Fits 23 models – see the full list ↓

Not every compatible model is listed. If yours isn't, check the OD and ID or contact us and we'll confirm the fit.

You need this if: the foam ring is crumbling, cracked or missing, the bass sounds weak or "farty", or the cone rattles at volume.

Step-by-step repair video →Doesn't fit? measure your OD & ID and use the Surround Finder.

Fit questions

Do I get one surround or a pair?

One. This kit has 1 surround, for repairing a single driver. Order two kits if you are repairing a pair of speakers.

My model isn't listed. Will it still fit?

Measure the outer diameter (OD) and inner diameter (ID) of your old surround and compare them with the measurements on this page. If you are unsure, contact us with your measurements and speaker model and we will confirm the fit before you order.

Can I use rubber instead of foam (or foam instead of rubber)?

We recommend matching the material of your original surround. Foam and rubber differ in weight and stiffness, which changes how the woofer moves and how the bass sounds.

  • Roll Over Diameter: 270MM
