ESW-8 has 8-inch driver, while Power 10 has 10-inch driver. It is also on sale[newegg.com] with promo code EMCJJHG76 for $120 shipped free.
You can't go wrong with this combo for a small room, and these are the best price I have ever seen. I purchased the Energy Take 5 3 months ago from eBay for $170 and the Power 10 from Newegg for $180. Yes, call me dumb and I thought they were good deals at that time....
Quote from Khan of Khronos :
I think the one in the pack is an ESW-8, whereas the one above is a "Power 10." Not sure about the differences, though.
