John, I forwarded to George the email you sent me with your impressions of the two. I figure you wouldn't mind, especially with your PC problems at home.:D
Concerning the Diluceos, according to Danny, the dual Eton woofers are in as about as big an enclosure as they need to be. We've talked it over and he said that we could simply build the speakers with the same internal dimensions and volume but with longer sides back and baffle to create a tower...
John, The great thing about the GR speakers is that it's very easy to get 2 sets of binding posts if that's what you want. I just have to drill a couple of extra holes! :)
