Hi,

I compared my 1974 pair of ESL57s against a pair of newish TDL
speakers using a test CD with stepped tones and measured the output
with a sound level meter. The high-frequency roll-off of the ESL57s
was very noticable. The higher tones (10kHz up) were there but the
volume dropped off rapidly.

Actually you may not have a problem with the ESL's per se but with the
listening position. The treble panels in the ESL 'beams' the sound to
one specific spot.

John: Could you tell us more about the microphone and speaker locations,
etc? Also could you give the details of what sound levels you measured and
at what frequencies? My initial reaction is was the same as Mike's, but it
would help us to diagnose/advise if we have more detailed/specific info.

Slainte,

Jim
