This\u003cbr\u003e\npolypropylene dome dust cap drops straight onto the cone, seals the gap, and\u003cbr\u003e\nbrings the driver back to looking (and sounding) like new.\u003cbr\u003e\n\u003cbr\u003e\n### Why Polypropylene\u003cbr\u003e\n\u003cbr\u003e\n- **Lightweight** – adds almost no moving mass, so the cone keeps its response\u003cbr\u003e\n- **Rigid and self-damping** – the domed shape resists flexing and helps keep\u003cbr\u003e\n  the midrange clean instead of honky\u003cbr\u003e\n- **Moisture resistant** – PP doesn't absorb water the way paper or fabric\u003cbr\u003e\n  caps do, so it won't sag or stain in a humid car boot or basement\u003cbr\u003e\n- **Easy to finish** – takes paint and marking pens well if you want a custom\u003cbr\u003e\n  look\u003cbr\u003e\n\u003cbr\u003e\n### Pick the Right Size\u003cbr\u003e\n\u003cbr\u003e\nMeasure the **outer diameter of the dust cap opening** on your cone (or the\u003cbr\u003e\ncap you're replacing), then choose the closest match below. When in doubt, go\u003cbr\u003e\n1–2mm larger – you can trim the flange edge slightly, but you can't stretch a\u003cbr\u003e\ncap that's too small.\u003cbr\u003e\n\u003cbr\u003e\n**Available diameters:** 20mm · 22mm · 24mm · 27mm · 30mm · 33mm · 35mm ·\u003cbr\u003e\n40mm · 45mm · 50mm · 54mm · 64mm\u003cbr\u003e\n\u003cbr\u003e\n### Specifications\u003cbr\u003e\n\u003cbr\u003e\n| Item | Specification |\u003cbr\u003e\n|---|---|\u003cbr\u003e\n| Product type | Dome dust cap \/ dust cover |\u003cbr\u003e\n| Material | Polypropylene (PP) |\u003cbr\u003e\n| Shape | Convex dome with mounting flange |\u003cbr\u003e\n| Diameters | 20 \/ 22 \/ 24 \/ 27 \/ 30 \/ 33 \/ 35 \/ 40 \/ 45 \/ 50 \/ 54 \/ 64 mm |\u003cbr\u003e\n| Colour | *(按实物填写，如 Black \/ Grey \/ Matte)* |\u003cbr\u003e\n| Height \/ depth | *(按实物填写)* |\u003cbr\u003e\n| Application | Subwoofer, woofer, mid-bass and full-range driver repair |\u003cbr\u003e\n\u003cbr\u003e\n### Installation Notes\u003cbr\u003e\n\u003cbr\u003e\n1. Remove the old cap carefully and clean the cone surface around the opening.\u003cbr\u003e\n2. Test-fit the new cap to check the flange sits flat all the way round.\u003cbr\u003e\n3. Apply a thin, even ring of adhesive to the flange – CA glue, epoxy or\u003cbr\u003e\n   speaker-grade contact adhesive all work.\u003cbr\u003e\n4. Press down evenly and hold until set. Wipe off any squeeze-out at once.\u003cbr\u003e\n5. Let it cure fully before playing the speaker.\u003cbr\u003e\n\u003cbr\u003e\n### FAQ\u003cbr\u003e\n\u003cbr\u003e\n**How do I measure for the right size?**\u003cbr\u003e\nMeasure across the outside of the hole in the cone, not the old cap's flange.\u003cbr\u003e\nA calliper is best; a ruler across the widest point works for a rough match.\u003cbr\u003e\n\u003cbr\u003e\n**Can I paint it?**\u003cbr\u003e\nYes. Lightly scuff the surface first and use a thin coat of plastic-compatible\u003cbr\u003e\npaint so the extra weight stays minimal.\u003cbr\u003e\n\u003cbr\u003e\n**Will this fit any brand of subwoofer?**\u003cbr\u003e\nIt's a universal part, not brand-specific. Fit is determined by diameter alone,\u003cbr\u003e\nso measure first rather than matching by model number.\u003cbr\u003e\n\u003cbr\u003e\n### Package Includes\u003cbr\u003e\n\u003cbr\u003e\n- 1 × PP dome dust cap (size as selected)","brand":"DIYMars","offers":[{"title":"20mm","offer_id":53517059850551,"sku":null,"price":2.99,"currency_code":"USD","in_stock":true},{"title":"22mm","offer_id":53517059883319,"sku":null,"price":3.26,"currency_code":"USD","in_stock":true},{"title":"24mm","offer_id":53517059916087,"sku":null,"price":3.56,"currency_code":"USD","in_stock":true},{"title":"27mm","offer_id":53517059948855,"sku":null,"price":3.66,"currency_code":"USD","in_stock":true},{"title":"30mm","offer_id":53517059981623,"sku":null,"price":3.76,"currency_code":"USD","in_stock":true},{"title":"33mm","offer_id":53517060014391,"sku":null,"price":3.76,"currency_code":"USD","in_stock":true},{"title":"35mm","offer_id":53517060047159,"sku":null,"price":3.88,"currency_code":"USD","in_stock":true},{"title":"40mm","offer_id":53517060079927,"sku":null,"price":3.88,"currency_code":"USD","in_stock":true},{"title":"45mm","offer_id":53517060112695,"sku":null,"price":3.88,"currency_code":"USD","in_stock":true},{"title":"50mm","offer_id":53517060145463,"sku":null,"price":3.99,"currency_code":"USD","in_stock":true},{"title":"54mm","offer_id":53517060178231,"sku":null,"price":3.99,"currency_code":"USD","in_stock":true},{"title":"64mm","offer_id":53517060210999,"sku":null,"price":3.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0894\/5562\/4503\/files\/57_210eaf25-41d7-42f5-a88d-439791dcd7ed.jpg?v=1793842512","url":"https:\/\/www.diymars.com\/pt\/products\/subwoofer-dome-dust-cap-pp-20-64mm","provider":"DIYMars","version":"1.0","type":"link"}
