I used the kit to repair a 40 year old pair of Realistic stereo speakers with 8 woofers. I pays to practice applying the adhesive. You need to let the adhesive sit for a few minutes once it is applied and let it get tacky before applying the new gasket to the cone, otherwise it won't stay in place and you will get the adhesive where you don't want it to be. Once I figured this out all went well. The speakers work like new again.
