I don't know if the other folks approve of these methods. Yes, I definitely coat the corrugated section of the outer circumference of the speaker (the "surround") with a thin layer of contact cement. You can spread a little cement around the tear, place some toilet paper there as a patch and push it all together. When I was a kid, I would coat a weal cone with a layer of Elmer's Glue - All. This DID strengthen the cone, but I bet others are cringing as they read this. There are also spray contact cements. However, you want the stuff that dries. The stuff that stays sticky will attract dust.
Whatever technique that you use, don't cause the cone to warp. This may affect the centering of the voice coil, and rubbing of the voice coil on the pole of the magnet will cause distortion.
Hope this helps.
