Fit questions
Do I get one surround or a pair?
A pair. This kit has 2 surrounds, enough to repair both 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.

Technics Speaker Compatibility & Fitment Guide
This premium 10-inch foam surround repair kit (Model 10F#1) is engineered to restore the proper acoustic alignment, high compliance, and original bass transient response of classic Technics loudspeakers.
Over the decades, factory polyurethane edges naturally degrade, dry-rot, and crumble. Replacing them with our premium foam surrounds eliminates muddy sound, protects your voice coils from hitting the magnetic structure, and fully recovers the punchy low-end and warm tone your Technics system was designed to produce.
