8 inch surrounds fit the mid-size woofers found in classic bookshelf and floorstanding hi-fi speakers, with outer diameters typically between about 193mm and 196mm and inner diameters ranging from around 135mm to 148mm depending on the cone profile of your driver. Both foam and rubber are stocked at this size, including tinted foam options for a closer cosmetic match on some vintage models, so you can replace like-for-like or upgrade the material. Buy the surround only if you're happy fitting it with your own adhesive, or choose a full repair kit with two surrounds, T7000 glue, a brush and instructions for a complete pair rebuild.
Inner diameters vary more at 8 inches than at smaller sizes, so measure the outer edge of the basket and the inner diameter at the cone's edge carefully before ordering. If you're unsure whether this fits your speaker, drop us a message with your make and model and we'll help you match it correctly.
