So
here's a link.
It's not impossible to pick up but not having feet installed makes it easier to slide.
Here's a closer shot of about a 3 inch smudge mark. I think I did it and I think it's dust and I think it will vacuum out but felt pretty sure that I didn't feel like dragging out the vacuum.
The top is decent and it's packed pretty well ... well, exceedingly well.
I think the guy I bought it from had it listed as an 8 on Audiogon and asked $550. I got it for $425. It's a nice sub. My options are sell or buy another one and I already have a cheaper sub solution that exceeds my needs. My fascination with dual subs demands immediate action on this mono monstrosity. I guess maybe if you have one of these to sell I might be interested.
