In the studio we had a pair of Tannoy Little Golds in the main room and one day we had a group of young learning disabled folk in on my day off. One of them had stuck a broken drumstick into the surround of one of the cones which left a nice 1/2" tear in it
Copydex and a piece tissue paper to the rescue and all was well luckily. The repair was still going strong after about 10 years when I retired, despite the Tannoys regularly getting a good thrashing at the end of many a mix session
