 Posted: Sun Jul 26, 2009 3:22 am Post subject: Voicing early KEF speakers |
 |
|
Many quality manufacturers "voice" their products with music, vocals and spoken word. Since I am not a speaker manufacturer, I have no direct experience with this but I presume that when developing a new speaker or a driver/tweeter, along with endurance and frequency tests, they also perform listening tests.
I know that some (all?) manufacturers use pink noise (or white noise?) to see how their speakers perform.
Does anyone know what KEF used as test records to develop and tweak test records?
As engineers generally were not long haired hippie types, I would guess that they used vocalists (Sinatra? Petula Clark? Mantovani?) and big band or orchestras to see how their products sounded before releasing them.
Would early KEF speakers shine with this type of music?
Or am I totally out in left field?

I'd say that that list was a little more than a hint!!!!!
Thanks for posting that - I might poke about and see if I have any of that but I gave away a few hundred classical LPs a few years ago. I still have about 100 or more... including a 10 or 11 LP set of The Rings! Eeek! First LP, first side.... the orchestra is warming up!
