Speaker Size
Use the tables below to determine the correct surrounds for your speakers.  The measurements listed here do not have to match your speakers exactly for the surrounds to work. Some surrounds will fit better if they are gently stretched out or if they are a little too big. The most important thing to remember is that the surrounds must overlap the speaker cone on the inside edge and the speaker basket on the outside edge. If the measurements listed below do not match your speakers, please call. We may have other surrounds that will fit your speakers.

Dust Cap Size
We stock many sizes and types of dust caps and most kits will include new dust caps. When measuring dust caps, make sure you include the lip of the cap, not just the dome itself. Some caps have no lip (most JBL’s), but most have a lip which sits on the cone.

Rubber Surround Kits
(2 surrounds per kit) Upgrade your old foam surrounds with rubber if the sizes fit! Kits are notated either angled or flat, which is the point where the surround is attached to the cone.
