IMHO ESL-60 is just a 6 panel speaker (like 989, 2905 and 2912) with the only difference that the panels are rotated 90 degrees.What's your opinion about rebuilding one big ESL from two ESL63? Two options: horizontal or vertical stacking, latter potentially better like new model ESL-60 (line source?).
No line source, no stacking.
4 bass panels, 2 top, 2 bottom and 2 mid/high panels in the center (d'Apolito) with the delay rings just like other 6 panels Quad models.
We were talking ESL-63 and ESL-60 here right?I use 3 bass panels ESL57 and tweeter panel on hinges. Very good setup.
ESL-57 is a totally different design
4 bass panels, 2 top, 2 bottom and 2 mid/high panels in the center (d'Apolito) with the delay rings just like other 6 panels Quad models.
Not quite, they are narrower, so the pressure feedback rolloff happens higher up in frequency. I bet money, they haven't tweaked anything to compensate for it either.
So they are potentially worse than the other 6 panel quads.
