This is a pair of Vintage Classic Tannoy Silver Dual Concentric LS LSU/HF/15L 15 inch drivers manufactured in England between 1951 - 1953. They are in spectacular condition and perform perfectly. Serial numbers are 012575 and 015994. The material on both drivers have no cracks, holes or any other defects. The material is not dried out or brittle. The original black coating on the surround is still tacky, as it should be. Cosmetics are excellent. The cabinets are scuffed up a bit since they are nearly 60 years old. The Crossovers work great and are in perfect condition. There are no problems with them at all. Tannoy Monitors have earned a reputation for accuracy, clarity, and with the upgrade from Black to Silver, prodigious output. Please check out a short video demo that I have produced to demonstrate their unbelievable condition and sound. http://126.96.36.199/Media/TannoySilverDrivers.wmv. More Pics available.
