Vintage Tannoy Cabinets

Years ago I sold a pair of 15" Tannoy Red drivers. The buyer didn't want the cabinets, so I kept them and put in some KLH speakers (I'm not an audiophile). My question is, are these cabinets worth anything? They're in very nice shape. Just wondering if they're completely worthless or have at least some value. I'd like to create more space in my living room. 

Thanks in advance.
