djones51,
Yes, I agree the best way forward would be to have loudspeakers that are reasonably neutral - both in the recording studio and the home.
I’ve no doubt that many users of brands such as ATC, B&W, Genelec, JBL, Neumann, etc will feel some assurance that similar speakers are being used today in the production of the music they listen to.
On the other hand when it comes to music recorded 60/70 years ago there seems to have been a huge variance in the monitors used back then for playback as illustrated in this Wikipedia Studio monitor article.
https://en.m.wikipedia.org/wiki/Studio_monitorWhat are you supposed to make of the following statement?
"The Altec 604 had a notoriously ragged
frequency response but almost all U.S studios continued to use it because virtually every producer and engineer knew its sound intimately and were practiced at listening through its sonic limitations."
Or this one referring to the 50s?
"As a result, pretty well every U.S studio had a set of 604’s and every European studio a Tannoy Dual Concentric or two."
No wonder these classic designs/brands still have a loyal following. To get close to what the artists, producers and technicians heard back in the day you’re going to need similar playback speakers or settle for a more modern take.
No wonder that the remastering of vintage recordings is such a tricky business. Especially if you want to retain that important ’authentic’ period feel many of us do whenever we want the occasional trip to travel back to those apparently more simpler times. Ah, those priceless memories!
Anyway here’s another article, one featuring some of the recording studios where most of this music was recorded.
