    You can get generic screen type dust caps, but they may not match exacly, so you'd be better off doing all of them.
    You would have to carefully cut the old ones out and glue the new ones in place. It's not for the faint of heart, especially if you've never done it before.

    Like westmassguy said; not for the faint of heart, and replace all 16 to make them match, or at least all 8 in the same cabinet. TAKE YOUR TIME and be careful, it is easy to cut the lead wires if not careful. Also be sure to get a cap that breathes well; these drivers are vented through the caps and spiders.

    I measured the existing dust cap with my one bloodshot eye this morning, and looks like 1 5/8" accross. You would need a new cap slightly larger than 1.625". My supplier has has mesh caps, lip down, 1.64" which should be perfect. If you can't find them from a retail supplier, I can find out cost and availabilty for you.

    If they're dented instead of missing completely, pop the dent out with a small pick. Reach in through the mesh, pull the fabric into place with the tip of the pick.

    Some folks have used a vacuum-cleaner to "suck" the dent out, but that wouldn't be my first choice.

    Don't use vacuum cleaner.
    I've tried those and it's waste of time. 1st you don't get proper suction, 2nd, dust cap is stiff, vacuum just can't do anything.

    What works 100% is below. I fixed monitor 7's smashed in dust caps as well as JBL L100T's and it's now perfect on 7's and very good on L100T's due to worse condition and much bigger dust cap on the JBL.

    Cut q-tips in half.
    Put a tiny dab of speaker glue/aleene's tacky glue on the cut tip and put on the middle of dust cap.
    Hold it or put something so it's vertical while the glue sets.
    After few hours, when glue is set, wet the dust cap with some water.
    Don't douse it but put a drop on a finger tip and spread so it's moist.
    Then pull the q-tip slowly and it'll come out perfect.
    Then while pulling, use a hair dryer in hot settings until the q-tip releases.
    It should bring all the glue on the q-tip but if not just slowly scrap the remaining with q-tip or something similar without pushing the cap.

    Vacuums work very well if you have one that has a suction bleed off (or whatever it may be called). Some vacuums have a moveable cover over a hole in the suction tube. Opening this hole lowers the strength of the vacuum at the end of the tube so full strength is not applied to the dust cap. I prefer this method as it leaves no holes in the dust caps but have used the pick/pin method before and it works well too, just not as good for me. The vacuum places even pressure to the whole surface and for me helps to get a smoother surface back to the dustcap. With either method use caution.

    Could work, could also cause irreparable damage if not done correctly

    Well you need a new vacuum then.. My house vac hose is the same size as the dust cap, the dust cap is mesh so air moves freely. The only danger is if you try to pull vacuum off driver while turned on it will pull driver voice coil off the former hence have a helper..

    For me it has worked the best on Polk drivers because of the mesh type cap. Yes it could cause irreparable damage and that is why i always say have friend work on/off switch and hold driver to keep from moving in or out as best as you can without undo force and quickly turn on/off.

    This has worked great for me on multiple occasions. It could indeed cause damage if not done properly as Pitdog describes. I personally have never had a problem.

    I have done this with multiple vacuums and it has worked great for me each time, even when the nozzle was smaller than the dust cap I simply move it around a bit on larger dust caps. As Pitdog describes you MUST hold the driver and DO NOT pull on the vacuum while it is applied to the speaker. The suction could easily pull the voice coil over the former. You must hold both the driver and the vacuum still when doing this.

    Yeah, yeah, yeah.

    The point I was making is that it's silly to buy a new dustcap when the original can be returned to proper shape with just a little bit of luvvin'.

    The selection of luvv tool is up to the speaker owner.

    I thought spiders breathed through their eyes, or is that frogs.

    Yep, gonna practice on some old speakers first, maybe catch a tube video again. also need ideas on how to remove some rust from the driver screws. BTW, these are my $50.00 SDA's I got a few months back, they were in a building fire, front grills are shot, tons of smoke/steam residue that has cleaned up fairly well, speakers actually still sound good, connect cable didn't survive the fire or was lost??? 3rd tweeter from the top downward is out on both speakers, might just replace them all??? Concerns now are the grill covers and the dust covers then the tweeters and then the cable.

    Other old stuff not being used.
