My wife has finally prevailed in her long-held belief that "those things are just too big!" so I am listing these with the hope that someone else will have a chance to enjoy them as much as I have. I am the second owner and as such unfortunately have no boxes but I live roughly 3 hours from Minneapolis and Chicago so I might be able to meet up to reduce your drive if you were coming from either area. I listed these as a 7 to account for their age and the light scratching on the tops (that effectively disappears if you give them a good waxing now and then). Otherwise, they are in nice shape. Here is some info on them if you arent already familiar with these lovely speakers:
A high sensitivity speaker @ 95dB sensitivity. Great for tubes and solid state and absolutely amazing for vocals and brass (and frankly most content - Alan Yun, Silverline's president, had them playing a series of drum tracks when I first heard them with some tube amps he was building. The bass was amazingly controlled). These are beautiful floor standers that do so many things right, I only am selling as a result of an upcoming move.
From a soundstage! review by John Potis - "Smooth, effortless and utterly engaging midrange" coupled with tight, highly damped bass; "transparent yet friendly personality " -- "no part of the frequency spectrum is emphasized at the expense of the rest."
Silverline specifies a sensitivity of 95dB, an increase of 2dB over the older model, and the same easy-to-drive, tube-friendly 8-ohm nominal impedance. The crossover frequencies are 600Hz, 1200Hz, 2000Hz and 3500Hz, and the frequency response is given as 25Hz to 28kHz with no tolerance stated. Speaker connections were made via very sturdy dual sets of gold-plated five-way binding posts, which are recessed into the bottom rear of the cabinet. Silverline recommends a minimum of 10 watts to drive the speakers and a maximum of 1000 watts.
