At a resale shop today I bought 2 speakers they were about 28" tall by 18" wide and about the same deep. I took the backs off of them and one held a Knight kn-612c and the other held a white speaker cast and says made in england. It is totally different than the 612hc but still a 3 way. The white one has a cylinder attatched to it, I think its a crossover. Any ideas about the quality of these? Thanks.
