Q tape to the speaker baskets. All of them. If internal wire clips to the speakers then cut this off and solder. All of them. Save a little fo.Q tape for your tone arm. Use almost all of the 2 sheets on the speakers.
Apply TC to all internal speaker wires. Apply to caps and choke on the crossover, if you can get at it. Cover the outsides but do be careful to not create a short anywhere. Put a coat on top of all the fo.Q tape. Put a coat around the speaker magnet. Put the speakers back together.
You will now be so happy to have upgraded your speakers to such a level as you never dreamed was even remotely possible.
You shake your head, pat yourself on the back, and pour yourself a cool tall one. You earned it.
That’s my recommendation.
