Intelligent minds require great sound also. When one reaches 50 years of age it's the midrange that matters most of which this speaker is magic. This could only have been accomplished with an entity like the BBC who had unlimited funds and enlisted the best electrical and acoustic engineers of the time (1974), to design a speaker with the most accurate vocal reproduction possible within a specific footprint. Even with today's improved technology there are few speakers at any cost with the ability to reproduce vocals and acoustic instruments as realistically as the LS3/5A.
