3" Poly Speaker Dust Cap is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Excellent replacement dust capsThe contoured flange makes for an OEM-like fit. Excellent choice for replacing rotted-out or punctured dust caps.I spent a good while cleaning the cone, removing remnants of the original cap. Make sure the loose particles stay away from the driver's motor.I used these on paper cones, which is fine ... just have to be careful that the adhesive you use works well with paper and plastics. If you've got paper cones, might be better to go with paper.

Parts Express 3" Poly Speaker Dust Cap

Do you have better photos to demonstrate the texture? Do you know off hand if this is a suitable 'replacement' or fit for the JBL LSR4328P?

Asked by: TableSyrup
This dust cap will replace most poly dust caps, though it may not be an exact match for fit and finish. It will help you restore most speakers to working condition. However, if you need an exact cosmetic and performance match for a critical application, you may need to contact the manufacturer of your speakers for a direct replacement.

We do not have anything that will act as a replacement dust cap for a JL W7 woofer. These parts are proprietary and only available from JL directly.
