They most certainly did deign the networks to be able to handle the high power from the amps..I have the original B-139 kef woofer that IMf used and it was good for maybe 25 to 30 watts.The big amps that were 200wpc and more are the amps that were sold with those type speakers and of course people would crank the SHI- out of them..They were blowing mids and tweeters and woofers left and right and they were melting the cones to the speaker frames at times.
John Hayes which was IMFs owner said we need to have new drivers that can handle power and thats when they started using things like ferrofluid drivers and woofers which had heavier voice coils with Kef redesigning the B139..
If you look at the imf pro monitor 4 speakers,they have 4 drivers and twice as many parts in the network as the monitor 7 which is the same speaker with the newer drivers.
So yes they did make major changes and the efficiency tells a lot..Im not saying every speaker did,but many of the speakers sold in the 70s were too desirable unless they were maggies or acoustats or maybe the infinity servos or some JBLS..Even klipsh got better finally.
