Have to disagree with you. (Not a design approach that anyone uses today.) Marantz had active tube crossovers in the 50's not sure if they were first ones to make active crossovers. Do not feel like researching right now and Marantz is the earliest I can think of. JBL, Altec Lansing, Myer sound all had active speakers in the mid 60's. So, KEF was not new to the active speaker party. The MTM style mid & highs was also developed in the 60's. So that was not new to anyone either.
So, when KEF came out with the KM1 in 1982 nothing about it was groundbreaking technology. Drop one speaker and you might break the ground the damn things weighed 308 pounds each!!!
But as far as being a design approach no one uses today is just not accurate. Everything about the KM1 is still being widely used today such as MTM mid & high arrangement, multiple bass drivers, and onboard amplifiers with built in active crossovers are all still being used today in speaker design. Maybe not all in one speaker but all the different aspects of the KM1 are still very popular in speaker design today.
And with Class D amps that are small light weight powerful and producing little to no heat the active speaker market is still growing and has not reached its peak yet.
So, looking at it from a speaker designers' perspective yes everything about the KEF KM1 is defiantly still being used in speak design today.
