Drive unit technology has moved on massively from the 70' & 80's as has cabinet design. Nowadays computer technology has revolutionized speaker driver design. Modern materials are lighter, move faster, and their movement behaviour can be seen in 3D on a computer screen.
A modern budget design from say B&W, KEF will noticably outperform an old Chorale.... I know, I used to sell them!
Which way around was your "used to sell them" ?...
It's a brave statement either way, for every point you make different interpretations for why that is so can be given, not simply that because of the points given it must therefore conclude that they are better....no 3d image can show the results of the myriad conditions in which the speakers will be used. As for lighter materials this could be said to be for many reasons, lighter materials are generally cheaper because they are easier and more cost effective to transport and so it follows that far more can be transported at a time + natural resources where available are replaced with modern day substitutes, I'm not saying that all the reasons are purely to cut overheads and increase shareholders dividends but to say that everything is used purely to achieve better loudspeakers is, in my view far too simple to be the truth.
Which way round? I was a HiFi Dealer and enthusiast involved with KEF from the mid 70's to 2012 so I do know my subject. I respect the OP likes that sound, but it is outdated. It is incorrect to think that computers have no place in speaker development any more than they play a great part in any development of technology.
KEF have replaced their 'old school' engineers left over from the days of Raymond Cook their founder and now have a team of acoustic engineers most whom are in their twenties(obviously computer savvy), turning out some amazing quality speakers.(A young girl developed their 'Blade' technology) (My own are KEF LS50)
Do you seriously think that they developed them without 3D technology? watching the behaviour of drive cones and cabinet vibrations?
Modern materials like carbon silicate (Used by Dynaudio), Kevlar (B&W),super light Manesium alloys, etc have much improved drive cones over the old heavy plastic/bextrene ones from way back.
Lighter materials can move quicker with musical transients so there has to be better sound and much improved phase response especially with large bass drivers.(Peter Walker of Quad would have died to get his hands on Mylar when he was developing his electrostatic speakers but it wasn't around in those days)
I used to have a pair of KEF Ref.104AB's, in their day a highly respected speaker, but listening to them now they are awful compared to a new equivelent.
I was the first dealer in the UK to Help Eclipse TD speakers get off the ground after they asked me to give opinions on them both at my dealership and Abbey Road Studios, (John Williams, and a host of other famous musicians, including the Royal Acadamy of Music use them) I've advised John Williams on his own studio set up, Steve Hackett(Ex Genesis) (KEF), Fish (Marillion).
I still have the original Rogers LS/35A BBC speakers which are now boxed up as I use the LS50's (a direct development from them) exclusively as the originals are not anywhere near as good.
As regards to your statement regarding shareholders etc, these companies like KEF, B&W would have gone long ago without computer aided development!
Anyway respect to the original poster I hope he gets them up and running.
