#Tannoy dual concentric elliptical drivers#
More about building of these can be found in DIY section of this page.Īs you gathered by now, I bought these drivers without any enclosures so I was not able to review any particular model of vintage Tannoy speakers that use Monitor Gold drivers (for instance Lancaster or York). Many hours of soldering and even more hours of wood working after, and I was able to test these drivers with crossovers based on very good quality components and in heavy, sand filled, 25mm thick plywood, 210l bass reflex enclosures. And this was done using crossovers with old electrolytic capacitors. When I first plugged in these monster drivers in hardly optimized test cabinets I was very impressed with their sound. This has never happened, and for over 30 years these drivers were waiting for me in storage. Afterwards, drivers were taken out of the enclosures, with an intention of building better enclosures. The gentleman used them in his private recording studio for couple of years during 70s. They were bought from London, from the first owner who in 1968 bought them in Lancaster enclosures. Couple of years ago I have become a lucky owner of these beautiful drivers. Tannoy Monitor Gold 15″ (LSU/HF/15/8) were on my wish list since I discovered coaxial speakers and the theory behind putting two drivers on one axis.
