Welcome to the CSP!

To answer your question: Maybe.

You should test the woofer seal by pushing the woofer in. Use 3 fingers like a tripod around the dust cap and push. If the woofer cone springs back out immediately there is a leak. It should take about 2 seconds for it to slowly return.

If you need to seal them, do NOT use any home-brew remedy. ONLY use the butyl rubber sealant that Roy cooked up. It's sold by ebay seller Vintage AR or, as a CSP member, you may be able to purchase directly from Roy at a lower cost.
