Think of its speaker like a "sealed" driver where as the esw11 is like a "bass-reflex" driver in that it has a port hole directly in back of unit.
Now, side by side, the drivers look EXACTLY the same .… with the white material around the edges, but the voice coils are tuned differently...
Also the yellow felt reflects this as the es10 yellow felt is a circular piece, while the esw11 is a "donut" shaped piece as it has a hole in middle so the rear of the driver "sees" the wood and the port hole on top..
Sooo when modding the es10 there would be more change due to how it was originally tuned with higher damping..
while the esw11 probably less affected or easier controlled when modding with larger cup like from say, Martin Audio..
That being said, member Bill-p further modded them further to even greater heights as they have more potential than the stock form wich is compromise for portability.
I would PM him for further info..
