Hi Steve. I think the Rhythm is "free field," which means it wants a good bit of space, unlike NC's "near wall specific" designs like the Big Kat. As Tobias says, George is easy to deal with; give him a shout. I think he's located in upstate New York; he might have a customer close to you, as well. I'm guessing cabinet work by Lee Taylor (with custom veneer from Certainly Wood) would add 1000-1500 to the kit price; this would result in stunning visuals.
Just to thicken the mix, a couple of other people who do very musical speakers in the North Creek vein are Rick at Selah and Fritz at Fritz Speakers.
Keep us posted! John
