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.

Yamaha Speaker Compatibility & Fitment Guide

This premium 8-inch foam surround repair kit (Model 8F#1) is specifically engineered to restore the precise acoustic suspension, mid-bass performance, and low-frequency transients of vintage and modern Yamaha loudspeakers.

Replacing deteriorated, dry-rotted foam prevents voice coil misalignment and friction, fully recovering the pristine, balanced response your Yamaha monitors and subwoofers were designed to output.
