Hello All, I have been looking on Craigslist for speakers lately and I have a couple of questions. Obviously a pair of Advent Laureae speakers from back in the day for $100 are probably better than anything I could buy new now for that price. However, how much different are the speakers, crossovers etc now as compared to then? Also, is it possible to use the cabinet from an older speaker and replace the components to modernize the box? Thanks.
