They're just as tall as my JBL 4319s but a few inches wider and a few more even deeper so the Wharfedale Litton stands can easily handle them. Those stands come fully assembled and are sturdy as heck.
As for the Music Direct catalog, I just went through it and there's also going to be a KLH model 7 (with a 13" woofer) and Wharfedale is also getting in on the retro act with their Dovetail (with a 10" Kevlar woofer).
All the best,
