Sorry once again your wrong. Altec's main driver I think you mean the cone acts as a waveguide not true the Altec have a horn and do not use the cone as a waveguide. Early Altec 604's used sectorial horns later versions used the manta ray a non-sectorial horn.
Now let's look at basic physics of speaker's cone larger cone speakers move less to produce sound than smaller cone. So, a Altec 604 has a very small xmas aka the amount of travel a cone can move measured in mm a little tiny 6.5" KEF cone has a much higher excursion or xmas or cone travel meaning while the large 604 cone is not even moving 2mm and producing bass the small 6.5" KEF cone would have to move 6 mm to 8 mm to produce good bass. So, throw that argument out the window.
And the KEF crosses over at 400 HZ not even in the ballpark not even in the same country as the ballpark. The tweeter used on the KEF coaxial could not be crossed that low a matter of fact no dome or ribbon tweeter will cross that low or nowhere near that low. The higher the quality tweeter the lower its crossover point the cheap little, tiny magnet tweeters on a KEF uniq driver probably crosses over well above 2000 KHZ
And a speaker cone moves more the lower the frequency goes so Altec 604's crossover at 1600 KHZ so if the 604 used the cone for the waveguide it would be moving less at the 1600 KHZ crossover point than the 400 HZ you claim the KEF crosses over at due to the fact a speaker's cone moves more at lower frequencies than at higher frequencies.
At what point will you stop guessing and actually fact check yourself before you post? correcting you is getting old already.
As far as Altec being better than KEF that is well known by even casual audiophiles. Altec 604 the world's first coaxial invented before the nuclear bomb or jet airplane is iconic speaker and is still being made today. Used in over 83% of recording studios over from the 1950's into the 1990's something KEF cannot claim since they only made one studio monitor the KM1 used in only one studio not 83% of studios worldwide like the world famous Altec 604.
Also, the 604 was chosen by pink Floyd and used in arguably the greatest sounding concert tour of all time Pink Floyds the wall.
I am not just a speaker designer I am an audiophile history buff I love history more than designing speakers guess I am just a nerd!!!
