Yeah, $5,000 for the lot seems really high. It does look like it's been relisted though.
How often do they come up on sites like this?
I think Steveo is right that people want them chopped, but personally, I love the sound and overall aesthetic of the 206. Not everyone gigs, and the 206 cabinets sound so good for home and studio use. I get sad every time one of these gets chopped.
