Drawing a total blank on this one; looks purposeful, though.
EDIT: FWIW I've never seen Sonab speakers like that; unless they're post Stig Carlsson, perhaps. http://www.carlssonplanet.com/speakers.php
The drivers do look like they might be Scandinavian, though, I'll give you that!
The first thing that came to my mind was Sonab. With the down firing woofers, wheel casters, and top mounted mids and tweeter. Probably couldn't go wrong if the price is right.
Hey Ed, I was looking at those as well. The funny thing is they popped up on CL a few months ago and someone else local posted a thread here just like this. Speculation at the time was also for Sonab. I guess they never sold. Let us know if you get them, they look pretty interesting.
The lower cab looks quite Sonab to me, rollers & all. The upper cab not so much. Maybe a hybrid of some sort.....interestng none the less.
FWIW Sonabs while being very unusual are quite musical! I heard only one model but it left me impressed none the less. It needed some cone tweeter replacements and had a couple off set 8" mid bass drivers. Did not impress me UNTIL I fired them up and went WOW! Bad news they are real dust magnets!
