Esl 57

Tenson · 18th March 2008, 04:06 PM

Hi,

Anyone know where I can find an off-axis response plot of the ESL 57? Someone has asked me to make a pair of tweeters to match them and I can only find what I want for the ESL63!

Thanks for any help!

Hi,

Reasonable horizontally and poor vertically from what I recall seeing.

Matching would be difficult, possibly pointless ?

In other words a tweeter running over the last octave could be set
at a levell that fills in but not fully compensates vertically whilst
being lower level on

conjecture though...

FWIW IMO a Neo3PDR used dipole (without the rear chamber)
might be a good option, response is very overdamped / low Q
open backed and it would only need a simple c/o.

/sreten.

Make sure the treble can be driven and the treble panels have not lost sensitivity

I seem to remember people using Decca ribbons, but it may have been with stacked panels.

Hi,

I already have plans for what to do in terms of making it, I just need off-axis plots. I did find some but they are poorly scanned and hard to read. Will do though.
