Univox 4X10 Bass Cabinets???

Hey All,

A pair of these, Univox 4X10 Bass Cabinets, popped up on the local craigslist, I am not so sold that they are bass cabinets. I really cannot find any information on them after a search on talkbass or google, they intrigue me as they are a vertically oriented 4X10 and somewhat cheap. I have asked for a little more information on the speakers from the seller.

Any thoughts on what the speakers may be? and if these would be a decent bass cab? Or further is this something worth flipping into a bass cab if it will not serve as such at the moment?

Thanks
