Fit questions
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.
