They were are successors to Tannoy Monitor Red 15, and were first launched in 1967. The “Monitor Gold 15” is a common name, but their factory model name is LSU/HF/15/8.
#Tannoy dual concentric motor drivers#
Tannoy Monitor Gold 15in are the largest (and most expensive) drivers in the Monitor Gold range. Having heard Tannoy Monitor gGld drivers in many different closed and bass reflex enclosures, I am confident that enclosures used for this review allowed the drivers to show their character and basic sound qualities. Nonetheless, from what I have heard, Tannoy enclosures from the basic range are not very rigid and people who buy them, sooner or later replace them with better quality DIY cabinets. 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.
