Cerwin Vega bookshelf speakers

I have these Cerwin Vega ginormous bookshelf speakers not sure from what era. I know Vegas are good speakers. They work perfectly fine. A few dings and dents and scratches and whatnot on the boxes from use over the years. Not sure what to list them at but will entertain offers. Trades for maybe a decent working large format 3D printer or other audio gear? I'm in really no rush to sell as I used them daily they were in my 7.1 surround sound setup. I have way too many speakers and some things got to go. Best reasonable offer today.
