Yes, that’s an Exposure 15. Had that setup running from 1992 to 2008. Now using the same amp with Tannoy DMT 15’s. The Quads are in storage.

I find dipoles fascinating and might end up one time with a dipole.

Not sure which Quads you have but some people are also experimenting with the angle of the Quads (not toe in) but I am sure you know.
I think we all hope you manage to get the best out of them because we all had a lot of benefits from your extensive testing of various things.
This is really a great forum with great and helpfull people and fruitfull discussions.
I have what are often referred to as the Quad ESL57s. The true original name is actually just the Quad Electrostatic Loudspeaker or ESL for short. But when the ESL 63s came out (confusingly in 1982, named the 63 because that is when Peter Walker came up with the idea) the ESL started being called the ESL57 to differentiate it (it was introduced to the market in 1957). I prefer the original name but there are so many Quad ESLs it does cause some confusion. The original ESL is the only one without a model number and the only one not based on the delay-line fed "point-source" design of the 63 (which I don't particularly care for).

I will indeed be experimenting with the rake angle of the Quads as I tune the setup.

I find it interesting that John has gone from Quad ESLs to a 15" two way with horn loaded tweeter and dual ports when I am going in the opposite direction, admittedly with a different speaker.

Here is a stock photo and an early piece of literature:

I have now two positions which seem good but deep inside me I have a feeling both are traps

Position 1
37,5 cm from the back wall
1,499 Meter speaker distance
no toe in

Position 2
39,8 cm from the back wall
1,499 Meter speaker distance
no toe in

both sound good
Position 1
music flows very nice, tunefull, transparent but also boomy bass, very dynamic, sounds good at low volumes

Position 2
music flows nice, bass more controlled, more on the thin side, good at high volumes



tested positions between the two but none of them are as good as one of the two
I have a feeling the system can do more even though what both positions deliver sounds really good.

Don't you have any other tune-demmers in your neighborhood, that could help out?

Hi Tendaberry,

I am living in a Linn/Tune Dem "diaspora".
Actually you are the closest I know of and you are always welcome to visit me (I am still 400km away in Thuringia).

I might ask for a tune dem demo at a Linn dealer in Erlangen to be sure what I do is consistant with tune dem.
Actually Position 2 seems to be the one to fine tune.

You have to learn to make clips. The respons time is very low compared to the other options....... :-)

yes you are right
I am actually using the clips to learn and understand if I am coming to the same conclusions like you meaning I am on the right path.
For your last clip presented it was clip A out of the two ... but it seems you meanwhile added another clip.

I am glad. This is what I have been hoping for all along that my clips could be useful to others. :-)
