The Esg really sounds wonderfull. Very smooth and natural, the air on cymbals is very close to live in my opinion. I did use an Eminence PSD2002 with their horn (using the pi compensation network) for a couple of days before the Esgs arrived. While this was at work, before I moved the speakers home, I found the ribbons more refined overall with a wider soundstage. I could really live with the PSD2002. The crossover is external so I can change it quickly - I may have to try the compression drivers at home to hear the difference again, but right now the ribbons sound so good its a low priority.

Hopefully I'll have the components soon for the zobel. The midrange sounds good right now even without it, the woofer's Le is .71mh with a 58 ohm Zo, so maybe the crossover's inductor is damping the peak a bit? I was going to run a spice sim. but haven't yet.
